Precis (RFC 7564/7613) - A Java Implementation

Since a few months, there are a few new specifications around concerning internationalized strings in application protocols, which obsoletes the old Stringprep specification (RFC 3454).
  • RFC 7564: PRECIS Framework: Preparation, Enforcement, and Comparison of Internationalized Strings in Application Protocols
  • RFC 7613: Preparation, Enforcement, and Comparison of Internationalized Strings Representing Usernames and Passwords
  • RFC 7700: Preparation, Enforcement, and Comparison of Internationalized Strings Representing Nicknames

These are also used by XMPP, especially by the new Address Format specification, RFC 7622 (The local and resource part must conform to Precis profiles).

After working on a Java implementation for Precis for some time, I'd finally like to announce the first release of the open source software, which supports all of the three Precis specifications:

Maven coordinates: 

<dependency>
    <groupId>rocks.xmpp</groupId>
    <artifactId>precis</artifactId>
    <version>0.1.0</version>
</dependency>

Anybody who likes to upgrade the obsolete Libidn's Stringprep class is invited to give it a try.

    Thanks, great post. I find your opinion quite interesting, but the other day I stumbled upon a completely different advice from another blogger, I need to think that one through, thanks for posting.
