Hello experts,

I just received an S/MIME encrypted mail which I can not decrypt with 
gpgsm 1.9.22 this seems to be due to the fact that the used algorithm 
was a RC2. It seems that the sender userd Thinderbird as Mailclient.

Here is a part of the log:

4 - 2007-04-14 22:52:42 gpgsm[5444]: unsupported algorithm 
`1.2.840.113549.3.2'

Is this a bug, a feature, and is there a way how I can decrypt these 
mails? I use openSUSE 10.2 and KDE 3.5.6 with gpgsm 1.9.22

Thanks a lot for any hint
Michael
