Encrypt TripleDES


You want to encrypt some text, using the tripleDES Cipher.



Openssl is a beautiful command, that performs many functions. See example.



Openssl tripleDES encrypt command:
openssl des3 -salt -in file_to_encrypt -pass pass:_your_password_


Place contents to encrypt in the file reference by file_to_encrypt

Replace your_password with your secret

Openssl will output to stdout – so best to capture like this:
myvar=$(the openssl command)
Openssl tripleDES decrypt command:
openssl des3 -d -salt -in file_to_encrypt -pass pass:_your_password_
Put cipher text to decrypt in filename supplied to -in

Replace _your_password_ with the secret

Outputs to stdout
