非对称算法使用不同的密钥对消息进行加密或解密；其中一个秘钥必须是秘密的，而另一个密钥通常是公开的。
An asymmetric algorithm USES a different key for encrypting or decrypting the message; one of the keys must be kept secret, and the other key is usually made public.
数据块使用一个对称密钥算法进行加密，它使用一个密钥来实现对数据的加密和解密。
The bulk of the data is encrypted using a symmetric key algorithm that encrypts and decrypts data using a single secure key.
用于数据加密的密钥是使用带有与服务提供者（Service Provider）的 X.509证书相关联的公钥的非对称算法进行加密的。
The key used for the data encryption is encrypted itself using an asymmetric algorithm with the public key associated with the Service Provider's X.509 certificate.
首先为其建立索引，并使用对称的加密模式(例如aes)以唯一的密钥对其进行加密。
Begins by indexing it and encrypting it with a symmetric encryption scheme (e.g., AES) under a unique key.
从mastersecret中，客户机和服务器可以创建sessionkeys(会话密钥)，这是选择用来对会话数据进行加密所使用的对称密码中的对称密钥。
From the master secret, the client and server create the session keys, symmetric keys within the bounds of the chosen symmetric cipher used to encrypt the session's data.
从客户端将消息发送到网络之前，WS-Security使用了非对称密钥对消息进行数字签名和加密。
Prior to the message being sent onto the wire from the client, WS-Security used asymmetric keys to digitally sign and encrypt the message.
这些结果表明使用客户端生成的密钥进行WS - Security对称加密几乎和WS - SecureConversation一样快，特别是对于较大的消息。
These results show that WS-Security symmetric encryption with client-generated keys is nearly as fast as WS-SecureConversation, especially for larger messages.
使用不对称加密和public/private密钥对进行消息的签名和加密是很简单的（至少概念上很简单）。
Using asymmetric encryption with public/private key pairs for signing and encrypting messages is simple (at least conceptually!).
SymmEncr：需要使用一个客户端生成您的密钥进行对称加密。
SymmEncr: Require symmetric encryption using a client-generated secret key.
换言之，可以同时使用多个证书、密码、对称密钥以及非对称密钥对单个对称密钥进行加密。
In other words, a single symmetric key can be encrypted by using multiple certificates, passwords, symmetric keys, and asymmetric keys at the same time.
