python 实现RSA公钥加密,私钥解密
from Crypto.PublicKey import RSA from Crypto.Cipher import PKCS1_v1_5 as Cipher_pkcs1_v1_5 from Crypto.Signature import PKCS1_v1_5 as Signature_pkcs1_v1_5 import base64 # 私钥 private_key = '''-----BEGIN RSA PRIVATE KEY----- 5353dfggd -----END RSA PRIVATE KEY----- ''' # 公钥 public_key = '''-----BEGIN PUBLIC KEY----- hfgghftetet -----END PUBLIC KEY-----''' def rsa_encrypt(message): """校验RSA加密 使用公钥进行加密""" cipher = Cipher_pkcs1_v1_5.new(RSA.importKey(public_key)) cipher_text = base64.b64encode(cipher.encrypt(message.encode())).decode() return cipher_text def rsa_decrypt(text): """校验RSA加密 使用私钥进行解密""" cipher = Cipher_pkcs1_v1_5.new(RSA.importKey(private_key)) retval = cipher.decrypt(base64.b64decode(text), 'ERROR').decode('utf-8') return retval
注意:
从后台获取到的pubkey直接入参,会出现报错:ValueError:RSA key format is not supported
正确应该如下方式
def rsa_encrypt(password:str,publickey): """校验RSA加密 使用公钥进行加密""" public_key = '-----BEGIN PUBLIC KEY-----\n'+ publickey +'\n-----END PUBLIC KEY-----' cipher = Cipher_pkcs1_v1_5.new(RSA.importKey(public_key)) cipher_text = base64.b64encode(cipher.encrypt(password.encode())).decode() return cipher_text
