Hello experts,

I had encrypted my password with sha512 but i need the plain text too, for validating the passwords on my script may i know how to do.

leaf password_val {
description “Password. Use of % character must be escaped with (Max Size -127)”;
type tailf:sha-512-digest-string {
length “1…127”;
}
}

is it possible to save hash and string value in same leaf

Most of the time you want to use “length”, “pattern”, and/or “must” statements.

Example:

type string {
      pattern ".*[0-9]+.*" {
        error-message "The password must have at least one digit";
      }
      pattern ".*[a-z]+.*" {
        error-message "The password must have at least one lower case alpha";
      }
      pattern ".*[A-Z]+.*" {
        error-message "The password must have at least one upper case alpha";
      }
      pattern ".*[<>~;:!@#/$%^&*=-]+.*" {
        error-message "The password must have at least one of these symbols: [<>~;:!@#/$%^&*=-]+";
      }
      pattern ".* .*" {
        modifier invert-match;
        error-message "The password must have no spaces";
      }
      length "8..max" {
        error-message "The password must be at least 8 characters long";
      }
    }

If you want to validate the passwords using some code or a script it gets a bit more complicated, as you must add a transform and a validation point.

You can use this demo as a reference on how to do so:


The demo uses a C application to serve the transform callpoint and the validation point. You can of course implement the same type of application in for example Python if that is important.
