The namespace keys are UI-language-independent constants, defined in includes/

NET, making use of 120-bit random numbers for its session IDs (represented by 20-character strings [10]) that can provide a very good effective entropy, and as a result, can be considered long enough to avoid guessing or brute force attacks.

The session ID must be unpredictable (random enough) to prevent guessing attacks, where an attacker is able to guess or predict the ID of a valid session through statistical analysis techniques.
