Topic: Signing hash via ecc
We are using wc_ecc_sign_hash and wc_ecc_verify_hash to authenticate parties with each other.
How does the actuall ecc_key`s size affect the security of this process? We're currently using a keysize of 32. Is this too less? Should we use bigger keys?
And what's the most efficient curve algorithm that could be used for the keys to have sign / verify work as fast as possible? We're currently using the default one.
