Ccrypt is a command line tool for encryption and decryption of data. Ccrypt is based on the Rijndael cipher, the same cipher used in the AES standard. On the other hand, in the AES standard, a 128-bit block size is used, whereas ccrypt uses a 256-bit block size. Ccrypt commonly uses the .cpt file extension for encrypted.

In order to encrypt file using this tool, use following syntax:
ccrypt filename
To encrypt a file : impfile
ccrypt impfile
It will prompt for password couple of times, and once done, it will remove your source file and save the file with .cpt extension.
Source file have been removed and only encrypted file is there:
Now in order to decrypt an already encrypted file, command syntax is:
ccrypt –d encryptedfilename
So, Decrypt the encrypted file as:
ccrypt –d impfile.cpt
It will ask for password and will decrypt the file.
