session_keys 0.1.0

SessionKeys is a cryptographic tool for the deterministic generation of NaCl compatible [Curve25519](https://cr.yp.to/ecdh.html) encryption and [Ed25519](http://ed25519.cr.yp.to) digital signature keys. The strength of the system lies in the fact that the keypairs are derived from passing an identifier, such as a username or email address, and a high-entropy passphrase through the `SHA256` hash and the `scrypt` key derivation functions. This means that no private key material need ever be stored to disk. The generated keys are deterministic; for any given ID, password, and strength combination the same keys will always be returned. The generated ID is passed through `SHA256` and `scrypt` and is derived from only the ID parameter your provide and a common salt. The password is also passed through `SHA256` and `scrypt` and NaCl encryption and signing keypairs are derived from the combination of the stretched ID, your password, and a common salt.
