CIFRAR
El cifrado se realiza con CAST5
$ touch a $ gpg -c a Enter passphrase:elpasswordessecreto $ gpg: WARNING: `a' is an empty file $ ls -l -rw-r--r-- 1 root root 0 2010-12-04 00:00 a -rw-r--r-- 1 root root 40 2010-12-04 00:00 a.gpg |
DESCIFRAR
$ gpg a.gpg gpg: CAST5 encrypted data gpg: encrypted with 1 passphrase File `a' exists. Overwrite? (y/N) y gpg: WARNING: message was not integrity protected |
