Date: Mon, 20 Mar 1995 16:15:25 -0500 (EST) From: "Donald E. Eastlake 3rd" <[email protected] To: [email protected] Subject: application/CyberCash MEDIA TYPE NAME: Application MEDIA SUBTYPE NAME: CyberCash REQUIRED PARAMETERS: none (CyberCash messages encode within themselves a format version number) OPTIONAL PARAMETERS: none ENCODING CONSIDERATIONS: CyberCash messages are currently in 7 bit US-ASCII with limited line lengths. Some message types are quite readable but many include within them some digital signature information and many have large portions encrypted. This signature and/or encrypted information is essentially binary and is currently base64 encoded in certain fields. In the future, CyberCash messages may be extended to include a more extended set of byte values in which case a Content-Transfer-Encoding of other than 7bit will be required. SECURITY CONSIDERATIONS: The CyberCash system is designed so that a secure channel is not required other than for privacy reasons. Someone observing CyberCash messages may be able to tell who is transfering funds to whom and for what reason but they will not be able to misappropriate funds based on these messages unless they can break the cryptosystems used. Use of CyberCash messages within a secure envelope will usually eliminate all privacy concerns other than basic traffic analysis. No currently defined CyberCash messages has any "executable" material. PUBLISHED SPECIFICATION: The specifications for this content-type are proprietary. They are specified by CyberCash, Inc. The registration of this content-type is intended only to provide a convention for labeling this proprietary data type within the MIME/HTTP environment and does not specify any details about the content format or semantics, except to refer to the software and specifications provided by CyberCash, Inc.
