7.4.1. The Application/Octet-Stream (primary) subtype

The primary subtype of application, "octet-stream", may be used to indicate that a body contains binary data. The set of possible parameters includes, but is not limited to:

      TYPE -- the general type or category of binary data.  This is
      intended as information for the human recipient rather than for
      any automatic processing.

      PADDING -- the number of bits of padding that were appended to the
      bit-stream comprising the actual contents to produce the enclosed
      byte-oriented data.  This is useful for enclosing a bit-stream in
      a body when the total number of bits is not a multiple of the byte

An additional parameter, "conversions", was defined in [RFC-1341] but has been removed.

RFC 1341 also defined the use of a "NAME" parameter which gave a suggested file name to be used if the data were to be written to a file. This has been deprecated in anticipation of a separate Content-Disposition header field, to be defined in a subsequent RFC.

The recommended action for an implementation that receives application/octet-stream mail is to simply offer to put the data in a file, with any Content-Transfer-Encoding undone, or perhaps to use it as input to a user-specified process.

To reduce the danger of transmitting rogue programs through the mail, it is strongly recommended that implementations NOT implement a path-search mechanism whereby an arbitrary program named in the Content-Type parameter (e.g., an "interpreter=" parameter) is found and executed using the mail body as input.
