These are the exact actions your AI can choose when you ask it to work with HMAC Signature Validator.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through HMAC Signature Validator.

  1. 01

    Compute hmac

    Ensure the algorithm is either sha256 or sha1. Calculates the HMAC signature for a specific message using a chosen algorithm and secret key

  2. 02

    Verify hmac signature

    Validates a provided signature against a message and secret key using secure constant-time comparison

  3. 03

    Get supported algorithms

    Informs the user of which cryptographic algorithms are available for computation and verification

Activate the Connector, copy your link, and paste it into the client you already use. 3 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of HMAC Signature Validator, so you can see the experience inside your AI.

It does not authenticate your account with HMAC Signature Validator. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ

Questions HMAC Signature Validator owners ask.

  • 01

    What algorithms are supported?

    The server supports SHA256 and SHA1 algorithms. You can use get_supported_algorithms to confirm availability.

  • 02

    How does this prevent timing attacks?

    The verify_hmac_signature capability uses constant-time comparison, ensuring the verification time remains identical regardless of whether the signature is correct or where a mismatch occurs.

  • 03

    Can I generate new signatures?

    Yes, you can use the compute_hmac capability to generate a hexadecimal HMAC signature for any message and secret key.
