Is there any Aptos wallet with support of message signing and ECDSA?

Describe your question in detail.

Recently, Aptos added support for ECDSA in addition to EdDSA, namely, support of secp256k1 cryptography. My task is to be able to verify signature of a text message, which was made by Aptos wallet, in the code. With Petra wallet, I'm able to achieve that using ed25519 cryptography, but I don't see how to create secp256k1 account in Petra. With custom code using Aptos TS SDK, I'm able to sign and verify using secp256k1, but the process has to be verified against the wallet. Is there any Aptos wallet which would support ECDSA accounts? Maybe some command line toolkit?

I hope this works: https://medium.com/@rudreshkoranne0/building-a-signature-verification-system-for-the-aptos-blockchain-using-go-757346e53a0c

As I have used the aptos_std::ed25519 here in the contract for signarure verification, you can spend time understanding the aptos_std::secp256k1 module.

Thank you, maybe I have not expressed my need clearly. My solution needs to be compatible with the way ecosystem user can sign a message. If it requires some custom code to SIGN a message, it is NOT the way to go. Signature verification is my business, I'm a software developer and I will find a way to verify it. But producing the signature must be done by the wallet software. And thus my question - is there an Aptos wallet which supports ECDSA cryptography for the account?

Ohh, I read it incorrect only. Well I didn't knew anything about that.
