加密算法包含的模块如下
from Crypto.PublicKey import RSA from Crypto.Cipher import PKCS1_OAEP from Crypto.Signature import PKCS1_v1_5 from Crypto.Hash import SHA512, SHA384, SHA256, SHA, MD5 from Crypto import Random from base64 import b64encode, b64decode hash = "SHA-256"
为了更好的安全性,我们将哈希值初始化为SHA-256.我们将使用函数生成新密钥或一对公钥和私钥.
使用以下代码.
def newkeys(keysize): random_generator = Random.new().read key = RSA.generate(keysize, random_generator) private, public = key, key.publickey() return public, private def importKey(externKey): return RSA.importKey(externKey)
对于加密,在RSA之后使用以下函数algorithm:
def encrypt(message, pub_key): cipher = PKCS1_OAEP.new(pub_key) return cipher.encrypt(message)
两个参数是必需的:消息和 pub_key ,它指的是公钥.公钥用于加密,私钥用于解密.
