Signing and verifying a message using ECDSA sometimes fails #1898
What is the current behavior and expected behavior?
Expected behaviour: I should be able to generate a KeyringPair that signs messages using the ECDSA algorithm and verify the signatures against the message + the KeyringPair's public key
Current behaviour: This works most of the time, approx 99/100 times, but sometimes the verification fails.
What is the motivation for changing the behavior?
I'm working on a project that relies on being able to sign and verify data from the KeyringPair or from Polkadot wallets so I want to be able to rely on this functionality.
Please tell us about your environment:
I'm using @polkadot/keyring, @polkadot/util and @polkadot/util-crypto at the latest version as of writing (12.6.1).
