Adding two tests: - verify a legacy signature (as before) - verify a hashed signature To make sure that we remain compatible.
Detect if it's a hashed signature based on the SignatureAlgorithm: - Ed = Ed25519(message) -> legacy - ED = Ed25519(Blake2b-512(message)) -> hashed
LoadMessageFile() is used for signing as well as verifying. By introducing a new method to compute the Blake2b-512 hash, we can get rid of the 1GB size limit for the verifying process.

As mentioned in my email, I am willing to continue investing my time and energy into the project. There is still some potential, i.e., creating hashed signatures. As of now, this feature can be considered complete. It would be great if you could review the changes, merge them, and then release them. I have tried to adapt to your coding style as good as possible. If you see improvements, please let me know. |

This PR introduces basic support for verifying hashed signatures. This also removes the 1GB limit for verification. The limits are retained for “legacy” hashes.
