2. 通过模和指数获取到证书PEM(方法见:https://www.cnblogs.com/luo30zhao/p/10515594.html)。 3. 通过保存的PEM证书,进行rsa加密后认证。如下: #读取证书 with open('pub_key.pem', 'r') as f: #pubkey = rsa.PublicKey.load_pkcs1_openssl_der(f.read()) pubkey = rsa.PublicKey.load_pkcs1_o...

1. 2. 3. 4. 在这段代码中,我们使用rsa.newkeys()函数生成了一个1024位的RSA密钥对,并将公钥和私钥分别存储在pubkey和privkey变量中。 2. 加密数据 使用公钥对数据进行加密。下面是一个示例代码: importrsa# 加载公钥pubkey=rsa.PublicKey.load_pkcs1_openssl_pem(pubkey_str)# 加密数据encrypted_data=rsa....
pubkey = rsa.PublicKey.load_pkcs1_openssl_pem(public_key) crypto = b'' divide = int(len(message) / 117) divide = divide if (divide > 0) else divide + 1 line = divide if (len(message) % 117 == 0) else divide + 1 for i in range(line): ...
$ openssl rsautl-sign-in1.txt-inkey pri2048.pem-out1.bin ${echo1.bin;echo pub2048.pem;}|./test_rsa.py Just a test 一切OK,注意,公钥pem从私钥里析出必须用-RSAPublicKey_out,这样pem文件的第一行和最后一行为以下,这样rsa.PublicKey.load_pkcs1才会认识。
另外Python本身也连接了OpenSSL作为其他用途,这两者一般不会有冲突.万一有冲突了可以参考这里进行解决: Installation - Cryptography 43.0.0.dev1 documentationcryptography.io/en/latest/installation/ 生成/保存/载入密钥 defgenerate_save_or_load(length:int)->Tuple[object,object]:private_key_file_pem_name="...

调试输出一下,看类型,是否可以用str()转换一下.
