Re: Use sha256 for password file authentication

[davidcrossey]

I don’t believe sha256 is supported with -u/-U, however you could instead perhaps use .z.pw to carry out custom validation to the effect of:

1. Read your user:sha256 file in the callback when a connection attempt is made
2. Convert the plain text password from the user to sha256
3. Validate the user with 1b (success) or 0b (failure)
