Crypto Utility

This tool represents a cryptographic utility for AES-256-style operations. It accepts plaintext as the data to process, an optional 64-character hex key, and an optional mode parameter (encrypt or decrypt, default encrypt). When mode is encrypt and no key is supplied, the worker must generate a new high-entropy 64-character hex key and include it in the structured result. When mode is decrypt, the key is logically required and plaintext should contain the ciphertext to decrypt. The worker must treat plaintext as opaque raw data and not add commentary. The tool output must be a single JSON object that strictly validates against the system-provided structured output schema referenced by schemaArtifactId, with only the allowed keys and correct types and enums.
