Joomla-cms: [4.0] php 7.4 Hitting a wall with password hash algorithm Argon2

[ghazal]

PHP 7.4
web servers : bitnami and xampp

I have been trying to test joomla 4 with php 7.4.
BDD is installed OK but I can't overcome this error while entering a password:

"This is not implemented, as it is not possible to implement Argon2i with acceptable performance in pure-PHP "
Tested on bitnami and xampp vm for mac, both equipped with php 7.4.

Any workaround ?
I know it's quite early to ask that but as I noticed some of you were already testing php 7.4, I wondered if someone had a solution.

You need to install ext/sodium through PECL or compile PHP with Argon support enabled (both of which require libsodium installed).

The sodium_compat library cannot polyfill all functions in pure PHP, you have hit one of those cases.

Issue can be closed, nothing to do with core Joomla.

Closing as not a core issue, see https://github.com/joomla/joomla-cms/issues/27375#issuecomment-569517885 for details.

Thanks anyway.

@ghazal No problem. Thanks for reporting. Better a false alarm for no bug than no alarm for a bug.

And thanks @mbabker for the information above.
