It is currently dependent on ccrypt. It is ccrypt that performs the encryption and not Pcrypt. Ccrypt is a cross-platform file encryption utility which means that encrypted files are portable across all supported operating systems and processors, including Linux, Windows, and Macintosh OS-X. Ccrypt uses the Rijndael cipher with 256-bit encryption which is currently considered to be unbreakable and the experts consider that it will be good for at least several decades.
For encryption: either access Pcrypt from the main menu [Menu > Personal > Pcrypt] or access ccrypt from the right-click context menu. Encrypted files will be saved with the extension .cpt. To encrypt directories first compress into a single file by entering tar cfzv filename.tgz subdirectory into a terminal.
For decryption: just left-click on the file. Any files with the .cpt extension will be assumed to have been encrypted with ccrypt, and so ccrypt will attempt to decrypt them. Any other input files will be encrypted, but via right-clicking, or the menu, only.
For secure deletion: first encrypt, then delete, then forget.
Passphrases can consist of any number of characters, but it should be at least 8 characters long if you value your privacy. Ccrypt internally hashes the key to 256 bits regardless of the passphrase size. All characters supplied are significant since the stronger your passphrase the more secure your data will be.
WARNING: If you forget or lose the encryption key (passphrase) your file may never be opened again.
Pcrypt requires that ccrypt be also installed:
ccrypt-1.9 software package; sha1sum 539aa3709726b38312f2aef98588fc028a5e19e6
For Puppy 4.1.1 to 4.3.0:
pcrypt-20091005 software package
For Puppy 4.3.1+:
pcrypt-20091008 software package
When installed available from: Menu > Personal > Pcrypt
