in #31019.
In Symfony 3.4 we added an Argon2i password hasher as a modern replacement of the Bcrypt hasher. Argon2i support is provided through the libsodium library, which selects the Argon2 variant (argon2d, argon2i or argon2id) automatically based on the host system.
Given that the Argon2 variant selection is out of Symfony's control, in Symfony
4.3 we've decided to not add an Argon2idPasswordEncoder
, to deprecate the
Argon2iPasswordEncoder
class and to add instead a generic
SodiumPasswordEncoder
class.
This new encoder relies on libsodium to select the best possible Argon2 variant. In practice, the only change you'll need to make in most of your applications is to update the name of the hashing algorithm in the main security config file:
1 2 3 4 5 6 7 | # config/packages/security.yaml
security:
# ...
encoders:
App\Entity\User:
- algorithm: argon2i
+ algorithm: sodium
|
All the existing Argon2i configuration options are still available under the
new sodium
algorithm name.
