A Prime256v1 public key consists of two points (x, y). These can be encoded in different formats. I don't mean e.g. DER, but compressed, uncompressed and hybrid format. At least I found those here: [1].
I want to create a SHA256 fingerprint of a public-key. I would convert them to uncompressed format (32 bytes), concat them and hash the result:
SHA256(x_uncompressed || y_uncompressed)
Is this correct? I have found very little information online. I think converting them to the same format is important, otherwise the same key could produce different results, but I am not sure to what format I should convert them.
Thank you very much.
