在调用openssl_pkcs7_sign时,可以将算法作为一个设置项传入。 例如,使用以下代码指定SHA-1算法: $flags = PKCS7_DETACHED | PKCS7_BINARY | PKCS7_SIGN; $headers = array(); $sha1_oid = "1.3.14.3.2.26"; $result = openssl_pkcs7_sign( "message.txt", "signed_message.p7s", "cert.pem", "p...
可以通过openssl_pkcs7_sign函数返回的签名数据来验证使用的签名算法。签名数据包括签名使用的算法以及其他详细信息。您可以使用openssl_pkcs7_get_signers函数来获取签名者的详细信息,例如:$signers = openssl_pkcs7_get_signers($signature); foreach ($signers as $signer) { $algorithm = openssl_get_md_method_...

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...
