Implementations

impl CredentialGuard

pub fn new(salt: DbSalt, username: &str, password: &str) -> CredentialGuard

Generate a new CredentialGuard from the database’s unique salt and the user’s name and password.

pub fn update_credentials(&mut self, username: &str, password: &str)

Update the user’s name and password

pub fn try_decrypt_key(self, encrypted_key: Vec<u8>) -> Result<DataGuard, Self>

Try to decrypt the key using the current user’s name and password. If successful, this CredentialGuard is consumed and a DataGuard is returned, which can be used to encrypt/decrypt data. Upon failure, this guard is returned and the guard’s credentials should be updated before calling this function again.

pub fn generate_encrypted_key(&self) -> Result<Vec<u8>, UnspecifiedError>

Generate a randome symmetric encryption key for securing data. The key is encrypted using the user’s name and password and, as such, can be public.
