Securosys Secrets Engine for HashiCorp Vault

This plugin implements a platform-agnostic REST-based HSM interface with zero library installation, while eliminating connectivity hurdles by using secure web connections (TLS). This facilitates the use and deployment in clustered and multi-cloud environments. Moreover, all Securosys HSM innovations like hardware enforced multi-authorization and high-performance encryption (ECIES, AES-GCM) are at one's disposal, for Vault Enterprise and Community Edition.

Manage keys securely stored on the HSM
Perform cryptographic operations on the HSM
Use enhanced Primus HSM features such as high-performance encryption (ECIES, AES-GCM), or hardware-enforced multi-authorization workflows for compliance, signature services, or blockchain transactions.

This plugin is actively maintained by Securosys SA.

How to run

Register the plugin

In production mode the plugin has to be registered manually. Add the following parameter in the configuration file config.hcl

plugin_directory - must contain the absolute path to the directory where the plugins are stored

Command to register the plugin

$ vault plugin register -sha256={binary_checksum} secret securosys-hsm

Upgrade the plugin

To upgrade a binary of an existing working plugin, follow the steps below:

Copy the new plugin binary to the plugin_directory.

Register a new version of the plugin.

$ vault plugin register -sha256={binary_checksum} -version={new-version} secret securosys-hsm

Tune the existing mount to reconfigure it to use the newly registered version.
```
$ vault secrets tune -plugin-version={new-version}  securosys-hsm
```

Reload the plugin

$ vault plugin reload -plugin securosys-hsm

How to enable the plugin

After building the plugin, before running it on test server, it must be enabled with the following command:

$ vault secrets enable securosys-hsm

The result should be

$ Success! Enabled the securosys-hsm secrets engine at: securosys-hsm/

Configure the plugin

Configure the plugin for accessing the Securosys Primus HSM or CloudsHSM.

Required attributes:

auth - Attribute defines the authorization type to TSB. Values for this attribute can be TOKEN, CERT or NONE
restapi - REST API URL to access the REST/TSB endpoint (available from your Security Officer or CloudsHSM service provider)

Define additional attributes based on the selected authorization type auth:

TOKEN Add the attribute bearertoken with the JWT token
CERT Setup certpath with local PATH to the certificate and keypath with local PATH to the key.
NONE No additional attributes required.

Command to write the configuration to the plugin

$ vault write securosys-hsm/config {config_attributes}

curl --location --request PUT '<server_addr>/v1/securosys-hsm/config' \
--header 'X-Vault-Token: <vault_access_token>' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode '{config_attribute_key}={config_attribute_value}' \

Example for disabled authorization:

$ vault write securosys-hsm/config 
auth="NONE" 
restapi="https://primusdev.cloudshsm.com"

curl --location --request PUT '<server_addr>/v1/securosys-hsm/config' \
--header 'X-Vault-Token: <vault_access_token>' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'auth=NONE' \
--data-urlencode 'restapi=https://primusdev.cloudshsm.com'

Example for JWT token authorization:

$ vault write securosys-hsm/config 
auth="TOKEN" 
bearertoken="jwt token string"
restapi="https://primusdev.cloudshsm.com"

curl --location --request PUT '<server_addr>/v1/securosys-hsm/config' \
--header 'X-Vault-Token: <vault_access_token>' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'auth=TOKEN' \
--data-urlencode 'bearertoken=jwt token string' \
--data-urlencode 'restapi=https://primusdev.cloudshsm.com'

Example for Certificate authorization:

$ vault write securosys-hsm/config 
auth="CERT" 
certpath="local_absolute_path_to_certificate.pem"
keypath="local_absolute_path_to_private.key"
restapi="https://primusdev.cloudshsm.com"

curl --location --request PUT '<server_addr>/v1/securosys-hsm/config' \
--header 'X-Vault-Token: <vault_access_token>' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'auth=CERT' \
--data-urlencode 'certpath=local_absolute_path_to_certificate.pem' \
--data-urlencode 'keypath=local_absolute_path_to_private.pem' \
--data-urlencode 'restapi=https://primusdev.cloudshsm.com'

Note: On any changes of the configuration, the plugin will try to reach out the defined TSB using the provided configuration. If the connection was successful, the plugin will write/overwrite the configuration, otherwise the previous configuration remains unchanged.

