FAQ

1. Why do I need this? You can use this to encrypt any file with very strong and fast encryption algorithms.
2. What is a salt https://en.wikipedia.org/wiki/Salt_(cryptography)
3. Where is the salt file? It was generated in the folder where the encryptor and decryptor file is located named salt_[your_salt_name].txt.
4. Can I still decrypt my encrypted files if I lose the salt? Don't lose the salt. You won't be able to decrypt your files without it.
