 Data is signed using ed25519, encrypted using xchacha20-poly1305 ietf and hashed using Blake2b.
 See src/Encryption.cpp, src/Signature.cpp and src/Hash.cpp.
 Also check Scheme.md for packet construction.
+## Password
+Data is stored encrypted on disk by using the hash of the user password. The password is hashed using Argon2i.
 # Limits
 Only 800kb of data can be used for each `add`. You can add more data by using `add` several times.