MetaData signature

From version 1.2.0

Additionally there is a option to generate signature for metadata on all asynchronous requests. applicationKeyPair option is using to provide RSA public key and private key. Using this key will be generated signature for metadata. format '{\"privateKey\":\"private_key_string\",\"publicKey\":\"public_key_string\"}'

Note: You have to provide private key and public key without headers

Example:

$ vault write securosys-hsm/config 
auth="CERT" 
certpath="local_absolute_path_to_certificate.pem"
keypath="local_absolute_path_to_private.key"
restapi="https://primusdev.cloudshsm.com"
applicationKeyPair="{\"privateKey\":\"MIIEvgIBADANBg...\",\"publicKey\":\"MIIBIjANBgkqh...\"}"

TSB ApiKeys

From version 1.2.0 Secrets engine use only 3 of TSB api keys:

ServiceToken - for health check
KeyManagementToken - for creating/listing/deleting keys
KeyOperationToken - for operations on keys like decrypt/encrypt, sign/verify etc.

Structure for api keys: There is a option to provide multiple api keys per single token. Plugin will check witch one of the list is correct one, and use only working token for operation.

apiKeys="{\"KeyManagementToken\":[\"tsb-x-token_key_management1\",\"tsb-x-token_key_management2\",\"tsb-x-token_key_management3\" ...],\"KeyOperationToken\":[\tsb-x-token_key_operation\"],\"ServiceToken\":[\"tsb-x-token_service\"]}"

Plugin configuration with api keys:

$ vault write securosys-hsm/config 
auth="CERT" 
certpath="local_absolute_path_to_certificate.pem"
keypath="local_absolute_path_to_private.key"
restapi="https://primusdev.cloudshsm.com"
apiKeys="{\"KeyManagementToken\":[\"tsb-x-token_key_management\"],\"KeyOperationToken\":[\tsb-x-token_key_operation\"],\"ServiceToken\":[\"tsb-x-token_service\"]}"

Manage Keys

The plugin allows to create, modify, and manage keys on the Securosys Primus HSM or CloudsHSM by the following command sets:

list - List all keys stored in the HSM

$ vault list securosys-hsm/keys_hsm

curl --location --request LIST '<server_addr>/v1/securosys-hsm/keys_hsm' \
--header 'X-Vault-Token: <vault_access_token>'

list - List all keys stored in the Secrets Engine

$ vault list securosys-hsm/keys

or for more a more detailed list

$ vault list -detailed securosys-hsm/keys

curl --location --request LIST '<server_addr>/v1/securosys-hsm/keys' \
--header 'X-Vault-Token: <vault_access_token>'

list key versions - List all key versions stored in the Secrets Engine

$ vault list securosys-hsm/keys/{key-name}

or for a more detailed list

$ vault list -detailed securosys-hsm/keys/{key-name}

curl --location --request LIST '<server_addr>/v1/securosys-hsm/keys' \
--header 'X-Vault-Token: <vault_access_token>'

read - Read stored key info like key label, policy or public key

$ vault read securosys-hsm/keys/{key-name}

curl --location --request GET '<server_addr>/v1/securosys-hsm/keys/{key-name}' \
--header 'X-Vault-Token: <vault_access_token>'

Result of this command will be

Key           Value
---           ---
algorithm     {key-type}            //For example: RSA, AES etc.
attributes    {key-attributes}
key_size      {key-size}
keyLabel      {key-label-hsm}
policy        {policy}              //If exists
public_key    {public-key-from-hsm} //If exists. Only in asymetric key
curveOid      {cureveoid}           //If exists. Only in EC or ED algorithms
...

write - Create or update a key on the HSM and store the reference in Secrets Engine Available key types:

aes

NOTE: All fields are described in Appendix: Key Arguments

IMPORTANT: All keys created via Secrets Engine, have by default set the key attributes [destroyable] and [modifiable]. These attributes can be changed or extended by defining them in the attributes argument.

$ vault write securosys-hsm/keys/{key-type}/{key-name} 
keyLabel="{key-label-hsm}"
keySize={key-size} 
#{key-attriute}:{true/false}
attributes='{"decrypt": true,"sign": false,"unwrap": true,"derive": true,"sensitive": true,"extractable": false,"modifiable": true,"copyable": false,"destroyable": true}'

curl --location --request PUT '<server_addr>/v1/securosys-hsm/keys/{key-type}/{key-name}' \
--header 'X-Vault-Token: <vault_access_token>' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'keyLabel={key-label-hsm}' \
--data-urlencode 'keySize={key-size}' \
--data-urlencode 'attributes={

Or here an example creating a key with attached simple approval policy:

$ vault write securosys-hsm/keys/{key-type}/{key-name} 
keyLabel="{key-label-hsm}"
keySize={key-size} 
#{key-attriute}:{true/false}
attributes='{"decrypt": true,"sign": false,"unwrap": true,"derive": true,"sensitive": true,"extractable": false,"modifiable": true,"copyable": false,"destroyable": true}'

Where simplePolicy has to be a JSON object in which Key is the name of the approval (or the approver) and Value has to be a valid RSA public key (without the "-- Begin..." and "-- End..." lines nor line breaks).

