Pseudo Random Code Generator

Gjrand is a pseudo random number generator of C language. Pseudo random numbers mean that in this random number is not guaranteed to be truly random, only suitable for some places where random requirements are not very high, such as games and similar uses, but not for some very high randomness applications, such as lottery tickets and high security random code generation. Gjrand 3.4.0 Release Note: Gjrand is a programmer's library for pseudo-random numbers. Gjrand l ...

Gjrand is a pseudo random number generator of C language. Pseudo-random numbers mean that in this random number is not guaranteed to be really random, only suitable for some of the random requirements are not very high occasions, such as games and similar uses, but not for some of the very high randomness requirements of applications, such as lottery and high security random code generation? Gjrand 3.4.2 has several library functions with small performance adjustments. The normal distribution of the test program has some significant updates.

PGP itself is a data security product, what security problems does it have? "No data security system is unbreakable," Philzimmermann, author of PGP, said in the PGP document. "PGP is no exception. We look at its security vulnerabilities in order to let users know what will degrade the security of PGP and how to avoid them. Here are the vulnerabilities: passwords or private key leaks, public key tampering, files that you delete are restored, viruses and Trojan horses, physical security is violated (physical security refers to the security of physical resources such as computers) 、...

We know that PGP (pretty) is the most popular kind of encryption software at present, it is a mail encryption software based on RSA public key encryption system. We can use it to keep the message confidential to prevent unauthorized reading, and it can also digitally sign the user's message so that the recipient can be sure of the sender's identity. It allows users to communicate securely with people they have never seen before, without requiring any secrecy to pass the key, because it uses an asymmetric "public key" and "private key" encryption system. But PGP is not a completely asymmetric addition ...

But then he found a problem, the richer his experience, the longer it would be to complete a project or task. Because he had seen too many situations that might have gone wrong and hesitated to choose. Suppose, for example, that he had just thought of writing a piece of code to write a file, and he was beginning to worry about the following series of questions: permissions, locking, concurrency, atomic manipulation 、...
