Openssl file encryption and decryption

ENCRYTPION
openssl aes-256-cbc -a -salt -in sensitive_doc.txt -out sensitive_doc.txt.enc

-a : base 64 encoding
-salt: makes it more secure
-in : unencrypted file
-out: encrypted file

DECRYPTION
openssl aes-256-cbc -d -a -in -in sensitive_doc.txt.enc -out sensitive_doc.txt.recovered
