)-xr) * (k^ ( -1)) (mod p-1) M is the message to be signed, and H (m) is the hash of M (for example, SHA1) result. (r,s) constitutes the signature of M To verify the signature with the public key: 1. Verification: 0 2. Verification: g^ (H (m)) ≡ (y^r) * (r^s) (mod p) The correctness of signature algorithm proves that: By signature process: H (m) ≡s*k+x*r (mod p-1) According to Fermat theorem: g^ (H (m)) ≡g^ (x*r) *g^ (k*s) (mod p) ≡ ((g^x) ^r) * (g^k) ^s (mod p) ≡ (y^r) * (r^s) (mod p) Reference

computers or different encodings, the data is at risk of conflict. --From Https://zh.wikipedia.org/wiki/Unicode#%E5%AE%9E%E7%8E%B0%E6%96%B9%E5%BC%8F UTFUTF (Unicode Transformation format) means the Unicode conversion formats. For example, if a Unicode file contains only basic 7-bit ASCII characters, if each character is transmitted using a 2-byte original Unicode encoding, the 8 bits of its first byte are always 0. This creates a relati

Using this scenario manager to load a relatively small Terrain elevation map is still relatively effective, but when loading a relatively large Terrain elevation map, the speed is obviously slow, the waiting time for opening the program becomes long, and the frame rate also becomes low. I checked the information ab
