Abstract

   This memo updates the ODETTE File Transfer Protocol, an established
   file transfer protocol facilitating electronic data interchange of
   business data between trading partners, to version 2.

   The protocol now supports secure and authenticated communication over
   the Internet using Transport Layer Security, provides file
   encryption, signing, and compression using Cryptographic Message
   Syntax, and provides signed receipts for the acknowledgement of
   received files.

   The protocol supports both direct peer-to-peer communication and
   indirect communication via a Value Added Network and may be used with
   TCP/IP, X.25, and ISDN-based networks.
