Description:
------------
I downloaded PHP 7.2.0alpha2 for Windows / VC15 x64 Non Thread Safe (2017-Jun-21 00:03:34) and I'm not seeing libsodium in it. According to https://wiki.php.net/rfc/libsodium it's supposed to be in PHP 7.2.

I don't see any "sodium" or "libsodium" extension in the ext directory.

The word "sodium" does not appear in the output of php -i:

https://pastebin.com/N8wtGG8c

I also tried the example at the end of https://paragonie.com/book/pecl-libsodium/read/05-publickey-crypto.md#crypto-sign-seed-keypair and it didn't work.



Test script:
---------------
<?php

$bob_seed = \Sodium\randombytes_buf(\Sodium\CRYPTO_SIGN_SEEDBYTES);
$bob_sign_kp = \Sodium\crypto_sign_seed_keypair($bob_seed);

Expected result:
----------------
Not a Fatal error...

Actual result:
--------------
Fatal error: Uncaught Error: Call to undefined function Sodium\randombytes_buf() in C:\path\to\test.php:3
Stack trace:
#0 {main}
  thrown in C:\path\to\test.php on line 3

PR is being worked on https://github.com/php/php-src/pull/2560 and feature freeze isn't until July 20th.

I'll leave this open as a reminder but right now there is no problem.


Note that it will use global functions and constants, not a namespace.

$bob_seed = sodium_randombytes_buf(SODIUM_CRYPTO_SIGN_SEEDBYTES);
$bob_sign_kp = sodium_crypto_sign_seed_keypair($bob_seed);
