I've ordered some of these coins now, and have been trying to throw together some code to be able to verify the balance of the coin.
I'm not 100% sure about how the signatures are generated and how to check them. The code I'm using right now is taken from wallet2::import_key_images,
and I basically check using:
crypto::check_ring_signature(hash_input, key_image, pkeys, &signature)
In this case the hash_input would be the hash on the digital certificate.
Could you confirm if this is correct, Smoothie?
Looking forward to getting the coins
Here is the original function header:
bool crypto_ops::check_ring_signature(const hash &prefix_hash, const key_image &image,
const public_key *const *pubs, size_t pubs_count,
const signature *sig)
My code to sign and verify(check) is a modification of the create_ring_signature and check_ring_signature functions.
The way it works is it creates a signature of a single output and key image.
The idea is that it operates as a degenerate ring signature (
only one output is used in creating the "ring signature")
There is a signature of the message between ---start--- and ---end--- tags for each key_image.
Hash is the hash of the message between start and end tags.
Excuse me if I may have posted something incorrectly, it is 5am in Hawaii.
I may likely have to publish a copy of my code that is used to do the process.
