Comeonin Ecto Password

A custom Ecto type for storing encrypted passwords using Comeonin

For ecto 1 compatibility use the ecto-1 branch.

Version 3.x is compatible with comeonin ~> 5.0, use version 2.x for compatibility with older versions.

Usage

On your schema, define secure fields with this type:

field :password, Comeonin.Ecto.Password

Then on your changeset simply cast from plain-text params

changeset
|> cast(attrs, [:password])
|> validate_required([:password])

After casting the password will already be encrypted in the changeset, and can be saved to your table's string column.

To check for validity, do something like:

user = Repo.get_by(User, email: "[email protected]")
Comeonin.Ecto.Password.valid?("plain_password", user.password)

Configuration

In your environment file, choose one of Pbkdf2, Bcrypt, Argon2. The default is 'Pbkdf2, but you still need to include it in yourmix.exs`!

config :comeonin, Ecto.Password, Pbkdf2

# when using pkbdf2
config :comeonin, :pbkdf2_rounds, 120_000
config :comeonin, :pbkdf2_salt_len, 512

# when using bcrypt
config :comeonin, :bcrypt_log_rounds, 14
