Python 中RSA的用法 使用pyOpenssl 生成RSA密钥对, 使用rsa 加解密

1. pyOpenSSL 生成RSA密钥对, 效率比较高
2. rsa 加解密方法简单
3. 代码import rsa
import base64

from OpenSSL.crypto import PKey
from OpenSSL.crypto import TYPE_RSA, FILETYPE_PEM, FILETYPE_ASN1
from OpenSSL.crypto import dump_privatekey, dump_publickey

pk = PKey()
pk.generate_key(TYPE_RSA, 512)
pub = dump_publickey(FILETYPE_PEM, pk)
pri = dump_privatekey(FILETYPE_ASN1, pk)

pubkey = rsa.PublicKey.load_pkcs1_openssl_pem(pub)
prikey = rsa.PrivateKey.load_pkcs1(pri, 'DER')

print(pubkey.save_pkcs1())
print(prikey.save_pkcs1())

data = rsa.encrypt(b'hello', pubkey)
data = base64.b64encode(data)

print(data)

data0 = rsa.decrypt(base64.b64decode(data), prikey)
print(data0)
