Am I able to create key pairs and sign "off-chain" data in the Cadence testing framework? I don't see anything in the crypto contract or the docs about it

no, I mean generating a private key and signing an off-chain message that I can verify in a smart contract
or even signing a message with a key in flow.json
not signing a transactions or adding keys to an account, just signing a piece of data
I don't see anything in the crypto contract for signing things
just verifying
@Cadence Does anyone know?
what exactly would you like to do?
I want to sign a payload in the testing framework and verify it in a smart contract
It is for Circle's
OnChainMultiSig
https://github.com/joshuahannan/flow-usdc/blob/cadence-1-multisig/transactions/onChainMultiSig/add_new_payload.cdc
To execute transactions, they sign a message with the text of the transaction and store the signed text on-chain, then the different signers all have to sign and submit their version of it and once there is enough signatures, the actual transaction can be executed
So I am wondering if it is possible to sign non-transaction data in the Cadence testing framework so it can be submitted to a contract like this
Before, they were just doing it with the Go SDK :https://github.com/joshuahannan/flow-usdc/blob/cadence-1-multisig/lib/go/util.go#L205
go with the flow in this case
but I'd like to do it in Cadence if possibleUnknown User•3mo ago

Just the code that I linked, but the Go code super old and uses an ancient version of Go With the Flow. I have to do this this week, so if it isn't possible in the Cadence testing framework right now, I will just do it in Go

As far as I understand what you're trying to do, I don't think we provide any means to do that at the moment, but that could probably be added
could you please open a feature request issue?
