-.Dt CMS_COMPRESS 3
-.Os
-.Sh NAME
-.Nm CMS_compress
-.Nd create a CMS CompressedData structure
-.Sh SYNOPSIS
-.In openssl/cms.h
-.Ft CMS_ContentInfo *
-.Fo CMS_compress
-.Fa "BIO *in"
-.Fa "int comp_nid"
-.Fa "unsigned int flags"
-.Fc
-.Sh DESCRIPTION
-.Fn CMS_compress
-creates and returns a CMS CompressedData structure.
-.Fa comp_nid
-is the compression algorithm to use or
-.Dv NID_undef
-to use the default algorithm (zlib compression).
-.Fa in
-is the content to be compressed.
-.Fa flags
-is an optional set of flags.
-.Sh NOTES
-The only currently supported compression algorithm is zlib using the NID
-.Dv NID_zlib_compression .
-.Pp
-If zlib support is not compiled into OpenSSL then
-.Fn CMS_compress
-will return an error.
-.Pp
-If the
-.Dv CMS_TEXT
-flag is set, MIME headers for type
-.Sy text/plain
-are prepended to the data.
-.Pp
-Normally the supplied content is translated into MIME canonical format
-(as required by the S/MIME specifications); if
-.Dv CMS_BINARY
-is set, no translation occurs.
-This option should be used if the supplied data is in binary format;
-otherwise the translation will corrupt it.
-If
-.Dv CMS_BINARY
-is set then
-.Dv CMS_TEXT
-is ignored.
-.Pp
-If the
-.Dv CMS_STREAM
-flag is set a partial
-.Vt CMS_ContentInfo
-structure is returned suitable for streaming I/O: no data is read from
-the
-.Vt BIO
-.Fa in .
-.Pp
-The compressed data is included in the
-.Vt CMS_ContentInfo
-structure, unless
-.Dv CMS_DETACHED
-is set, in which case it is omitted.
-This is rarely used in practice and is not supported by
-.Xr SMIME_write_CMS 3 .
-.Sh NOTES
-If the flag
-.Dv CMS_STREAM
-is set, the returned
-.Vt CMS_ContentInfo
-structure is
-.Em not
-complete and outputting its contents via a function that does not
-properly finalize the
-.Vt CMS_ContentInfo
-structure will give unpredictable results.
-.Pp
-Several functions including
-.Xr SMIME_write_CMS 3 ,
-.Xr i2d_CMS_bio_stream 3 ,
-.Xr PEM_write_bio_CMS_stream 3
-finalize the structure.
-Alternatively finalization can be performed by obtaining the streaming
-ASN1
-.Vt BIO
-directly using
-.Xr BIO_new_CMS 3 .
-.Pp
-Additional compression parameters such as the zlib compression level
-cannot currently be set.
-.Sh RETURN VALUES
-.Fn CMS_compress
-returns either a
-.Vt CMS_ContentInfo
-structure or
-.Dv NULL
-if an error occurred.
-The error can be obtained from
-.Xr ERR_get_error 3 .
-.Sh SEE ALSO
-.Xr CMS_uncompress 3 ,
-.Xr ERR_get_error 3
-.Sh HISTORY
-.Fn CMS_compress
-was added to OpenSSL 0.9.8.
-The
-.Dv CMS_STREAM
-flag was first supported in OpenSSL 1.0.0.
