Hi again, :) The mcrypt source distribution includes a magic file which can be used with the 'file' tool to get the information about an encrypted file.
File with its default database also works quite well, so please try these two commands with the attached magic file saved to the same directory as one of your undecryptable files: $ file something FORMAT.nc: mcrypt 2.5 encrypted data, algorithm: rijndael-128, keysize: 32 bytes, mode: cbc, $ file -m magic something FORMAT.nc: mcrypt 2.5 encrypted data, algorithm: rijndael-128, keysize: 32 bytes, mode: cbc, key generator: mcrypt-sha1 You have to substitute something with your filename of course. Thanks, Gergely
