algorithm for the signature. Common algorithms are specified in Java reference. Use the Signatur instance to initSign(PriKey) initialize the signature or initVerify(pubkey) to initialize the authentication. The input that uses the Signatur instance update(bytes) requires the data to be signed. Use the Signatur instance sign() or verify() implement the signature or authentication. Note that the former returns byte[] and the latter returns a Boolean. Base64Currently, there are th

I,Public KeyEncryptionAssume that I have two numbers: 1 and 2. I like the number 2 and keep it. I won't tell you (Private Key), and I will tell you that 1 is my public key. I have a file that cannot be viewed by others. I use 1 for encryption. Someone else finds this file, but he does not know that 2 is the decryption private

article will discuss in detail the security and possible risks and vulnerabilities of USB keys currently used by online banking in China from a technical point of view. Of course, the security of an online banking system involves a lot of theoretical knowledge, not only the comprehensive knowledge of the university course cryptography, but also the latest product developments of

the difference is indeed not small. Below, I give the QQ millions on-line technology realization plan, and in order to expand, talk about the large-scale on-line system load balance mechanism design.QQ game from the login and game process, QQ game, also divided into at least three types of servers. They are:First layer: Login/account Server (login server), responsible for authenticating the user identity, to send the initial information to the client, from the QQ chat software Packaging Common

original texts that correspond to one ciphertext, however, the other plaintext is completely meaningless, so this does not affect the actual security) Symmetric encryption algorithm: DES, 3DES. These algorithms use the same key for encryption and decryption, featuring high efficiency. 3DES is actually the DES algorithm encrypted three times, because the computer

First Step encryption:1. The meaning of encryptionIf the software is not encrypted it is easy to be anti-compilation caused by the source code leaks, to find out the address of the server and indirectly received attacks, such as a series of problems.2.
