• Comprehensive Toolset: Offering a wide array of functionalities ranging from basic arithmetic operations to advanced cryptographic protocols.
• Cross-Platform: Written in C & Python, SECP256k2 is designed to be used on multiple operating systems including Windows and Linux & Mac.

Getting Started

Installation

windows with pip

pip install --upgrade secp256k2

linux and Mac with pip3

pip3 install --upgrade secp256k2

Generate and Converet 10,000 Key to Compress and Uncompress Address. ( Check Now in Google Colab )

import os, timeit

setup_code = """
from os import urandom
from secp256k2 import Contactor

cont = Contactor()

def test_Profile_1():
    numd = urandom(32)[0]
    caddr = cont.privatekey_to_address(0, True, numd)
    uaddr = cont.privatekey_to_address(0, False, numd)
"""

# // Total Generated 
num = 10000

time1 = timeit.timeit("test_Profile_1()", setup=setup_code, number=num)


print(f"Generated & Convereted {format(num, ',')} Key To : {time1:.6f} sec")

Note

Output : Generated & Convereted 10,000 Key To : 0.393369 sec

Usage

A quick example to get you started with SECP256k2:

from secp256k2 import Contactor

cont = Contactor()

dec = 0x00000000000000000000000000000000000000000000001

wif_compress = cont.Decimal_To_Wif(dec, True)

wif_uncompress = cont.Decimal_To_Wif(dec, False)

compressed and uncompressed bitcoin address wallet from decimal (integer).

from secp256k2 import Contactor
# added Contactor class to project script
co = Contactor()
# dec
dec = 0xffffffffffffffffffffff880000000000000
compress_address = co.Decimal_To_Addr(dec, addr_type=0, compress=True)
uncompress_address = co.Decimal_To_Addr(dec, addr_type=0, compress=False)

Convert Decimal (Number) To Ethereum Address (Maximum Range: 115792089237316195423570985008687907852837564279074904382605163141518161494337):

from secp256k2 import Contactor

cont = Contactor()

dec_num = 1 # example , can use any range number to 
# ethereum address generated from decimal number 
eth_address = cont.Decimal_To_ETH_Addr(dec_num)

convert and Generated Wif Key from decimal Number:

from secp256k2 import Contactor

co = Contactor()

dec = 0xffffffffffffffffffffffffff8999999999333666666
wif_compress = co.Decimal_To_Wif(dec, True)
wif_uncompress = co.Decimal_To_Wif(dec, False)

---

Decimal to RIPEMD160

from secp256k2 import Contactor

co = Contactor()

dec = 0xfffffffffffffffffff99999999999

ripemd160 = co.Decimal_To_RIPEMD160(dec)

---

convert wif key to private key (hex):

from secp256k2 import Contactor

co = Contactor()

WIF = "WIF_KEY_HERE"

privatekey = co.Wif_To_Hex(WIF)

Convert Private Key To Wif Compressed and Uncompressed

from secp256k2 import Contactor

cont = Contactor()

privatekey = "PRIVATE_KEY_HERE"

wif_compress = cont.btc_pvk_to_wif(privatekey, True)

wif_uncompress = cont.btc_pvk_to_wif(privatekey, False)

Convert Wif to Private Key (integer/decimal):

from secp256k2 import Contactor

cont = Contactor()

wif = "WIF_KEY_HERE"

privatekey = cont.btc_wif_to_pvk_int(wif)

Convert Wif to Private Key (hex):

from secp256k2 import Contactor

cont = Contactor()

wif = "WIF_KEY_HERE"

privatekey = cont.btc_wif_to_pvk_hex(wif)

Convert Private Key (decimal) To RIPEMD160 (h160)

from secp256k2 import Contactor

cont = Contactor()

privatekey = 12345678901234567891234567891234567789

ripemd160 = cont.privatekey_to_h160(privatekey)

Convert Private Key (Decimal) To Compressed and uncompressed Address

• addr_type (int) : P2PKH = 0, P2SH = 1, P2WPKH = 2
• compress (bool) : True : Compress, False : Uncompress
• private key (decimal) : 0 - 115792089237316195423570985008687907852837564279074904382605163141518161494337

from secp256k2 import Contactor

cont = Contactor()

privatekey = 12345678901234567891234567891234567789

address_compress = cont.privatekey_to_address(0, True, privatekey)

address_uncompress = cont.privatekey_to_address(0, False, privatekey)
