Is there maybe a well, googling for "encrypt .cpt" reveals, that there is a program called "ccrypt" which is ncrypting files and adding .cpt to the filename: http://quasar.mathstat.uottawa.ca/~selinger/ccrypt/ the website says "ccrypt is based on the Rijndael cipher" so *if* ccrypt was used to encrypt your file (crawl old SuSE distros for that program), then we should have the algorithm. > utility that would allow me to put in a password and have it try to > decrypt using all known algorithms and perhaps show the first few lines > from the decrypted file (so I can determine if one looks like a gz file the plaintext, i.e. the "gz" contents should only be available when you have the correct passphrase though...that's why it's encrypted ;-) Christian. - -- BOFH excuse #383: Your processor has taken a ride to Heaven's Gate on the UFO behind Hale-Bopp's comet. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFBanlb+A7rjkF8z0wRAjrpAJ9CtEBk/+EawIYppQr9fHKFywFGrQCeJWd4 iFeQTh56lgXcSp+xoLJx9Kc= =lHrz -----END PGP SIGNATURE----- - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
