• python rsa-oaep加密示例


    代码:

     1 from Crypto.PublicKey import RSA
     2 from Crypto.Cipher import PKCS1_OAEP
     3 import base64
     4 rsa_key_pair = RSA.generate(1024)
     5 pubkey = rsa_key_pair.publickey().export_key()
     6 privkey = rsa_key_pair.export_key()
     7 print(pubkey.decode())
     8 print(privkey.decode())
     9 
    10 # 公钥加密
    11 text = "hello world"
    12 rsa_pubkey = RSA.import_key(pubkey)
    13 cipher_pub = PKCS1_OAEP.new(rsa_pubkey)
    14 ciphervalue_enc = base64.b64encode(cipher_pub.encrypt(text.encode("utf-8")))
    15 print("加密内容:
    {}".format(ciphervalue_enc.decode()))
    16 
    17 #私钥解密
    18 rsa_privkey = RSA.import_key(privkey)
    19 cipher_priv = PKCS1_OAEP.new(rsa_privkey)
    20 ciphervalue_dec = cipher_priv.decrypt(base64.b64decode(ciphervalue_enc))
    21 print("解密内容:
    {}".format(ciphervalue_dec.decode()))

    输出:
