Keys

 

Keys are used for XML signature and encryption. There are two predominant kinds of keys used in the current Web services security implementation:

In public key-based signature, a message is signed using the sender private key and is verified using the sender public key. In public key-based encryption, a message is encrypted using the receiver public key and is decrypted using the receiver private key. In secret key-based signature and encryption, the same key is used by both parties. While the current implementation of Web services security can support both kinds of keys, there are a few items to note:

There is an important distinction between Version 5.x and V6 and later applications. The information in this article supports V5.x applications only that are used with WebSphere Application Server V6.0.x and later. The information does not apply to Version 6 and later applications.
