No sodium for 7.2

[aolko]

apparently you don't need to apt install php7.2-sodium anymore oerdnj/deb.sury.org#747

https://kinsta.com/blog/php-7-2/

Starting from version 7.2, PHP includes the Sodium library into the core.

[Nenglish7]

You need to because libsodium is considered an option on install. Travis CI does not include it in their images. So if you use the built in libsodium function without manually installing with the Travis configuration, errors would pop up saying undefined function. travis-ci/travis-ci#8863

so that's the travis issue, otherwise this package is retired...at least for ondrej ppa (as linked in the first post)

The OS needs to include libsodium with PHP 7.2. Failure to do so is a sign that your OS vendor is asleep at the wheel regarding the PHP community.

[multiwebinc]

For Ubuntu/Debian the package is php-libsodium.

Nevermind. Do not install php-libsodium since this actually conflicts with the libsodium included in PHP. PHP 7.2 requires the libsodium23 package on Ubuntu.

does this make https://github.com/paragonie/halite/blob/master/doc/Install-Guides/Ubuntu.md redundant?

When I use the Ubuntu 16.04, add the ondrej/php repository.

And try to find php7.2-sodium and php7.3-sodium and they've been removed.

My executed commands are as follows:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-cache search php7.2-sodium
sudo apt-cache search php7.3-sodium

And the result is nothing to be presented.

lee@PowerEdge-R730:~$ sudo apt-cache search php7.2-sodium
lee@PowerEdge-R730:~$ sudo apt-cache search php7.3-sodium
lee@PowerEdge-R730:~$

What is the output of the following PHP script?

<?php
if (extension_loaded('sodium')) {
    $key = sodium_hex2bin('ba6d0a2309dc546d1131f4be04dfa14da9d7e8a5430f99b7446f4207405473d5');
    $nonce = sodium_hex2bin('94417152051bd43661f12dff58709b1566f052aba4fd7806');
    $c = sodium_hex2bin(
        'd2207e8651189c0b4d3a51d544f7811b51f899ca55a6dc0630e5c9dd262c34' . 
        'bb0af2fd248493899c3dfb007a2bc366faf300034a602bbe8b54d38df135dd' . 
        '2a70086f89c711e86d60e44ac1826909c4527c7f8cc55a3c4e45a79ae573da' . 
        '1c352ed618b3'
    );
    echo sodium_crypto_secretbox_open($c, $nonce, $key), PHP_EOL;
} else {
    echo 'Not loaded', PHP_EOL;
    exit(1);
}

@paragonie-scott, thanks for your reply. The result is available here after executing the code snippets you mention:

And the test.php contains the code snippets you mention.

lee@PowerEdge-R730:~$ php -v

PHP Fatal error:  Uncaught SodiumException: nonce size should be SODIUM_CRYPTO_SECRETBOX_NONCEBYTES bytes in /home/lee/test.php:11

lee@PowerEdge-R730:~$ 

Why? According to the sodium_crypto_secretbox_open function reference, it should be the sodium_crypto_secretbox_open ( string $ciphertext , string $nonce , string $key ) : string.

Your code snippets seem to be have the incorrect argument order. After exchanging the $nonce and $key, it presents following message:

lee@PowerEdge-R730:~$ php test.php
All is working as expected. Libsodium is installed in core, not a separate package.
lee@PowerEdge-R730:~$

Sodium is installed in php7.2 just check with:

php -m | grep sodium
=> sodium
