encrypt-file - encrypt/decrypt a file with DES3 and openssl
encrypt-file [ -f password_file ] [ -k ] file...
decrypt-file [ -f password_file ] [ -k ] file...
encrypt-file encrypts a file using the openssl(1) command line tool from the OpenSSL project.
It uses the Triple DES cypher for encrypting the file with a given password https://secure.wikimedia.org/wikipedia/en/wiki/Triple_DES.
-f <password file>read the password for encrypting/decrypting from the given file
-kkeep the original file. Usually the file to be encrypted/decrypted is removed upon sucessful encryption/decryption.
If no password file is specified the user is asked to enter one.
decrypt-file decrypts a file using the openssl(1) command line tool from the OpenSSL project.
Encrypt a file requesting for a password:
encrypt-file secret_file.txt
Decrypt a file and keep the original requesting the user for a password.
decrypt-file -k secret_encrypted.enc
Encrypt a file reading the password from ~/.secret-pass:
encrypt-file -f ~/.secret-pass myfile.csv

For encrypting and compressing the order must always be: compression first and encryption second, since the encryption process randomizes the input, thus making any latter attempt to compress the file futile.
