Huh... Wait a minute. You're encrypting it once and then encrypting it a second time. What are you trying to accomplish here? What happens when you do the following: gpg -a -z0 -c a cp a.asc a1.asc gpg a1.asc ls -l Encrypt a to a.asc. Copy the encrypted file to another file (because gpg will insist on decrypting it back to the base name minus the .asc). Decrypt the new encrypted file back to a new decrypted file. Compare them.

You have to load it as a module. Presuming that the module was installed when you instaled gpg, you should be able to add this to the .gnupg/options file: load-extension idea

Actually shouldn't make any difference. Mandrake is rpm based. Did you install it from RPM or build it yourself? Mike -- Michael H.
