Plug.Crypto.KeyGenerator
KeyGenerator is a simple implementation of PBFDF2.
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.
Summary
| generate(secret, salt, opts \\ []) | Returns a derived key suitable for use |
Functions
Returns a derived key suitable for use.
Options
: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:sha256;: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])
