Which OpenSSL version supports SHA256?

I have written a PHP library that uses the openssl_verify() and openssl_sign(), using SHA256. I think the SHA256 support is kind of new for PHP and OpenSSL, but I don't know which version started to support SHA256.

This causes some problems with the clients using earlier versions of OpenSSL and PHP and I couldn't find the version I specified above.

Which OpenSSL version first supported SHA256 in RSA signing and verifying?

Solution

  • Due to PHP DOCS OPENSSL_ALGO_SHA256 constant vas first added in PHP 5.4.8.

    I've also faced this problem while trying to verify SHA256. Don't know what to do now )
