We have a limit of about 100 somewhere.  If you use a lot of non-ascii
characters you may hit the limit due to the utf-8 encoding.  This is
not very likely, though.

I guess that PGP uses the patented IDEA algorithm to protect the key.
This is not supported.  The simplest workaround is to set the passphrase
to empty with PGP and set it again with GnuPG.  Change the passphrase
with GPG might also help; iirc, they don't use IDEA anymore for new
passphrases.


Salam-Shalom,
