A comparison of key designs shows concrete risks and fixes: webhook URLs leak far more because they look like regular links and end up in logs; researchers scrape public sites and find webhooks as the most common exposed SaaS secret. Cracking experiments recover weak JWT symmetric secrets for about 2% of tokens offline, and over 11,000 GitHub SSH keys are factorable or reused. Recommendations: generate keys server-side, use fixed prefixes for discovery, avoid unnecessary JWTs, and prefer 20+ random characters.
