Argon2IPasswordEncoder uses native `password_hash()` and `password_verify()` functions if the current PHP installation embeds Argon2 support (>=7.2, compiled `--with-password-argon2`).
Otherwise, it fallbacks to the libsodium extension.
This was fine at time the encoder was introduced, but meanwhile libsodium changed the algorithm used by `sodium_crypto_pwhash_str()` which is now argon2id, that goes outside of the scope of the encoder which was designed to deal with `argon2i` only.
Nothing we can do as databases may already contain passwords hashed with argon2id, the encoder must keep validating those.
However, the PHP installation may change as time goes by, and could suddenly embed the Argon2 core integration. In this case, the encoder would use the `password_verify()` function which would fail in case the password was not hashed using argon2i.
This PR prevents it by detecting that argon2id was used, avoiding usage of `password_verify()`.
See https://github.com/jedisct1/libsodium-php/issues/194 and https://github.com/symfony/symfony/issues/28093 for references.
Patch cannot be tested as it is platform dependent.
Side note: I'm currently working on a new implementation for 4.3 that will properly supports argon2id (which has been added to the PHP core sodium integration in 7.3) and argon2i, distinctively.
