PasswordPolicy

The rules a password must meet (NIST SP 800-63B): the fewest characters, from 8 (15 where a password is the only factor), the most, at least 64, and whether a new password is checked against a list of breached ones. No composition rules and no expiry, as NIST says.

Security; not ordered; since Jadpo 0.1.0.

Make one

Build one from its fields, PasswordPolicy { min_length: ... max_length: ... check_breached: ... }.

Its parts keep these rules; a value that breaks one fails with the rule's name:

• min_not_above_max: min_length <= max_length

Fields

Text, JSON and storage

It has no single text form, so text.from and text.parse don't take it. JSON sends an object of its parts.

It is stored in 3 columns, each named for the field, _ and its suffix. This is {"min_length":8,"max_length":256,"check_breached":false}:

Shown to people

text.format(value, locale:) shows it to people in their locale.

With locale: Locale.en_gb:

Operations

It has the contract's own operations: text.format, json.read, json.write and ==. It isn't ordered, so < and sorting don't take it. Every standard type meets one contract says how they work.
