I'm trying to use my old pgp keys with Gnupg via gpg2.
I've successfully imported the keys both public and secret from my old key ring.
I've just tried to decrypt a file but I have the following error.
me@ubuntu:~/Documents$ gpg2 -d test01 gpg: protection algorithm 1 (IDEA) is not supported
the other data for the keys come up.
Gnupg offers an explanation about patents (the IDEA patent isn't compatible with gnupg) and a remedy: both here, http://www.gnupg.org/faq/why-not-idea.html
I followed the instructions at the end of the link and imported the idea.c.gz files into ~/.gnupg and unzipped them (only one of them unzipped) and tried to ./configure.
This didn't work. I made a directory called cipher, moved the two files into it and tried the ./configure command again. The system couldn't find configure.
Can anyone help me, please?
