Crypto Tool

Cryptographic operations:

• AES encrypt/decrypt
• RSA encrypt/decrypt
• Hash functions (MD5, SHA1, SHA256)
• Base64 encode/decode
• HMAC generation
• Random string generation

Use builtin_crypto_tool tool with fields:

• operation: one of "encrypt", "decrypt", "hash", "hmac", "random"
• algorithm: encryption algorithm (AES, RSA, MD5, SHA1, SHA256)
• data: data to process (required)
• key: (optional) encryption key or secret
• mode: (optional) for AES: ECB, CBC, GCM (default: CBC)

Returns processed result.
