Use OpenSSL_MAC and OpenSSL_MAC_CTX wrappers together with
OPENSSL_TRY to replace manual EVP_MAC resource management in
KMAC::sign(). This eliminates manual EVP_MAC_free/EVP_MAC_CTX_free
calls in every error path.
Add a LibCrypto::Authentication::KMAC helper over OpenSSL.
Add keygen/import/export logic into WebCrypto.
Register KMAC128/KMAC256 operations with SubtleCrypto.
This required multiple changes:
- Make hashes non-copiable because they contain a heap allocated pointer
- Reference classes via `NonnullOwnPtr` only (they are non-copiable)
- Drop all existing hashes implementations
- Use the `OpenSSLHashFunction` base class to implement the same hashes
I was not able to come up with a way to divide this commit into multiple
without increasing the amount of changes.
Nothing breaks with this commit!
