Anthony Bryan strikes again. This time his name is attached to a new standards draft for how to get a hash checksum of a given file when using the FTP protocol. draft-bryan-ftp-hash-00 was published just a few days ago.
The idea is basically to introduce a spec for a new command named ‘HASH’ that a client can issue to a server to get a hash checksum for a given file in order to know that the file has the exact same contents you want before you even start downloading it or otherwise consider it for actions.
The spec details how you can ask for different hash algorithms, how the server announces its support for this in its FEAT response etc.
I’ve already provided some initial feedback on this draft, and I’ll try to assist Anthony a bit more to get this draft pushed onwards.
