在开始讨论公钥私钥以及生成它们的基本原理之前，我想首先说明加密和数字签署XML数据的其他方法。

Before jumping into public and private keys and the nitty-gritty of generating them, I'd like to show you some other options for encrypting and digitally signing XML data.

从技术的角度来看，还可以使用各种加密方法来建立信任，包括加密密钥、私钥或公钥、数字签名，或者协议。

Trust is also established from a technology perspective using cryptographic methods, including encryption keys, private or public keys, digital signatures, or protocols.

对于PGP和其他公钥加密方法，不存在从公钥推断某人私钥的方法。

With PGP and other public-key encryption methods, there's no way to deduce someone's private key from the public key.
