PROPID_M_PROV_NAME

The PROPID_M_PROV_NAME property specifies the name of the cryptographic provider used to generate the message's digital signature.

Type Indicator

VT_LPWSTR

PROPVARIANT Field

pwszVal

Property Values

Unicode string of the provider name (the default is "Microsoft Base Cryptographic Provider, Ver. 1.0").

Remarks

The PROPID_M_PROV_NAME property is typically used when working with foreign queues. The name and type (PROPID_M_PROV_TYPE) of the cryptographic provider is required to validate the digital signature of messages sent to a foreign queue or messages passed to MSMQ from a foreign queue. For information on sending authenticated messages to a foreign queue, see MSMQ Connector Server.

When PROPID_M_PROV_NAME is passed to MQSendMessage, MSMQ automatically sets PROPID_M_PROV_NAME_LEN to the length of the provider name.

To find out the name of the cryptographic provider used, pass PROPID_M_PROV_NAME and PROPID_M_PROV_NAME_LEN to MQReceiveMessage and examine the returned values.
