ChaCha20 Poly1305 IETF decrypt fails with Invalid MAC (works on libsodium native) about sodium_compat HOT 5 CLOSED

That's interesting. I'm not having any luck reproducing a failure, so I've committed a test case. Hopefully, if there is a bug, Travis CI will find it. 74d0528

I am sorry. I forget to give more information. I am using the following PHP version:

php-5.6.30-Win32-VC11-x64

Just to make it simple, i uploaded a full package: https://www.dropbox.com/s/s6ccf69x8jjhkkv/php-5.6.30-Win32-VC11-x64.rar?dl=0

Steps i did:

1. Download: http://windows.php.net/downloads/releases/php-5.6.30-Win32-VC11-x64.zip
2. Make php.ini to load required OpenSSL extension
3. Fetch composer
4. Add sodium_compat via composer
5. Add test.php and run it.

Looks like there are some outstanding issues with 32-bit integers, which the rest of the world no longer uses (PHP 7+ on Windows or PHP >= 5.6 on Linux). This is going to be a fun fix.

I've opened #38 to deal with the bigger issue.

In the meantime, if you upgrade to 7.0, then you'll be able to solve this problem immediately.

Thanks for verifying! Unfortunately i need to stick to PHP 5.6 at the moment. (Though I am eagerly following the current ext/sodium merge/licensing discussion for PHP 7.2...)

If think we can close this bug in favor of #38 .

Thanks again!
