AS-File Crypt 5.0 - Encrypt files with Salsa20 or ChaCha20.
Screenshot of AS-File Crypt 5.0
Encryption program for files that uses Salsa20 or ChaCha20 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.
- 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.)
- The speed is measured during each encryption / decryption operation and the program will display the results for you when it's done.
- This encryption program makes use of a key strengthening algorithm which delays the final encryption key for a few seconds, this increases the security.
- You don't need to enter password and nonce twice, instead you can press [F12] if you want to show or hide password and nonce.
- The program stores an encrypted checksum of the original file, which is verified at decryption.

Information regarding the integration feature
If you have User Account Control (UAC) activated 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.
My implementations of Salsa20 and ChaCha20 used in this program are quite slow. If you are looking for higher-speed encryption (e.g., if you want to encrypt large files) I would recommend my other program AS-AESCTR instead, this program can be found on the page Extras. The program AS-AESCTR is a command line program.
