Question OpenPGP - MDC Packet - SHA1


OpenPGP Standard RFC 4880, not really a Linux Question, but as may be using GnuPG on Linux I thought I would ask here

The Modification Detection Code Packet is defined to use SHA-1, even though it does state in section 13.11. that this can be altered, and gives example methods. However this would cause interoperability, (q1)so I assume there is no standard method of doing this??

(q2)How much of a threat do you believe this to be? Even though the SHA-1 hash is encrypted within the symmetrically encrypted integrity protected data packet.


Cheers

Thomas
