Detailed Description

This structure contains information about a SignedData object's signer. The structure (when populated) provides signing information to the PKCS7_SignData() function.

Field Documentation

digestAlgoOID

const ubyte* signerInfoPtr::digestAlgoOID

Stores a pointer to the OID for the message digest method to use for this signer. Valid values for this member are pointers to md5_OID or sha1_OID, which are defined in src/asn1/oiddefs.h.

pAuthAttrs

Attribute* signerInfoPtr::pAuthAttrs

NULL or a pointer to an Attributes structure for the signer's authenticated attributes. If there is more than one attribute, use this member to reference an array of Attributes structures.

These attributes are optional if the ContentInfo object's type is data.

pUnauthAttrs

Attribute* signerInfoPtr::pUnauthAttrs

NULL or a pointer to an Attributes structure for the signer's non-authenticated attributes. If there is more than one attribute, use this member to reference an array of Attributes structures.

The atttribute types are as defined by PKCS #9.
