python rsa加解密
一. Rsa加密
先去改网站生成rsa公私钥 http://web.chacuo.net/netrsakeypair
import base64
from Crypto.PublicKey import RSA
from Crypto.Cipher import PKCS1_v1_5 as Cipher_pkcs1_v1_5
public_key = """-----BEGIN PUBLIC KEY-----

"""
text = 'abcdefg'
a = bytes(msg, encoding="utf8")
rsakey = RSA.importKey(public_key)
cipher = Cipher_pkcs1_v1_5.new(rsakey)
cipher_text = base64.b64encode(cipher.encrypt(a))
print(cipher_text) # b'RkuzBbP1CyAQ1YuboLBwrxqUJdCM/HfIdfJiNJTDMmmwEDxn0VxQAd+l3lu17gaRtzYxrJtQ71ftExlDasOJUAFyMTqmshnl4TNjaKDLDkQ881lEEKLZPUjIVhuqUsMreCybQkeJyJsJZxZaL8AtUBEVZMG0Qz9jRCF25IUlFzg='
二. Rsa解密
import base64
from Crypto.PublicKey import RSA
from Crypto.Cipher import PKCS1_v1_5 as Cipher_pkcs1_v1_5
decodeStr = base64.b64decode(cipher_text) # cipher_text是上面rsa加密的内容
prikey = Cipher_pkcs1_v1_5.new(RSA.importKey(private_key))
encry_text = prikey.decrypt(decodeStr, b'rsa')
encry_value = encry_text.decode('utf8')
print(encry_value) # abcdefgh
