Comments:        It is based on the Rijndael block cipher, a version
                 of which is also used in the Advanced Encryption Standard 
                 (AES, see http://www.nist.gov/aes). This cipher is believed 
                 to provide very strong cryptographic security, ~ 11 years ago
                 2021, Redhat thinks it was secure as per
                 https://www.redhat.com/en/blog/encryption-and-decryption-ccrypt
                 See doc for more info. Below are my main ways......pw = password

                 Encrypt
                 $ ccencrypt filename
                 (input pw twice) -> filename.cpt

                 Decrypt
                 $ ccdecrypt filename.cpt
                 (input known pw)

                 forgotten key
                 #############
                 $ ccguess -K (input best guess pw)  filename.cpt 

                 eg ccguess -K lobe way2.png.cpt 
                 Generating patterns...1..2..3..4..5..sorting...done.
                 Possible match: love (1 change, found after trying 322 keys) 
                 But cpt file remains! 

                 This means is not absolutely secure but may help if you made 
                 a typo in creation, or a typo in unlocking.
                 Note that it appears to be strict with lower/upper case
                 so -K failed for me with a wrong case input.
