SignerTimeStampEx function

The SignerTimeStampEx function time stamps the specified subject and optionally returns a pointer to a SIGNER_CONTEXT structure that contains a pointer to a BLOB. This function supports Authenticode time stamping. To perform X.509 Public Key Infrastructure (RFC 3161) time stamping, use the SignerTimeStampEx2 function.

Note  This function has no associated header file or import library. To call this function, you must create a user-defined header file and use the LoadLibrary and GetProcAddress functions to dynamically link to Mssign32.dll.
