First of all thanks to you for jasypt, it indeed simplifies many of the chores on encryption for everyday usage.
In my current project one thing I need to do is to create keyed MACs or HMACs, in paticular SHA-1 HMAC as needed for example for OAuth http://oauth.net/core/1.0a
I couldn't find support for hmacs in javasypt but perhaps I'm not looking well enough. Would an hmac be the same as normal digestor with a given salt?