The result of these commands will show information about the created key.

NOTE: Full SKA policy json can be provided by using the policy attribute in place of simplePolicy. As a policy json statement can be very large it might be difficult to edit it on command line. In such case it is recommended to attach a file with the json, using the attribute "policy=@file.json". An example of the policy json file can be found in Appendix: Full Policy JSON Example

Requests

In case a key has an SKA policy attached, a request object is returned instead of an instant result response, indicating the required approvals to be collected to process this request.

For example:

Key                 Value
---                 -----
approvedBy          map[]
executionTime       n/a

etc.

To handle such requests there are the following additional commands:

list - List all requests initialized in Secrets Engine

$ vault list securosys-hsm/requests

or for a more detailed list

$ vault list -detailed securosys-hsm/requests

curl --location --request LIST '<server_addr>/v1/securosys-hsm/requests' \
--header 'X-Vault-Token: <vault_access_token>'

read - Show detailed request information

$ vault read securosys-hsm/requests/{id}

curl --location --request GET '<server_addr>/v1/securosys-hsm/requests/{id}' \
--header 'X-Vault-Token: <vault_access_token>'

delete - Remove a request from Secrets Engine and HSM

$ vault delete securosys-hsm/requests/{id}

curl --location --request DELETE '<server_addr>/v1/securosys-hsm/requests/{id}' \
--header 'X-Vault-Token: <vault_access_token>'

Additional Command Options

All Securosys Secrets Engine commands have the additional options:

-field (string: "") - Print only the field with the given name. Specifying this option will take precedence over other formatting directives. The result will not have a trailing newline making it ideal for piping to other processes.
-format (string: "table") - Print the output in the given format. Valid formats are "table", "json", "yaml", or "raw". This can also be specified via the VAULT_FORMAT environment variable.

Help

The command path-help will print help information of a specific path

$ vault path-help {path}

Test Suite

This plugin contains prepared tests written in Golang, which can be used to test changes or all features with the used Securosys Transaction Security Broker (TSB) instance.

Preparing

First adapt the test configuration file additional_test_config.go

var configParams map[string]interface{} = map[string]interface{}{
	"restapi":     "TSB_ADDRESS",
	"auth":        "TOKEN",
	"bearertoken": "BEARER_TOKEN",
}

Provide all necessary information in the test configuration file to gain access to the REST/TSB instance of your HSM. See Configuration section.

Running tests

To run all tests execute the following command in a terminal

$ go test -timeout 30m -run ^(TestOperationsEncrypt|TestOperationsSign|TestOperationsWrap|TestConfig|TestAESKey|TestBLSKey|TestCHACHA20Key|TestCamelliaKey|TestECKey|TestEDKey|TestIMPORTKey|TestRSAKey|TestTDEAKey|TestDSAKey|TestOperationsDecrypt|TestOperationsVerify|TestOperationsUnWrap|TestRequests|TestRotateKeys|TestCreateKeyUsingTypeName)$ secretengine

Integrations

MariaDB

Encryption on MariaDB can be enabled using existing plugin Hashicorp Key Management Plugin This integration stores generated secret in Secrets engine, encrypted by provided key. Supported Key Types/Algorithm combinations:

Key Type	Algorithm
RSA	RSA_PADDING_OAEP_WITH_SHA512 RSA RSA_PADDING_OAEP_WITH_SHA224 RSA_PADDING_OAEP_WITH_SHA256 RSA_PADDING_OAEP_WITH_SHA1 RSA_PADDING_OAEP RSA_PADDING_OAEP_WITH_SHA384 RSA_NO_PADDING
AES	AES_GCM AES_CTR AES_ECB AES_CBC_NO_PADDING AES
CHACHA20	CHACHA20 CHACHA20_AEAD
CAMELLIA	CAMELLIA CAMELLIA_CBC_NO_PADDING CAMELLIA_ECB
TDEA	TDEA_CBC TDEA_ECB TDEA_CBC_NO_PADDING

Note - Plugin supports asynchronous decrypt operation using key type RSA with policy with setup ruleUse. Using the key with policy will stop the decrypt operation and wait for approvals to be collected.

