As I'm not a crypto-expert this is probably a stupid question, but, as far as 
I understand 1.2.840.113549.3.2 stands for the 40bit and the 128bit version 
of the rc2-algorithm, doesn't it? 
Why can't I decrypt a message sent from outlook express, though it complains 
that it can only encrypt using 40bit? 

Are there different RC2 (40bit)-Algorithms?
I found a list of crypto-algorithms with oid (what does this stand for?) and 
there's at least two versions of the rc2-algorithm:

1.2.840.113549.3.2    is called RC2CBC
1.2.840.113549. is called pbeWithSHA1And40BitRC2_CBC

What's the difference between these two?

Are both 40bit?

Is there any way to decrypt outlook-40bit-messages?

Now I recompiled everything and things are sort of working but not really 
- rc2 still doesn't work (s. above)
- encryption-capabilities seem not to be part of the signature-certificate (at 
least they aren't imported into the gpgsm-keybox (gpgsm --dump-keys doesn't 
show any after verifying a self-signed text) and outlook express still 
doesn't know how to encrypt mail it wants to send to me and encrypts using 
40bit rc2 (which I can't decrypt, s. above)
- signing and encryption takes very (!) long using kmail (sometimes several 
minutes). There seem to be thousands of gpgsm-instances started and 
immediately finished (can be seen using ps) until I get the gpg-agent-window 
to enter the passphrase. Is there a problem in the communication between 
kmail and gpgsm?

Thanks again for any help

got an answer, yet, so I put it all together in another email so that
