Specific v5 changes
Another thing I'd like to see changed in v5 is the incredibly annoying way
OpenPGP handles its PRF. For every PRF use on the planet except OpenPGP, you
specify the number of iterations of the PRF to be applied. For OpenPGP you
specify the number of bytes to output and then have to work backwards through
the PRF to figure out how many iterations this amounts to. Making things even
worse, the count is encoded in a weirdo fixed-point format that can't be
passed as an integer count parameter to anything because it's not, or
alternatively that if passed as an integer has to then be converted back into
its oddball fixed-point format when written. So:
Replace the S2K 'count' value with a 32-bit integer specifying the number of
PRF iterations to apply.
Peter.
