`ipsw download ipsw --kernel` now fetches firmware keys from theapplewiki and decrypts encrypted kernelcaches inline. Unencrypted members in the same IPSW pass through unchanged. - pkg/img4: DecryptPayload reuses Payload.GetData for decompression, removing the duplicate LZSS/LZFSE branches. - pkg/kernelcache: ParseImg4Data switches to img4.ParsePayload and exports ErrEncryptedKernelCache so callers can detect the missing-key case via errors.Is. - internal/commands/extract: new keyed remote path with all-or-nothing preflight; the encryption-status peek lets unencrypted variants succeed even when the wiki has no entry for them. closes #1193
