[Dovecot] [PATCH] Generalize HMAC implementation

4 Sep 2012


      Hello everyone and Timo in particular,
about a year ago I implemented a SHA-1 variant of the HMAC(-MD5) present
in Dovecot.
I had always disliked this a bit, because it replicates a lot of code.
This patch generalizes the HMAC function to take a hash_method struct as
parameter, and changes existing code which uses the "old" HMAC function
to use this new one.
I'm not really sure this is actually a good idea, but I still felt I
should provide the code in case you would want to merge it upstream.
Attached is the patch as a hg export based on the revision of
dovecot-2.2 current at the time of writing.
Regards,
Florian Zeitz