There are a serval steps that is needed to be done before setup encryption on MariaDB

Create / Register key into Secrets Engine

Generate new secret and encrypt it using stored key

$ vault write securosys-hsm/integrations/mariadb/{secret-name}     
keyName={key-name-from-secret-engine}
cipherAlgorithm={cipher-algorithm}
[additionalAuthenticationData={additional-authentication-data}]
[tagLength={tag-length}]
[password={password-for-a-key}]

curl --location --request PUT '<server_addr>/v1/securosys-hsm/integrations/mariadb/{secret-name} ' \
--header 'X-Vault-Token: <vault_access_token>'
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'keyName={key-name-from-secret-engine}' \
--data-urlencode 'cipherAlgorithm={cipher-algorithm}' \
--data-urlencode 'tagLength={tag-length}' \
--data-urlencode 'additionalAuthenticationData={additional-authentication-data}' \
--data-urlencode 'password={password-for-a-key}'

Note - Every request on this endpoint using same key name and secret name will rotate secret

The last step is add this configuration to my.cfg

[mariadb]
plugin-load-add=hashicorp_key_management.so
loose-hashicorp-key-management
loose-hashicorp-key-management-vault-url="{vault_address}/v1/securosys-hsm/integrations/mariadb/{secret_name}/?key_name={key-name}&cipher_algorithm={cipher_algorithm}&tag_length={tag_length}&aad={additional_authentication_data}&password={password}&version="
loose-hashicorp-key-management-token="{vault_access_token}"
loose-hashicorp-key-management-check-kv-version="off"
#max timeout is 86400 seconds

#Example of innodb config
innodb_encrypt_tables = ON
innodb_encrypt_temporary_tables = ON
innodb_encrypt_log = ON
innodb_encryption_threads = 4
innodb_encryption_rotate_key_age = 1

Note - In loose-hashicorp-key-management-vault-url url need to ends with &version=. Plugin from MariaDB automatically add to end of url number of secret version

MariaDB usage example

This example using default configuration for Hashicorp Vault dev server.

Frequently Asked Questions

I got the error 'no handler for route "securosys-hsm/...". route entry found, but backend is nil.' In case of no handler for route "securosys-hsm/...". route entry found, but backend is nil. error, try to replace the secrets engine binary and to register the new upgraded plugin. See How to run > Upgrade plugin
Why I don't get a public key and policy on some key types Some key types are symmetric, and therefore don't have a public key nor a SKA policy.
I have an error on unwrapping a key - status: 500, body: {"errorCode":701,"reason":"res.error.in.hsm","message":"Error unwrapping key"} Probably the provided key label is already in use with another key on the HSM, or the request contains a policy for a symmetric key.

Key Arguments

keyLabel: The created key will be stored on the HSM with this name. This parameter is required.

attributes: The attributes of the key that should be created. At least one cryptographic operation (decrypt, sign, unwrap) must be allowed (true). This parameter is required.

Available key attributes:

encrypt - The key can be used to encrypt data.
decrypt - The key can be used to decrypt data.
verify - The key can be used to verify signatures.
sign - The key can be used to create signatures.
wrap - The key can be used to wrap another key.
unwrap - The key can be used to unwrap keys.
derive - The key can be derivable. default: false
bip32 - Key derivation is done using BIP32. This option can only be true if the key's algorithm is EC and the derive attribute is true. default: false
extractable - The key is extractable. This option can only be true for keys without smart key attributes. default: false
modifiable - The key can be modified. default: true
destroyable - The key can be deleted. default: true
sensitive - The key is sensitive. To export a key sensitive must be false
copyable - The encrypted key is stored in an external memory. default: false

Structure Allows to define the attributes as a JSON object. Key = Value structure. For example:

{
  "decrypt": true,
  "sign": true,
  "unwrap": true,
  "derive": true,
  "modifiable": true,
  "copyable": false,
  "destroyable": true
}

curveOid: The oid of the curve used for the EC or ED algorithm. Mandatory if the chosen algorithm is set to EC or ED. Sample OID's: secp256k1=1.3.132.0.10, Ed25519=1.3.101.112, secp384r1=1.3.132.0.34, (prime256v1 / secp256r1): 1.2.840.10045.3.1.7

keySize: The length of the key. Only applicable for AES, Camellia, RSA , DSA.

policy: Defines the SKA policy of a key. Contains the rules to use this key for signing a payload in a sign request, the rules to block and unblock this key, and the rules to modify the policy of this key. If a rule is empty the associated operation can be performed without any approvals. If the policy is empty the key does not use smart key attributes, and it is not possible to add them later. If a policy is used with the key, the key cannot be exported. Structure Allows to define all required approvals as a JSON object. Key = Value structure.

For example:

{
  "TM": public_key_1,
  "WK": public_key_2,
}
