Only valid for SignatureSchemes that are compatible with KeyType.

setKey() must be called before with a private key.

void fizz::OpenSSLSignature< Type >::verify ( folly::ByteRange  data, folly::ByteRange  signature  ) const

Verifies that signature is a valid signature over data. Throws if it's not.

Only valid for SignatureSchemes that are compatible with KeyType.

setKey() must be called before.
