PGP : what to do when a user ID has multiple RSA keys
My DOS version of PGP 2.6.2 came with a built in PUBRING.PGP containing two keys ( 1024 and 512 size ) with the same user ID . For testing purposes I wanted to encrypt a message with the 512 length key , but only the 1024 size key could be used . How can I select the right key , apart from making a clone PUBRING.PGP with only the key I want to use ? Any comment welcome

You can specify by the keyid. Do a pgp -kvv: $ pgp -kvv cmca@alpha.c2.org Type bits/keyID Date User ID pub 1024/6C87FFA5 1996/02/06 Chris McAuliffe <cmca@alpha.c2.org> 1 matching key found. Now do the encryption $ pgp -e 0x6C87FFA5 file Note the '0x' prefix on the keyid Chris McAuliffe <cmca@alpha.c2.org> (No, not that one.) -----BEGIN PGP SIGNATURE----- Version: 2.6 iQCVAwUBMUS+3IHskC9sh/+lAQF8jgP+LdUjgTnfv5k4KsOwEuvPmVsw/V/G3jdD pyNwOQNtytjSDcGBobspmU4rcx1DObToitJqjzr74G1ytGkrr4wHRS4FWIy3Ea3U YgrmEhkviJT7B4Ix/vQcrKZJsn2+ZGML6VyVmWr3ehkEMo20UfjIheeTNUSq2OPL rO9LmZiFyhs= =MSju -----END PGP SIGNATURE-----
