Hello,
I was wondering if anyone could help me with the MIC-Info and
Key-Info fields. The application I'm writing does not decrypt RIPEM
correctly. The problem lies in both of these fields.
Basically, I'm working on the assumption that to encrypt these
fields, you just
a) make the DEK (8 byte array for DES-CBC)
b) encrypt using the recipient's public key
c) print it as ascii encoded HEX values
But, RFC1423 seems to say that you
a) make the DEK
b) encode it with 0x00 || BT || PS || 0x00 || D
0x02 random dek
c) encrypt it sing the recipient's public key
d) print it out
or, b and c might be switched
But, RIPEM doesn't seem to work with any of these. Do I have to break up
the DEK into smaller chunks first? I'M CONFUSED!!!!!! (and just a little
bit frustrated).
Thanks in advance,
Your confused new-born cypherpunk-wannabe,
Dave
