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.
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)
In your environment file, choose one of Pbkdf2
, Bcrypt
, Argon2
.
The default is 'Pbkdf2, but you still need to include it in your
mix.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
Also, be sure to look at comeonin config
Available in Hex, the package can be installed as:
Add comeonin_ecto_password to your list of dependencies in mix.exs
:
def deps do
[{:comeonin_ecto_password, "~> 3.0.0"}]
end
