SYNOPSIS

 #include <openssl/cms.h>

 CMS_ReceiptRequest *CMS_ReceiptRequest_create0(unsigned char *id, int idlen, int allorfirst, STACK_OF(GENERAL_NAMES) *receiptList, STACK_OF(GENERAL_NAMES) *receiptsTo);
 int CMS_add1_ReceiptRequest(CMS_SignerInfo *si, CMS_ReceiptRequest *rr);
 int CMS_get1_ReceiptRequest(CMS_SignerInfo *si, CMS_ReceiptRequest **prr);
 void CMS_ReceiptRequest_get0_values(CMS_ReceiptRequest *rr, ASN1_STRING **pcid, int *pallorfirst, STACK_OF(GENERAL_NAMES) **plist, STACK_OF(GENERAL_NAMES) **prto);

DESCRIPTION

CMS_ReceiptRequest_create0() creates a signed receipt request structure. The signedContentIdentifier field is set using id and idlen, or it is set to 32 bytes of pseudo random data if id is If receiptList is the allOrFirstTier option in receiptsFrom is used and set to the value of the allorfirst parameter. If receiptList is not the receiptList option in receiptsFrom is used. The receiptsTo parameter specifies the receiptsTo field value.

The CMS_add1_ReceiptRequest() function adds a signed receipt request rr to SignerInfo structure si.

int CMS_get1_ReceiptRequest() looks for a signed receipt request in si, if any is found it is decoded and written to prr.

CMS_ReceiptRequest_get0_values() retrieves the values of a receipt request. The signedContentIdentifier is copied to pcid. If the allOrFirstTier option of receiptsFrom is used its value is copied to pallorfirst otherwise the receiptList field is copied to plist. The receiptsTo parameter is copied to prto.

NOTES

For more details of the meaning of the fields see

The contents of a signed receipt should only be considered meaningful if the corresponding CMS_ContentInfo structure can be successfully verified using CMS_verify().
