In Wireshark, where are credentials configured for decryption or filtering?

• A. Edit → Preferences
• B. Tools → Credentials
• C. View → Preferences
• D. Analyze → Options

Answer: (B)

Credentials for decryption or filtering are configured in Wireshark’s dedicated credentials manager, accessed via Tools → Credentials. This central dialog is designed to store login information and tokens that decoders may need to decrypt traffic or to apply authenticated filters. It keeps credential handling separate from general protocol settings, which live under Edit → Preferences (and similar preference paths), and from capture/analysis options, which live under Analyze. By placing credentials in the Tools menu, Wireshark can reuse them across different decoders and sessions, making it easier to work with protected traffic without re-entering credentials each time.
