CMSG_CTRL_VERIFY_SIGNATURE_EX_PARA (Windows CE 5.0)
This structure contains information used to verify a message signature. It contains the signer index and signer public key. The signer public key can be the signer's CERT_PUBLIC_KEY_INFO structure, certificate context, or chain context.
typedef struct _CMSG_CTRL_VERIFY_SIGNATURE_EX_PARA { DWORD cbSize; HCRYPTPROV hCryptProv; DWORD dwSignerIndex; DWORD dwSignerType; void* pvSigner;} CMSG_CTRL_VERIFY_SIGNATURE_EX_PARA, *PCMSG_CTRL_VERIFY_SIGNATURE_EX_PARA;
Members
- cbSize
Size of this structure in bytes. - hCryptProv
Handle to the cryptographic provider that is used to verify the signature. If NULL, the cryptographic provider specified in CryptMsgOpenToDecode is used. If the hCryptProv in CryptMsgOpenToDecode is also NULL, the default provider according to the signer's public key OID is used. - dwSignerIndex
Index of the signer in the message. - dwSignerType
Indication of the structure containing the signer information. The following table shows the predefined values and the structures indicated.Value Description CMSG_VERIFY_SIGNER_PUBKEY CERT_PUBLIC_KEY_INFO CMSG_VERIFY_SIGNER_CERT CCERT_CONTEXT CMSG_VERIFY_SIGNER_CHAIN CERT_CHAIN_CONTEXT CMSG_VERIFY_SIGNER_NULL NULL - pvSigner
Pointer to a CERT_PUBLIC_KEY_INFO structure, a certificate context, a chain context, or NULL depending on the value of dwSignerType.
Remarks
If dwSignerType is CMSG_VERIFY_SIGNER_NULL, the signature is expected to contain only the unencrypted hash octets.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: Wincrypt.h.
