使用方法：
加密
点击复制代码 PHP
 $txt="78moban";
 $pubkey="公钥"
 $macdata = RSAEncrypt::encrypt($txt, $pubkey);
解密
点击复制代码 PHP
 $txt="78moban";
 $pubkey="私钥"
 $macdata = RSAEncrypt::decrypt($txt, $pubkey);
类文件
点击复制代码 PHP
class RSAEncrypt {
    public static function encrypt($str, $publicKey) {
        $pubKey = openssl_pkey_get_public($publicKey);
        openssl_public_encrypt($str, $outStr, $pubKey);
        return base64_encode($outStr);
    }
    
    public static function decrypt($str, $privateKey) {
        $inputByte = base64_decode($str);
        $decoded = base64_decode($privateKey);
        $priKey = openssl_pkey_get_private($decoded);
        openssl_private_decrypt($inputByte, $outStr, $priKey);
        return $outStr;
    }
}
