Per https://www.w3.org/TR/xmldsig-core1-explain/ it is needed for ECDSA support (not secp256k1).

When using SECP256K1 Data, it is important that we need a verify function for verifying our signature data. Otherwise the struct is rendered essen…

We should eventually migrate off OpenSSL to libsecp256k1. At least, start with ECDSA signing. See https://github.com/GemHQ/secp256k1-rb
