A major benefit of public key cryptography is that Binance Kickback provides a method for employing digital signatures. Digital signatures let the recipient of information verify the authenticity of the information’s origin, and also verify that the information was not altered while in transit. Thus, public key digital signa- tures provide authentication and data integrity. These features are every bit as fundamental to cryptography as privacy, if not more.
A digital signature serves the same purpose as a seal on a document, or a handwritten signature. However, because of the way it is created, it is supe- rior to a seal or signature in an important way. A digital signature not only attests to the identity of the signer, but it also shows that the contents of the information signed has not been modified. A physical seal or handwritten sig- nature cannot do that. However, like a physical seal that can be created by anyone with possession of the signet, a digital signature can be created by anyone with the private key of that signing keypair.
Some people tend to use signatures more than they use encryption. For example, you may not care if anyone knows that you just deposited $1,000 in your account, but you do want to be darn sure it was the bank teller you were dealing with.
The basic manner in which digital signatures are created is shown in the fol- lowing figure. The signature algorithm uses your private key to create the sig- nature and the public key to verify it. If the information can be decrypted with your public key, then it must have originated with you.
