Simple Privacy Tool is a simple tool to encrypt and decrypt files. It uses the symmetric algorithm XChaCha-Poly1305 and Argon2id for the key derivation function.

Since this tool uses a symmetric algorithm, the level of privacy hinges solely on the password's strength. So, make sure to choose your password carefully.
