server-side validation of the client certificate, and in the negotiation of symmetric password scheme, symmetric call key, the server sent to the customer is no encryption (this does not affect the SSL process security) password scheme. In this way, the two sides of the specific communication content, is to add over the dense data, if there is a third-party attack, access to only encrypted data, the third party to obtain useful information, it is necessary to decrypt the encrypted data, this ti
In daily work, there are many documents that need to be reviewed, signed, and stamped by leaders. As the company's business is carried out, cross-regional and cross-border businesses are becoming increasingly common, and the signature and stamp of leaders become very troublesome, at the beginning, people solve the problem by mailing or fax, but it takes time, manpower, and material resources. Today, with the increasingly in-depth networking, more and more things need to be approved and signed an
The scaling of digital images is a very interesting problem, but also a seemingly simple, but some complex problems. Many friends after having a certain basic knowledge of computer graphics programming, they can design some simple bitmap scaling algorithm. In the field of computer graphics and digital image processing, the problem of digital image scaling has bee

This paper introduces the application of digital signature technology in E-government, the traditional digital signature technology is based on asymmetric cryptographic algorithm, the original text is transmitted in clear text, in this way, the security of the original text is greatly threatened, therefore, In this paper, a digital signature te
equal to the average of the AB voltage value, because it is difficult to ensure that the resistance values of R1 and R2 are completely consistent, the wires also have resistance. Therefore, the calculated result is more likely to be 3.99 or 4.01, rather than 4.00, which leads to an error in our calculation. If the circuit is complicated, the error will gradually accumulate and become larger. In the end, the calculation result is completely meaningless, and it is quite difficult to reduce the ci

Overview
In this chapter, we will study digital signatures, which are the first level to determine the identity of the contact who exchanges messages. We will use code samples to describe the two methods used to identify the message source (one is more difficult and the other is easier ). We will also list the digital signature Algorithms supported by JDK 1.4 and research the classes and

Now people have a digital camera is nothing new, let alone more than 5 million pixel digital camera is gradually become the mainstream. A digital camera can instantly convert images to a computer-recognizable image file format for browsing, sharing, and printing, compared to a conventional camera with film as a photographic medium.

1. What is a digital signature? A digital signature is a sign of your program as your own, and when someone sees the signature, they know it's relevant to you .2. Why digital signatures? The simplest and most straightforward answer: system requirements. Android requires every Android app to be digitally signed to install into the system, meaning that if an Androi

Bob has a public and private key. Bob's public key is public and can be obtained by anyone. But only Bob has his own private key. Both the public key and the private key can be used to encrypt the information separately, and the encrypted information can be decrypted with the other key accordingly. For example, when Susan encrypts information with Bob's public key, she sends it to Bob. Bob gets the message, decrypts it with his private key, and obtains Susan's information. Other people, even i
9.5.3 Digital Signature principledigital signatures are a way to ensure data integrity and originality. A digital signature can provide strong evidence that the data has not changed since the data was signed, and that it can confirm the identity of the person or entity that signed the data.
