Length of Hash
thiamsantos opened this issue · comments
What is the length of the hash generated by Pbkdf2? I need this to set the size of the database field.
It depends on the options you use, but for the default options, it is 131. You can check it in the Elixir shell (run iex -S mix):
Comeonin.Pbkdf2.hashpwsalt("") |> byte_size()
131
Comeonin.Pbkdf2.hashpwsalt("", digest: :sha256) |> byte_size()
88
Thanks!
