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.
