How to change the cipher used for encryption?

Hi,

I am using PGP command line 6.5.8 to encrypt files. It works fine, but it uses IDEA cipher. How can i change it to some other like 3DES, Blowfish, etc?
Thanks

why do you want to change it?

I don't think you can use any other 3des capable tool to decrypt pgp messages even if they are encrypted with 3des.

If your partners don't want to pay for pgp you can still take the trial desktop edition, after the trial period it converts to the free version (with reduced function set) or you use gpg, a free opensource counterpart.

I encrypted a file using the command line tool using the user's public key and signed it. But they could not decrypt it saying it was using the cipher IDEA. And asked me to change it to 3DES, blowfish, etc.
