gpg 1.2.4
PGP 8.0

Description

When exporting a private key (made in PGP 8.0) to gpg 1.2.4. a string of error messages was produced.
missing primary user id, probably due to missing self-signatures. This could be due to PGP and not interesting for gpg users/developers.
key is unusable, unknown algo 254 - this apparently occurs when keys generated in newer versions are used in older versions. However, it is not supposed to occur between these two apps.

Fix

when exporting the secret key from gpg, add the option
--simple-sk-checksum. This will let gpg use the old but insecure key protection format. Newer pgp versions should understand that format too. See the manual.
