CHW-5102 EncryptionUnavailable

server-side encryption is not configured; ask an operator to set the required key

Default message: server-side encryption is not configured; ask an operator to set the required key
HTTP status: 500 (server)

Problem. The TOTP or SSO encryption key is missing or malformed and an operation that needed it failed. Cause. CHAINSAW_TOTP_ENCRYPTION_KEY / SSO secret-encryption key is unset or not a 64-char hex string. Fix. Operator must set a valid key — exactly 64 hex characters, e.g. openssl rand -hex 32 — and restart. HTTP 500.
