PGP / GnuPG Problems and Solutions

problem: have a pgp key, export from pgp but can't import to gpg.

    $ gpg --import somefile.pub
    gpg: key deadbeef: no valid user IDs
    gpg: this may be caused by a missing self-signature

solution: gpg --import --allow-non-selfsigned-uid somefile.pub

problem: have a file encrypted with the IDEA algorithm

          gpg does not include IDEA due to patent issues

solution: gnupg FAQ #3.3 - get the IDEA plugin

  notes:
    1)  compiling instructions are in the header of idea.c
    2)  if not building gnupg from sources, a good place for
        step #1 to take place is probably /usr/lib/gnupg.
    3)  each IDEA user needs a line in ~/.gnupg/options ...
