github.com/dwin/goSecretBoxPassword (go): Package password is a probably paranoid utility library for securly hashing and encrypting passwords based on the Dropbox method. This implementation uses Blake2b, Scrypt and XSalsa20-Poly1305 (via NaCl SecretBox) to create secure password hashes that are also encrypted using a master passphrase. If the master passphrase is lost you will lose access to all passwords encrypted with it so store is securely, my recommendation is that you store it as an environmental variable or in a config file to avoid storing it in source code.
