+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+The function \fBCMS_get0_SignerInfos()\fR returns all the CMS_SignerInfo structures
+associated with a \s-1CMS\s0 signedData structure.
+.PP
+\&\fBCMS_SignerInfo_get0_signer_id()\fR retrieves the certificate signer identifier
+associated with a specific CMS_SignerInfo structure \fBsi\fR. Either the
+keyidentifier will be set in \fBkeyid\fR or \fBboth\fR issuer name and serial number
+in \fBissuer\fR and \fBsno\fR.
+.PP
+\&\fBCMS_SignerInfo_get0_signature()\fR retrieves the signature associated with
+\&\fBsi\fR in a pointer to an \s-1ASN1_OCTET_STRING\s0 structure. This pointer returned
+corresponds to the internal signature value if \fBsi\fR so it may be read or
+modified.
+.PP
+\&\fBCMS_SignerInfo_cert_cmp()\fR compares the certificate \fBcert\fR against the signer
+identifier \fBsi\fR. It returns zero if the comparison is successful and non zero
+if not.
+.PP
+\&\fBCMS_SignerInfo_set1_signer_cert()\fR sets the signers certificate of \fBsi\fR to
+\&\fBsigner\fR.
+.SH "NOTES"
+.IX Header "NOTES"
+The main purpose of these functions is to enable an application to lookup
+signers certificates using any appropriate technique when the simpler method
+of \fBCMS_verify()\fR is not appropriate.
+.PP
+In typical usage and application will retrieve all CMS_SignerInfo structures
+using \fBCMS_get0_SignerInfo()\fR and retrieve the identifier information using
+\&\s-1CMS.\s0 It will then obtain the signer certificate by some unspecified means
+(or return and error if it cannot be found) and set it using
+\&\fBCMS_SignerInfo_set1_signer_cert()\fR.
+.PP
+Once all signer certificates have been set \fBCMS_verify()\fR can be used.
+.PP
+Although \fBCMS_get0_SignerInfos()\fR can return \s-1NULL\s0 if an error occurs \fBor\fR if
+there are no signers this is not a problem in practice because the only
+error which can occur is if the \fBcms\fR structure is not of type signedData
+due to application error.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBCMS_get0_SignerInfos()\fR returns all CMS_SignerInfo structures, or \s-1NULL\s0 there
+are no signers or an error occurs.
+.PP
+\&\fBCMS_SignerInfo_get0_signer_id()\fR returns 1 for success and 0 for failure.
+.PP
+\&\fBCMS_SignerInfo_cert_cmp()\fR returns 0 for a successful comparison and non
+zero otherwise.
+.PP
+\&\fBCMS_SignerInfo_set1_signer_cert()\fR does not return a value.
+.PP
+Any error can be obtained from \fBERR_get_error\fR\|(3)
