Insecure randomness: java.util.Random / Math.random in a security context

What it detects

Insecure randomness: java.util.Random / Math.random in a security context: a cryptography check run by the textscan analyzer.

Evidence

The matching source path, line, and bounded code observation produced by the native rule.

Remediation

Use java.security.SecureRandom for tokens, salts, session IDs, and keys. java.util.Random / Math.random are statistically predictable.

Limitations

This check is limited to the applicability and evidence delivered by textscan. Review the evidence in context; a match is a finding input, while confidence and policy determine its disposition.
