openssl encryption and decryption,

encrypt
      openssl enc <cipher> -e -in filename.txt -out filename.enc
      openssl enc -aes-256-cfb -e -in filename.txt -out filename.enc


decrypt
      openssl enc <cipher> -d -in filename.enc -out filename.txt
      openssl enc -aes-256-cfb -d -in filename.enc -out filename.txt
