OneSM3 PHP Library: Installation, Usage, and Performance Comparison with OpenSSL

OneSM3 is a PHP library implementing the SM3 cryptographic hash algorithm, with source code hosted on GitHub.

Code repository : https://github.com/lizhichao/sm

Installation : Use Composer to add the package.

composer require lizhichao/one-sm

Usage examples:

require __DIR__ . '/vendor/autoload.php';

// String signature

echo \OneSm\Sm3::sign('abc') . PHP_EOL;

echo \OneSm\Sm3::sign(str_repeat("adfas哈哈哈", 100)) . PHP_EOL;

// File signature

echo \OneSm\Sm3::signFile(__FILE__) . PHP_EOL;

Performance testing compares the library against OpenSSL and another PHP SM3 implementation (SM3-PHP). Run the benchmark script:

php bench.php

The benchmark results show identical hash values for OpenSSL and one-sm3, while SM3-PHP produces a different hash; execution times are approximately 4.76 ms for OpenSSL, 5.53 ms for one-sm3, and 708 ms for SM3-PHP.
