接下来,我们可以使用以下代码示例读取PEM文件中的公钥: fromcryptography.hazmat.backendsimportdefault_backendfromcryptography.hazmat.primitivesimportserialization# 读取PEM格式的公钥文件defload_public_key(pem_file_path):withopen(pem_file_path,'rb')aspem_file:pem_data=pem_file.read()public_key=serialization.l...

基于非对称算法的RSA Key主要有两个用途,数字签名和验证(私钥签名,公钥验证),以及非对称加解密(公钥加密,私钥解密)。本文提供一个基于OpenSSL和Python进行非对称加解密的例子。 1. OpenSSL实现非对称加解密 1.1 生成私钥,并导出公钥 生成2048 bit的PEM格式的RSA Key:Key.pem ...
