isValidSignature(_:for:)
Verifies an elliptic curve digital signature algorithm (ECDSA) signature on a block of data over the P-521 elliptic curve.
ECDSA.swift:519func isValidSignature<D>(_ signature: P521.Signing.ECDSASignature, for data: D) -> Bool where D : DataProtocol Parameters
Returns
A Boolean value that’s true if the signature is valid for the given data; otherwise, false.
