SIGNER_INFO Struct Reference

Contains message signer information.

The SIGNER_INFO structure contains information associated with a single signer of a CMS message (supported) or a PKI message (deprecated).

For a CMS message, use the SIGNER_INFO structure with the C_AddSignerToList(), C_AddUniqueSignerToList(), C_FreeSignerInfo(), C_InsertSignerInList(), and C_FreeSignerEntry() functions.
For a PKI message, the SIGNER_INFO structure represents the sender field of a PKI_MSG_FIELDS structure. However, the use of the SIGNER_INFO structure is deprecated in Cert-C 2.0. Use the PKI_SENDER_INFO structure (and its related C_SetPKIMsgSender() and C_GetPKIMsgSender() functions) instead.

Data Fields

signerCertId	A `CERT_IDENTIFIER` structure that identifies the signer's certificate.
digestAlgorithmId	An `ALGORITHM_IDENTIFIER` structure that identifies the message-digest algorithm under which the message data and signedAttributes, if present, are digested. See `ALGORITHM_IDENTIFIER`.
signedAttributes	An `ATTRIBUTES_OBJ` object that contains a set of attributes that are signed by the signer. This is an optional field; it can be set to `NULL_PTR`.
signatureAlgorithmId	An `ALGORITHM_IDENTIFIER` structure that identifies the signature algorithm to use to encrypt the digest. See `ALGORITHM_IDENTIFIER`.
unsignedAttributes	An `ATTRIBUTES_OBJ` object that contains a set of attributes that are included in the message but not signed by the signer. This is an optional field; it can be set to `NULL_PTR`.
