Screenshot of AS-File Crypt 6.0
Encryption program for files that uses Salsa20, ChaCha20 or HC-256 with a 256-bit key. The program creates an encrypted (password protected) copy of any file and the program can later be used to decrypt (restore) the original file.
Benefits
- The program can integrate with Windows which means that you can right-click on a file and choose "AS-File Crypt" in the menu. (The integration feature is activated from the File menu. This is a non-portable feature.)
- This encryption program makes use of a key strengthening algorithm which delays the final encryption key, this increases the security.
- The encrypted file contains an encrypted checksum of the original file, which is verified at decryption.
- You don't need to enter the password twice, instead you can press [F12] if you want to show or hide the password.
- The speed is measured every time you encrypt or decrypt a file and the program displays the result when it's done.

Information regarding the integration feature
You have to run AS-File Crypt as Administrator in order to add/update or remove the integration feature. This can be done by right-clicking on the EXE file. (Note: When you make a larger Windows upgrade, this integration may be cleared, then you need to add it again.)
Portable?
The only thing that is not portable is the integration feature, but this has to be activated manually. The integration feature writes to the registry (the key "HKEY_CLASSES_ROOT").
