Apparently you also need to add the option --no-openpgp, as mcrypt otherwise expects input in the OpenPGP format. $ mcrypt -a enigma -o scrypt --bare --decrypt --no-openpgp < /tmp/test Enter passphrase: testing Stdin was decrypted. I don't know if this behavior is controlled by a configure option and also could not spot any difference in a quick comparison with the Debian package. No idea what what causes this. Rainer
