PGP (Pretty Good Privacy) 是一种加密通信协议,用于保护电子邮件和文件的安全性和隐私。它通过使用加密、数字签名和压缩技术来确保数据的保密性、完整性和可验证性。 GP最初由麻省理工学院的Nick embrace和Eric Hughes开发,后来由Phil Zimmermann进一步发展。它使用公钥加密和私钥解密的机制,以确保只有信息的接收者才能...

1.对称加密:PGP使用对称加密算法(如AES、3DES等)来加密邮件和文件的内容。对称加密使用相同的密钥用于加密和解密,速度较快,适合处理大量数据。 2.非对称加密:PGP使用非对称加密算法(如RSA、ECC等)来加密和解密对称密钥。发送方使用接收方的公钥加密对称密钥,接收方使用自己的私钥解密对称密钥。非对称加密提供了安全的...
