thanks for the review!

the registry is here:
http://www.iana.org/assignments/hash-function-text-names/hash-function-text-names.xml

how does this work for you?

The server-FTP process MUST use the "Hash Function Name" as defined in
the IANA registry named "Hash Function Textual Names" for possible
supported hash algorithms.

in context:

When replying to the FEAT command [RFC2389], a server-FTP process that
supports the HASH command MUST include a feature line indicating that
the HASH command is supported, along with a list of all supported hash
algorithms, including the currently selected hash algorithm, in a
semicolon separated list. The server-FTP process MUST use the "Hash
Function Name" as defined in the IANA registry named "Hash Function
Textual Names" for possible supported hash algorithms.
