Hi there,

I have a question reg. PGP:

If certain parts of an encrypted message are known, does that
compromise the security of the rest of the message?
Example: If I always use a signature file, in plaintext messages as
well as in encrypted messages, could an attacker knowing that
signature file to be part of my encrypted message crack the rest
too?

Please copy replies to my private e-mail, for I am currently not
subscribed to the CP list...

Thanks in advance for your help,

Harka
