Interprets the string `s` in order to generate a key Pair.
This takes a helper function to do the key generation from a phrase, password and
junction iterator.



In this case they are interpreted as HDKD junctions; purely numeric items are interpreted as
integers, non-numeric items as strings. Junctions prefixed with `/` are interpreted as soft
junctions, and with `//` as hard junctions.

There is no correspondence mapping between SURI strings and the keys they represent.
Two different non-identical strings can actually lead to the same secret being derived.
Notably, integer junction indices may be legally prefixed with arbitrary number of zeros.
Similarly an empty password (ending the SURI with `///`) is perfectly valid and will generally
be equivalent to no password at all.

`None` is returned if no matches are found.
Interprets the string ` s ` in order to generate a key Pair . This takes a helper function to do the key generation from a phrase password and junction iterator . In this case they are interpreted as HDKD junctions ; purely numeric items are interpreted as integers non - numeric items as strings . Junctions prefixed with ` / ` are interpreted as soft junctions and with ` // ` as hard junctions . There is no correspondence mapping between SURI strings and the keys they represent . Two different non - identical strings can actually lead to the same secret being derived . Notably integer junction indices may be legally prefixed with arbitrary number of zeros . Similarly an empty password ( ending the SURI with ` /// ` ) is perfectly valid and will generally be equivalent to no password at all . ` None ` is returned if no matches are found .
