A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the FTP Extensions, 2nd edition Working Group of the IETF.

	Title           : File Transfer Protocol HASH Command for Cryptographic Hashes

   The File Transfer Protocol does not offer any method to verify the
   integrity of a transferred file, nor can two files be compared
   against each other without actually transferring them first.
   Cryptographic hashes are a possible solution to this problem.  In the
   past, several attempts have been made to add commands to obtain
   checksums and hashes, however none have been formally specified,
   leading to non-interoperability and confusion.  To solve these
   issues, this document specifies a new FTP command to be used by
   clients to request cryptographic hashes of files.
