WinHyptoAPI没有validationphp openssl签名的string

我正在使用php openssl签署一些文本,并尝试使用CryptoApi在Windows应用程序中进行validation,但validation总是失败。 请帮我一下

PHP代码:

<?php $data = "data that is to be hashed and signed."; $private_key = <<<EOD -----BEGIN RSA PRIVATE KEY----- MIIBOgIBAAJBANDiE2+Xi/WnO+s120NiiJhNyIButVu6zxqlVzz0wy2j4kQVUC4Z RZD80IY+4wIiX2YxKBZKGnd2TtPkcJ/ljkUCAwEAAQJAL151ZeMKHEU2c1qdRKS9 sTxCcc2pVwoAGVzRccNX16tfmCf8FjxuM3WmLdsPxYoHrwb1LFNxiNk1MXrxjH3R 6QIhAPB7edmcjH4bhMaJBztcbNE1VRCEi/bisAwiPPMq9/2nAiEA3lyc5+f6DEIJ h1y6BWkdVULDSM+jpi1XiV/DevxuijMCIQCAEPGqHsF+4v7Jj+3HAgh9PU6otj2n Y79nJtCYmvhoHwIgNDePaS4inApN7omp7WdXyhPZhBmulnGDYvEoGJN66d0CIHra I2SvDkQ5CmrzkW5qPaE2oO7BSqAhRZxiYpZFb5CI -----END RSA PRIVATE KEY----- EOD; $public_key = <<<EOD -----BEGIN PUBLIC KEY----- MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBANDiE2+Xi/WnO+s120NiiJhNyIButVu6 zxqlVzz0wy2j4kQVUC4ZRZD80IY+4wIiX2YxKBZKGnd2TtPkcJ/ljkUCAwEAAQ== -----END PUBLIC KEY----- EOD; $binary_signature = ""; // At least with PHP 5.2.2 / OpenSSL 0.9.8b (Fedora 7) // there seems to be no need to call openssl_get_privatekey or similar. // Just pass the key as defined above openssl_sign($data, $binary_signature, $private_key, OPENSSL_ALGO_SHA1); // Check signature $ok = openssl_verify($data, $binary_signature, $public_key, OPENSSL_ALGO_SHA1); echo $binary_signature; echo "\n"; echo strlen($binary_signature); echo "\n"; echo strlen($public_key); $binary_signature="ÅâŸoÀÞü¸IOT6ê¿›¹ý “´Šæ¸Û à$,&† -X÷bË`‡0¥u«CAÚNgϼ‡Êû`Sî"; echo "check #1: "; echo sha1($data); if ($ok == 1) { echo "signature ok (as it should be)\n"; } elseif ($ok == 0) { echo "bad (there's something wrong)\n"; } else { echo "ugly, error checking signature\n"; } $ok = openssl_verify('tampered'.$data, $binary_signature, $public_key, OPENSSL_ALGO_SHA1); echo "check #2: "; if ($ok == 1) { echo "ERROR: Data has been tampered, but signature is still valid!

要验证使用CryptoAPI,反转签名,然后验证。 这是因为,在Windows上,字节顺序不同于OpenSSL(即大端)。

你可以通过以下方式来完成

 for(i=0, j=dwSigLen-1; i<j; ++i, --j) { char t = pbSignature[i]; pbSignature[i] = pbSignature[j]; pbSignature[j] = t; } 

之后,验证签名。

这个问题可以帮助你,因为它面临类似的问题(从CryptoAPI签名,并使用OpenSSL验证)。
