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
	Author(s)       : A. Bryan, et al.
	Filename        : draft-ietf-ftpext2-hash-01.txt
	Pages           : 16
	Date            : 2011-02-01

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.
