# CMS\_sign\_receipt(3ssl)

create a CMS signed receipt

## NAME

CMS\_sign\_receipt - create a CMS signed receipt

## SYNOPSIS

```
 #include <openssl/cms.h>
 CMS_ContentInfo *CMS_sign_receipt(CMS_SignerInfo *si, X509 *signcert,
                                   EVP_PKEY *pkey, STACK_OF(X509) *certs,
                                   unsigned int flags);
```

## DESCRIPTION

**CMS\_sign\_receipt()** creates and returns a CMS signed receipt structure. **si** is the **CMS\_SignerInfo** structure containing the signed receipt request. **signcert** is the certificate to sign with, **pkey** is the corresponding private key.  **certs** is an optional additional set of certificates to include in the CMS structure (for example any intermediate CAs in the chain).

**flags** is an optional set of flags.

## NOTES

This functions behaves in a similar way to **CMS\_sign()** except the flag values **CMS\_DETACHED**, **CMS\_BINARY**, **CMS\_NOATTR**, **CMS\_TEXT** and **CMS\_STREAM** are not supported since they do not make sense in the context of signed receipts.

## RETURN VALUES

**CMS\_sign\_receipt()** returns either a valid CMS\_ContentInfo structure or NULL if an error occurred.  The error can be obtained from **ERR\_get\_error**(3).

## SEE ALSO

**ERR\_get\_error**(3), **CMS\_verify\_receipt**(3), **CMS\_sign**(3)
