Proposed fix: [LiteLLM Proxy] UnsafeMasterKeyError "LiteLLM proxy refused to start: the master key is a publicly known default." (sk-1234) / no master key set / empty key
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Generate a strong key (sk-$(openssl rand -hex 32)) and set LITELLM_MASTER_KEY where the runtime reads it (replace an already-exported value; .env does not override existing env). If no LITELLM_SALT_KEY and the DB holds values encrypted with the old key, also set LITELLM_MIGRATE_FROM_MASTER_KEY=<old key> for one boot to re-encrypt.
Option: Set a strong master key (and migrate encrypted values if needed) [evidence: official_recommended_action]
Applies when: Proxies using sk-1234/unset keys
Steps:
1. echo "sk-$(openssl rand -hex 32)"
2. Replace LITELLM_MASTER_KEY wherever it is set
3. If DB stores values encrypted with the old key and no salt key: export LITELLM_MIGRATE_FROM_MASTER_KEY=<old>
4. Restart; remove LITELLM_MIGRATE_FROM_MASTER_KEY after the "Done re-encrypting" log
Expected: Proxy starts and stored credentials remain readable
