python实现kdf算法

以下是两种Python实现KDF算法的例子：

1. 使用RSA加密算法实现KDF

import base64
from Cryptodome.PublicKey import RSA
from Cryptodome.Cipher import PKCS1_v1_5

data = "cKK8B2rWwfwWeXhz"
public_key = "MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAM1xhOWaThSMpfxFsjV5YaWOFHt+6RvS+zH2Pa47VVr8PkZYnRaaKKy2MYBuEh7mZfM/R1dUXTgu0gp6VTNeNQkCAwEAAQ=="

rsa_key = RSA.import_key(base64.b64decode(public_key))
cipher = PKCS1_v1_5.new(rsa_key)
cipher_text = base64.b64encode(cipher.encrypt(data.encode(encoding="utf-8")))

print(cipher_text)

2. 使用PBKDF2算法实现KDF

import binascii
from Cryptodome.Hash import SHA1
from Cryptodome.Protocol.KDF import PBKDF2

def pbkdf2_encrypt(text, salt):
    result = PBKDF2(text, salt, count=10, hmac_hash_module=SHA1)
    result = binascii.hexlify(result).decode()
    return result

if __name__ == '__main__':
    text = 'PBKDF2'
    salt = b'123456'
    result = pbkdf2_encrypt(text=text, salt=salt)
    print(result)
