like this symmetric only to any password to any key, if the passphrase is known bash-3.00$ ls -l filename.txt - -rw-r--r-- 1 morten other 12 Sep 11 19:31 filename.txt bash-3.00$ cat filename.txt hello world bash-3.00$ file filename.txt filename.txt: ascii text bash-3.00$ gpg -c filename.txt bash-3.00$ ls -l filename.txt* - -rw-r--r-- 1 morten other 12 Sep 11 19:31 filename.txt - -rw-r--r-- 1 morten other 63 Sep 11 23:59 filename.txt.gpg bash-3.00$ gpg --decrypt filename.txt.gpg gpg: CAST5 encrypted data gpg: encrypted with 1 passphrase hello world gpg: WARNING: message was not integrity protected bash-3.00$ this is the easiest way and gives some security. There are options to enforce --cipher-algo AES256 http://gnupg.org/documentation/manuals/gnupg/CMS-Options.html#index-cipher_002dalgo-272 - --cipher-algo oid Use the cipher algorithm with the ASN.1 object identifier oid for encryption. For convenience the strings 3DES, AES and AES256 may be used instead of their OIDs. The default is 3DES (1.2.840.113549.3.7). like this gpg -c --cipher-algo aes256 filename.txt However decrypting a binary or ascii file to a certain key the result may be binarty or ascii armored like this gpg --encrypt --armor --recipient AAA651B filename.txt # AAA651B is example for the target key ID or if you are happy with a binary result, like this gpg --encrypt --recipient AAA651B filename.txt On my system it works easy, there are some videos on facebook and perhaps youtube also explaining this more, you will also need to sign it. sincerely yours, Morten 0x81802954 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (SunOS) Comment: For keyID and its URL see the OpenPGP message header iEYEARECAAYFAkqqyzQACgkQ9ymv2YGAKVTWKQCg9rFJFGEAh9/nYAlyHq1ZBuiL w6kAnAn8CBlelb7I04mxhoSjY5q6IyCp =Voii -----END PGP SIGNATURE----- _______________________________________________ Gnupg-users mailing list Gnupg-users@gnupg.org http://lists.gnupg.org/mailman/listinfo/gnupg-users
