Data is encrypted with XChaCha20Poly1305

The encryption key is derived from the password hash we generate using the Argon2id hashing alogrithm.

Both salt needed for the Argon2id hash and the nonce for the encryption key are derived from the sha256 hash of the username input.

To make sure to be able to decrypt the file using the same credentials the Argon2id parameters are saved at the end of the file as plaintext.

For example if we take a txt file:

Some Text

It will look like this:

&³�1�:ß�¥�\˺Ás%;8#4à5
xqparams  �    È   �       @
