python rsa-oaep加密的示例代码

代码：

from Crypto.PublicKey import RSAfrom Crypto.Cipher import PKCS1_OAEPimport base64rsa_key_pair = RSA.generate(1024)pubkey = rsa_key_pair.publickey().export_key()privkey = rsa_key_pair.export_key()print(pubkey.decode())print(privkey.decode())# 公钥加密text = 'hello world'rsa_pubkey = RSA.import_key(pubkey)cipher_pub = PKCS1_OAEP.new(rsa_pubkey)ciphervalue_enc = base64.b64encode(cipher_pub.encrypt(text.encode('utf-8')))print('加密内容:n{}'.format(ciphervalue_enc.decode()))#私钥解密rsa_privkey = RSA.import_key(privkey)cipher_priv = PKCS1_OAEP.new(rsa_privkey)ciphervalue_dec = cipher_priv.decrypt(base64.b64decode(ciphervalue_enc))print('解密内容:n{}'.format(ciphervalue_dec.decode()))

输出：
