Encrypt and decrypt file using openssl command line

You can encrypt and decrypt the file using openssl command line. Somehow you will need to encrypt your important file with a secret key.

Encrypt

openssl enc -aes-256-cbc -in [input_file] -out [output_file]

Then Enter 2 times your secret key (this should be hard to guess and don't loose it)

Decrypt

openssl enc -aes-256-cbc -d -in [input_file] > [output_file]

Then enter your secret key to decrypt the content !

Notice : should use a 10-char length secret with alpha nums and special characters
