Write your own signature method: 1, pay attention to the first and last two words: the first and last two words are the most important, because they determine the overall effect of the name. Write the first and last words, and the signature is half the battle.

2. Exaggerate the strokes appropriately and relax: the signature has nothing to do with calligraphy. Of course, if you have a certain calligraphy foundation, you will naturally be more skilled in grasping the structure of words, and sometimes you don't have to stick to the rules. Exaggerate some vertical and horizontal strokes appropriately to make the whole harmonious and beautiful.

3. Smart Lian Bi can simplify the complex: sometimes, some parts of a casually written word will make people feel good, because inadvertently, Lian Bi makes the whole word smart.

The function of signature is 1 to prevent impersonation. Others can't forge the signature of the message, because the private key is only known to the signer, so others can't forge the correct signature result. Require private key holders to keep their private keys safe.

2. Anti-tampering For digital signatures, the signature and the original file have formed a mixed whole data, which cannot be tampered with, thus ensuring the integrity of the data.

3. Denial-proof digital signature can identify identity, and it is impossible to pretend to be forged. The signer cannot deny his signature. In order to prevent the receiver from denying it, in the digital signature system, the receiver is required to return the message signed by itself to the other party or the third party, or the third party arbitration mechanism is introduced.
