This is not implemented, as it is not possible to implement Argon2i with acceptable performance in pure-PHP

Question

I am using xampp and it's php version is 7.3.27. I am trying to install magento version-2.4.2 in ubuntu linux. But i am facing this problem. I have found several solution to install libosodium extension on internet to solve this problem. But it is not clear, how to install it in xampp php folder, not in the usr/bin/php folder. Because i am using xampp php as default php.

Answer 1

This error occurs with Magento 2.4.2 when php does not include the sodium php extension.

You can check if this extension is installed with

php -i | grep sodium
sodium support => enabled
libsodium headers version => 1.0.16

To fix this problem install / activate the sodium php extension.

For Xampp in php.ini add (or uncomment)

extension=sodium;

Or

sudo apt install php-libsodium

NOTE the supported PHP version for Magento 2.4 is PHP 7.4

Answer 2

While installing Magento 2.4.2 this error occurs which indicates your PHP and Apache do not have "Sodium" extension ON.

For WAMP or WAMP64 users, you will need to remove ";" infront of extension=sodium line written in wamp64\bin\apache\apache2.4.41\bin\php.ini and

wamp64\bin\php\phpX.X.x\php.ini

then it would be worked.

There is default PHP installed as a system package but if you are using self contained installation of PHP (XAMPP [Binami]) then you have to provide php-config path in following attribute of ./configure command while installing the LIBSODIUM for your PHP.

--with-php-config

I have installed xampp-linux-x64-7.4.15-0 and surprisingly there is no sodium PHP module in this setup. I installed Sodium library first and then install PHP Libsodium extesnion for XAMPP.

/opt/lampp/etc/php -m    //Check if you have sodium installed 

sudo apt-get update
sudo apt-get install build-essential libtool autoconf 

Download stable version of Sodium Library by following link

https://download.libsodium.org/libsodium/releases/ libsodium-1.x.x-stable.tar.gz

//Go inside the package folder

cd <downloaded package dir>

./configure 

make

sudo make install

It will install library and you can check inside the /usr/local/lib/. The file for libsodium has been created with so extension.

Now we will download and install PHP library for

https://github.com/jedisct1/libsodium-php

//Go inside the package folder

cd <downloaded package dir>

phpize   // This will create configure script.

./configure --with-php-config=/opt/lampp/bin/php-config   //This time we provided preferred php config

make

sudo make install

This will isntall extension for XAMPP PHP and you can check sodium.so file has been created inside /opt/lampp7.4/lib/php/extensions/no-debug-non-zts-2019****.

Add extension inside php.ini

sudo bash -c 'echo "extension="sodium.so"" >> /opt/lampp/etc/php.ini'

Restart XAMPP and check installed php modules

sudo /opt/lampp/lampp restart

/opt/lampp/etc/php -m 

If all works fine then you will find sodium in list defiantly.

Answer 4

There are 4 solutions to resolve this error on WINDOWS XAMPP.

Solution 1:-

One of the reason for this error is sodium extension not enabled in php.ini file, so we need to enable it and re-run install command in the command prompt.

To enable:-

Go to C:\xampp\php\php.ini, find "extension=sodium" in it and then remove semicolon from beginning of this line to enable PHP extensions sodium. Save the file.

Then restart Apache means stop and start Apache from the Xampp Control Panel.

That’s it.
