problem loading rsa extension to use with 2.6.3i key (SOLVED)
Tue, 4 Jul 2000 13:43:56 +0100
As a followup to my earlier message, I've found that typing --version
shows all the algorithms whereas -h doesn't.
[admin@sysadm1 admin]$ gpg --version
gpg (GnuPG) 1.0.1

Cipher: 3DES, CAST5, BLOWFISH, TWOFISH
Pubkey: RSA, RSA-E, RSA-S, ELG-E, DSA, ELG
Hash: MD5, SHA1, RIPEMD160
However, when trying to use the key to sign a file:
[admin@sysadm1 admin]$ gpg --clearsign text.txt
gpg: protection algorithm 1 is not supported
gpg: no default secret key: unknown cipher algorithm
gpg: text.txt: clearsign failed: unknown cipher algorithm
I figured this out too.. it's because there was a passphrase on the
2.6.3i key when I imported it. It wasn't the error message documented,
but reading through the list archives I found various comments about
this sort of thing so tried it anyway.
