CMS_ReceiptRequest_create0, CMS_add1_ReceiptRequest, CMS_get1_ReceiptRequest, CMS_ReceiptRequest_get0_values -- CMS signed receipt request functions.
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 NULL. If
receiptList is NULL the
allOrFirstTier option in receiptsFrom is used and set to the value of
the allorfirst parameter. If
receiptList is not NULL 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 RFC2634.
The contents of a signed receipt should only be considered meaningful
if the corresponding CMS_ContentInfo structure can be successfully
verified using CMS_verify().
RETURN VALUES
CMS_ReceiptRequest_create0() returns a signed receipt request
structure or NULL if an error occurred.
CMS_add1_ReceiptRequest() returns 1 for success or 0 is an error
occurred.
CMS_get1_ReceiptRequest() returns 1 is a signed receipt request is
found and decoded. It returns 0 if a signed receipt request is not
present and -1 if it is present but malformed.
