The editor will share with you what the digital signature refers to. I hope you will gain a lot after reading this article. Let's discuss it together.

A digital signature is actually similar to a different physical signature written on paper. However, what is a little different is that this digital signature uses the technology in the field of public key encryption mainly to identify digital information. Similar to the type of ssl certificate, this digital signature generally has two operations, one of which is used for signature and the other is used for verification.

The sender of digitally signed information can produce a digital string that others cannot forge, mainly because this digital string will still be a proof, what does it prove? It is the fact that the sender of the message sends the real existence of the message. Digital signature certificate, to put it simply, this digital signature is as simple as some data attached to the data unit, or it is possible that the password of the data unit has been exchanged. So this is a way to prevent others from being falsified, the main thing is to confirm the source and integrity of the data unit, probably to protect the data. The information in electronic form can be signed, that is, a digital signature, so that the signed information can be transmitted in the network without fear of being cut off. The main methods to obtain digital ciphers are public key cryptosystem and private key cryptosystem. There will be corresponding digital signature certificates, of which the former is a more common one, mainly ordinary digital signatures and special digital signatures.

The main function of a digital signature is to encrypt the information and transmit it to the receiver together with the original text. The same is true of SSL. If it is the same, it means that the information received is complete and has not been modified during transmission, otherwise the information has been modified, so the digital signature can verify the integrity of the information.
