HMAC secret key in keystore

[Jeroen Wolff]

Hi,

I want to get HMAC working on websphere 6 for WS-Security.
In the websphere docs i read:

WebSphere Application Server Versions 6 and later support a secret key-based signature called HMAC-SHA1. If you use HMAC-SHA1, the SOAP message does not contain a binary security token. In this case, it is assumed that the key information within the message contains the key name that is used to specify the secret key within the keystore.

How can i put a secret key in a keystore? I know how to generate keys with keytool, but
for this one we (client en server) need the same secret stored in the keystore...how do i do that?

Thanks,

Jeroen Wolff
