Cancel-Lock for Gnus; changing to SHA2 possible?

Cancel-Lock for Gnus; changing to SHA2 possible?

[Peter Faust]

Hello together!

A few Gnus-users are interested in changing the cancel-lock from sha1:
to sha-256 or sha-512 for News/Postings with Gnus.

I found canlock.el for this function, and i hope someone can help me
to change this.

If this is not possible, please have a look at the following draft and
think about it, please:

I don't see why we couldn't switch the call to `sha1' to a call to
`secure-hash', which would allow for easily selecting between
algorithms.

Just out of curiosity: why do you have three different Cancel-Locks? I
thought there should be only two of them, one created by client and other
one created by injecting server.

Thats correct.

But i am using a local proxy named "Hamster" to pull News and Mails from
several Servers. And this proxy generates an additional cancel-lock.

In my post is one cancel-lock from Gnus, one from local proxy, and one
from my injecting Newsserver.

Greeting, Peter
