What are the interesting use cases for SHA-512? I guess it's getting more interesting as 64-bit machines are getting more common.
i've been issuing SHA-512-based OpenPGP certifications lately, partly to find out where i run into compatibility problems.
I'm also interested in making some OpenPGP tools, and exploring the range of crypto primitive toolkits to use. nettle seems like an obvious choice, but i won't be able to test those certs with it.
so: not a great or urgent reason, but it'd be nice to be able to use nettle as a basis for tools that implement higher-level specs.
I also haven't been following the NIST hash competition very closely, but whatever comes out of that process should be high on the wish list.
yes, agreed.
(i suppose the same question holds for the primitives in libhogweed that include a digest operation, such as RSA signing)
Adding support for new hashes there is easy, as soon as people have agreed on which object id to use.
what do you mean by object id?
My resend here is unsigned, but it would be nice to be able to send signed mails to the list!
Agree! I'm not sure how to fix it, maybe it's sufficient to add "multipart/signed" to mailman's pass_mime_types?
i don't know, but that sounds like a reasonable thing to try. let me know if you want me to test it.
