使用openssl_pkcs7_sign函数签署数据时,将第三个参数设置为OPENSSL_ALGO_SHA1。 注意:在使用SHA1算法之前,请确保您的PHP版本支持SHA1算法,并且已正确安装OpenSSL扩展。 2. 如何在PHP中使用openssl_pkcs7_sign函数进行数字签名时选择SHA1算法? 要在openssl_pkcs7_sign函数中选择SHA1算法进行数字签名,请按照以下步骤...
可以通过openssl_pkcs7_sign函数返回的签名数据来验证使用的签名算法。签名数据包括签名使用的算法以及其他详细信息。您可以使用openssl_pkcs7_get_signers函数来获取签名者的详细信息,例如:$signers = openssl_pkcs7_get_signers($signature); foreach ($signers as $signer) { $algorithm = openssl_get_md_method_...

One of the problems I see (I am shure there are others) is that I am not freeing the result from PKCS7_sign. How do I release m.smsg in this case? I tried BIO_free on it but of course it does not work, there must be some function somewhere for releasing a PKCS7 structure. An...

It's probably worth noting that I had a great deal of difficulty getting either Mozilla 1.4 or Outlook Express 6 to verify signatures generated by openssl_pkcs7_sign() until I added a newline (\n) to the beginning of the message I was signing. Not sure why that is, but as soon as...
