feat: Verifying signatures

Open enitrat opened this issue 1 year ago • 4 comments

In this example, we will demonstrate how we can use check_ecdsa_signature to verify if (signature_r, signature_s) is a valid ECDSA signature for the given public_key

Solidity reference: https://solidity-by-example.org/signature/

@HansBhatia Are you still working on it?

Be aware that in version 2.1.0 there's a way to verify Ethereum signature. See secp256_trait.cairo

@julio4 I am not.

I would like to take this up, In this we can generate the signed message through a script, and then perform the functions such as verify signature and recover public key right ?

Can I take up this?

Yes true, closing this now @RajeshRk18. I mistook this issue for another.
