DeserializationError for PublickKey using Google Auth

[inthedark122]

Hi all
Can someone help me with verifying the signature from the React app in the Rust app?
I'm using Aptos wallet with Google Auth. I'm sending public_key: public_key: account.publicKey.toString(),
and then trying to parse it in the rust app: let public_key = Ed25519PublicKey::from_encoded_string(&form.public_key)?;
But I get an error: DeserializationError

google auth (assume you mean login with google) use a special type of account called keylelss account, it's not using ed25519 as the standard eoa wallet, you can read more here https://aptos.dev/en/network/blockchain/accounts#generalized-authentication

you need to do some replacement like this https://x.com/kaitox2024/status/1919385213869666365

Yes, I'm using Google Auth because my clients have issues with this

I found that it calls https://github.com/aptos-labs/aptos-core/blob/devnet/crates/aptos-crypto/src/traits.rs#L89 let bytes_out = ::hex::decode(str); but for unknown reason I still have issue issue with my public key

My public key from testnet: 0x031b68747470733a2f2f6163636f756e74732e676f6f676c652e636f6d204b8595585b5b77dcf8586af4e7b2f8a7ed690c474c1cb3e579064a6e67bd911f

str is 1b68747470733a2f2f6163636f756e74732e676f6f676c652e636f6d204b8595585b5b77dcf8586af4e7b2f8a7ed690c474c1cb3e579064a6e67bd911f

we don't have a rust implementation for verifying keyless signature, but here's a ts version
