Public key cryptography can be applied as a digital signature. * This digital signature is used in case we need to verify the true self (Identity verification), A fictional character with A B contents are encrypted with a private * key itself. This process, known as the digital signing of data through digital signing, you will be sent to the B * B can verify that the data came from A copy by using the public key of A is a decoder. If you can take off, make sure that it came from A public key of a, but only A decoded private key information sign by today's digital signature of A ..., more enforcement action on Internet (computer science. We began to really fully applied and then removed) in order to confirm the actual identity, for example, in the SSL certificate, which will be sent by digital signature sign to confirm that it is the actual transaction processing will start in Java, it is * .JAR, which has the same sign with a digital signature to ensure that the.ด้ว่า java code in a JAR is genuine. These methods but can do so by using a secret key cryptography, but not because it must be exchanged before, which is a key weakness in the work. Public key cryptography is used better and provide higher security .. what was it, TANU Union did not have the disadvantage. Yes, of course not. ..??? There is a waste of public key cryptography is the speed at which work is low in the range of 100-1000 times the secret key crptography. .. ho .. why? .. why students were late because the Prime number generator right now. .. to find a large number of local value must be based on a very difficult and time-consuming so many applications are not only directly, but are used to find the number of random numbers, and then tests whether or not a particular number instead.Exponential equation in and decode it, is the reason the whole that makes it run slowly. Because the power is that value for praying. Let's see some examples of very shoddy coding, use calculators! Ouch! A q p = 47 = RSA, 71 calculation of value.
