Persisting Sensitive Data Documentation Improvements

Hey folks,
The Persisting Sensitive Data IntelliJ SDK documentation has been expanded and overhauled.

It covers real-life scenarios for various types of secure credential storage:

  • storing usernames and passwords,
  • persisting API keys and similar credentials,
  • securely storing binary data.

Additionally, it includes best practices for designing storage in Kotlin with appropriate thread handling.

See also the fully functional Persisting API Keys sample, which combines a settings page with secure API key storage.
