NAME

        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.
