| 53 | .Os | ||
| 54 | .Sh NAME | ||
| 55 | .Nm CMS_uncompress | ||
| 56 | .Nd uncompress a CMS CompressedData structure | ||
| 57 | .Sh SYNOPSIS | ||
| 58 | .In openssl/cms.h | ||
| 59 | .Ft int | ||
| 60 | .Fo CMS_uncompress | ||
| 61 | .Fa "CMS_ContentInfo *cms" | ||
| 62 | .Fa "BIO *dcont" | ||
| 63 | .Fa "BIO *out" | ||
| 64 | .Fa "unsigned int flags" | ||
| 65 | .Fc | ||
| 66 | .Sh DESCRIPTION | ||
| 67 | .Fn CMS_uncompress | ||
| 68 | extracts and uncompresses the content of a CMS | ||
| 69 | .Vt CompressedData | ||
| 70 | structure | ||
| 71 | .Fa cms | ||
| 72 | and writes it to | ||
| 73 | .Fa out . | ||
| 74 | .Pp | ||
| 75 | In the rare case where the compressed content is detached, | ||
| 76 | pass it in via | ||
| 77 | .Fa dcont . | ||
| 78 | For normal use, set | ||
| 79 | .Fa dcont | ||
| 80 | to | ||
| 81 | .Dv NULL . | ||
| 82 | .Pp | ||
| 83 | The only currently supported compression algorithm is zlib: if the | ||
| 84 | structure indicates the use of any other algorithm, an error is returned. | ||
| 85 | If zlib support is not compiled in, | ||
| 86 | .Fn CMS_uncompress | ||
| 87 | always returns an error. | ||
| 88 | .Pp | ||
| 89 | If the | ||
| 90 | .Dv CMS_TEXT | ||
| 91 | bit is set in | ||
| 92 | .Fa flags , | ||
| 93 | MIME headers for type text/plain are deleted from the content. | ||
| 94 | If the content is not of type text/plain, an error is returned. | ||
| 95 | .Sh RETURN VALUES | ||
| 96 | .Fn CMS_uncompress | ||
| 97 | returns 1 for success or 0 for failure. | ||
| 98 | The error can be obtained from | ||
| 99 | .Xr ERR_get_error 3 . | ||
| 100 | .Sh SEE ALSO | ||
| 101 | .Xr CMS_compress 3 , | ||
| 102 | .Xr CMS_ContentInfo_new 3 | ||
| 103 | .Sh STANDARDS | ||
| 104 | RFC 3274: Compressed Data Content Type for Cryptographic Message Syntax (CMS) | ||
| 105 | .Sh HISTORY | ||
| 106 | .Fn CMS_uncompress | ||
| 107 | first appeared in OpenSSL 0.9.8h | ||
| 108 | and has been available since | ||
| 109 | .Ox 6.7 . | ||
| 110 | .Sh BUGS | ||
| 111 | The lack of single pass processing and the need to hold all data in | ||
| 112 | memory as mentioned in | ||
| 113 | .Xr CMS_verify 3 | ||
| 114 | also applies to | ||
| 115 | .Fn CMS_uncompress . | ||
