| =head1 NAME |
| |
| CMS_ReceiptRequest_create0, CMS_add1_ReceiptRequest, CMS_get1_ReceiptRequest, CMS_ReceiptRequest_get0_values - CMS signed receipt request functions. |
| |
| =head1 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); |
| |
| =head1 DESCRIPTION |
| |
| CMS_ReceiptRequest_create0() creates a signed receipt request structure. The |
| B<signedContentIdentifier> field is set using B<id> and B<idlen>, or it is set |
| to 32 bytes of pseudo random data if B<id> is NULL. If B<receiptList> is NULL |
| the allOrFirstTier option in B<receiptsFrom> is used and set to the value of |
| the B<allorfirst> parameter. If B<receiptList> is not NULL the B<receiptList> |
| option in B<receiptsFrom> is used. The B<receiptsTo> parameter specifies the |
| B<receiptsTo> field value. |
| |
| The CMS_add1_ReceiptRequest() function adds a signed receipt request B<rr> |
| to SignerInfo structure B<si>. |
| |
| int CMS_get1_ReceiptRequest() looks for a signed receipt request in B<si>, if |
| any is found it is decoded and written to B<prr>. |
| |
| CMS_ReceiptRequest_get0_values() retrieves the values of a receipt request. |
| The signedContentIdentifier is copied to B<pcid>. If the B<allOrFirstTier> |
| option of B<receiptsFrom> is used its value is copied to B<pallorfirst> |
| otherwise the B<receiptList> field is copied to B<plist>. The B<receiptsTo> |
| parameter is copied to B<prto>. |
| |
| =head1 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(). |
| |
| =head1 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. |
