I noticed some "oddities" (to me) with the selection of a hash algorithm
by GnuPG. I assume that the particular use-cases have additional
limitations which are not obvious to me, so could you please clarify?
First, when sending a signed email from Evolution, SHA1 seems to be
chosen, no matter what "personal-digest-preferences" or even
"digest-algo" is set in the gpg.conf file (other parts of gpg.conf are
Is this a limitation of the PGP/MIME standard that Evolution uses?
Second, when using the smartcard, and "personal-digest-preferences
SHA256 RIPEMD160", the latter is chosen as digest algorithm.
Is the smartcard limited to 160 Bit hashes?
Talking about the smartcard...
Any news regarding a 2048 bit version? ;-)
Thanks for your insights,
