Noob question but I need help

Hi everyone

I'd like to know if your chips are able to fulfills the following requirements

1) the ability to securely generate and store an ECDSA secp256k1 asymmetric keypair

2) the ability to sign messages from the private key of the asymmetric keypair

3) the ability for one to retrieve only the public key of the asymmetric keypair (private key non-extractable)

Can you please point me to all models with the price and also if possible how to configure them?

Thanks

Hello sir,

Unfortunately, we don't have a product that can fulfill all these requests. My recommendation is to please check the NTAG 424 DNA which is a low-cost tag with a high level of security.

Let me add that we do recommend purchasing these products with our partners, please follow the next link: RFID Ecosystem | NXP Semiconductors
