hi guys, im trying to test a signature verification in my foundry test and i would like to provide the signature from the outside as a string, but obviously i have to convert it to bytes first. What is the correct way to do it? i constantly run into: ECDSA: invalid signature length so obviosuly bytes("signature") is not working.

thx in advance

You should use bytes for signatures (And why shouldn't you?)
you need to properly ask first

what's the problem with using uint as sort of unique identifiers , like NFTs?

What problem?

what's a signature first of all? I am not clear on this one
doesn't it means the signing of a tx we do in metamask?

Public key cryptography

like how does that work under the hood, in simple terms

u use private key to sign a message

Go back to the basics

I mean would the update significantly affect the old tutorials about smart contracts?

it's in the foundry tests. I hardcoded the signatures, the solution was actually prefixing it with hex.

it's still bytes

yes trying to, I was at the basics anyways
not significantly, but some changes will affect otc
ofc
