Plug.Crypto.KeyGenerator (Plug.Crypto v1.2.2) View Source
KeyGenerator implements PBKDF2 (Password-Based Key Derivation Function 2),
part of PKCS #5 v2.0 (Password-Based Cryptography Specification).
It can be used to derive a number of keys for various purposes from a given secret. This lets applications have a single secure secret, but avoid reusing that key in multiple incompatible contexts.

Returns a derived key suitable for use.
:iterations- defaults to 1000 (increase to at least 2^16 if used for passwords);
:length- a length in octets for the derived key. Defaults to 32;
:digest- an hmac function to use as the pseudo-random function. Defaults to
:cache- an ETS table name to be used as cache. Only use an ETS table as cache if the secret and salt is a bound set of values. For example:
:ets.new(:your_name, [:named_table, :public, read_concurrency: true])
