CMS_final(3) OpenSSL CMS_final(3)NAME
CMS_final - finalise a CMS_ContentInfo structure
int CMS_final(CMS_ContentInfo *cms, BIO *data, BIO *dcont, unsigned int flags);
CMS_final() finalises the structure cms. It's purpose is to perform any operations necessary on cms (digest computation for example) and
set the appropriate fields. The parameter data contains the content to be processed. The dcont parameter contains a BIO to write content to
after processing: this is only used with detached data and will usually be set to NULL.
This function will normally be called when the CMS_PARTIAL flag is used. It should only be used when streaming is not performed because the
streaming I/O functions perform finalisation operations internally.
CMS_final() returns 1 for success or 0 for failure.

CMS_final() was added to OpenSSL 0.9.8

CMS_uncompress - uncompress a CMS CompressedData structure
int CMS_uncompress(CMS_ContentInfo *cms, BIO *dcont, BIO *out, unsigned int flags);
CMS_uncompress() extracts and uncompresses the content from a CMS CompressedData structure cms. data is a BIO to write the content to and
flags is an optional set of flags.
The dcont parameter is used in the rare case where the compressed content is detached. It will normally be set to NULL.
The only currently supported compression algorithm is zlib: if the structure indicates the use of any other algorithm an error is returned.
If zlib support is not compiled into OpenSSL then CMS_uncompress() will always return an error.
The following flags can be passed in the flags parameter.
If the CMS_TEXT flag is set MIME headers for type text/plain are deleted from the content. If the content is not of type text/plain then an
error is returned.
CMS_uncompress() returns either 1 for success or 0 for failure. The error can be obtained from ERR_get_error(3)BUGS
The lack of single pass processing and the need to hold all data in memory as mentioned in CMS_verify() also applies to CMS_decompress().
