The ccrypt command in Linux is used to encrypt and decrypt files. It is a command-line tool that uses the Rijndael cipher, which is a secure and efficient encryption algorithm.
The ccrypt command is used in the following syntax:
The options can be used to specify the following:
-e : Encrypt the file.
-d : Decrypt the file.
-k : Specify the encryption key.
-p : Prompt for the encryption key.
-v : Verbose mode.
For example, to encrypt the file my_file.txt and save the encrypted file as my_file.enc, you would run the following command:
This command will encrypt the file my_file.txt and save the encrypted file as my_file.enc.
To decrypt the file my_file.enc and save the decrypted file as my_file.txt, you would run the following command:
This command will decrypt the file my_file.enc and save the decrypted file as my_file.txt.
To specify the encryption key, you would run the following command:
This command will encrypt the file my_file.txt using the encryption key my_key and save the encrypted file as my_file.enc.
To prompt for the encryption key, you would run the following command:
This command will encrypt the file my_file.txt and prompt you for the encryption key. The encryption key will be displayed on the screen only once, so be sure to write it down.
