python简单的加密解密
rsa 是非对称加密
公钥加密，私钥解密
pip install rsa
import rsa
from binascii import b2a_hex, a2b_hex
class rsacrypt():
def __init__(self):
''''''
def encrypt(self, text):
#加密文本
self.ciphertext = rsa.encrypt(text.encode(),self.pubkey)
return b2a_hex(self.ciphertext)
def decrypt(self, text):
#解密文本
decrypt_text = rsa.decrypt(a2b_hex(text),self.prikey)
return decrypt_text
def create_key(self):
#获取一对秘钥
pubkey, prikey = rsa.newkeys(256)
pub = pubkey.save_pkcs1()
pri = prikey.save_pkcs1()
return (pub,pri)
def load_pub_key(self,pub):
#导入公钥，为加密准备
self.pubkey = rsa.PublicKey.load_pkcs1(pub)
def load_pri_key(self,pri):
#导入私钥，为解密准备
self.prikey = rsa.PrivateKey.load_pkcs1(pri)
