在本章中,我们将重点介绍RSA密码加密的不同实现及其涉及的功能。您可以引用或包含此Python文件以实现RSA密码算法实现。
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。我们将使用以下代码使用一个函数来生成新密钥或一对公钥和私钥。
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,使用以下函数,该函数遵循RSA算法-
def encrypt(message, pub_key):
cipher = PKCS1_OAEP.new(pub_key)
return cipher.encrypt(message)
两个参数是必需的: message和pub_key ,它指的是公钥。公钥用于加密,私钥用于解密。
下面提到了完整的加密程序程序-
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"
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)
def getpublickey(priv_key):
return priv_key.publickey()
def encrypt(message, pub_key):
cipher = PKCS1_OAEP.new(pub_key)
return cipher.encrypt(message)
