python rsa加密

rsa简单加密：

 1 import rsa
 2 import base64
 3
 4 rsa_key_pair = rsa.newkeys(2048)  # 生成密钥对，返回(PublicKey(n,e), PrivateKey(n,e,d,p,q))，即（公钥对象，私钥对象）
 5
 6 rsa_pubkey, rsa_privkey = rsa_key_pair
 7
 8 #加密
 9 text = "hello world"
10 crypto_text_e = base64.b64encode(rsa.encrypt(text.encode("utf-8"), rsa_pubkey))
11 print("加密内容：{}".format(crypto_text_e.decode()))
12
13 #解密
14 crypto_text_d = rsa.decrypt(base64.b64decode(crypto_text_e), rsa_privkey)
15 print("解密内容：{}".format(crypto_text_d.decode()))

base64.b64encode()，base64.b64decode() 返回类型都是bytes，打印时添加.decode()将bytes转为str.

输出：

rsa加载密钥：

rsa.PrivateKey.load_pkcs1(证书密钥-bytes类型, 证书格式-默认为”PEM“)  # Loads a key in PKCS#1 DER or PEM format.
