Description
Pick Encrypt or Decrypt, type the path and your password. Folders too, in a console window, with every step on screen. Works offline.
For anyone who wants to protect a file or a folder before sending it or storing it, with a menu for quick use and command-line options for scripts.
It encrypts any single file or whole folder and decrypts it again with the same password. It runs in a console window, not a graphical one. Keep your password safe. It uses the tar tool that comes with Windows 10 and 11.
Features
- Encrypts and decrypts single files and whole folders.
- Compresses your data with Zstandard before it encrypts it, so the result is often smaller.
- Turns your password into keys with Argon2id (libsodium), four rounds deep.
- Uses all your CPU cores for the heavy steps.
- Splits very large files into parts when they do not fit in free RAM, and joins them again when you decrypt.
- Shows every step with timings, so you can see what it is doing.
- Simple menu: run it, pick Encrypt or Decrypt, type the path and your password.
- Command line for scripts: c-lcrypt -e to encrypt and -d to decrypt, with -p and -P.
- 100% offline, and it does its work in RAM.
