Random numbers in Linux can be generated from two special files, one/dev/urandom. The other is/dev/random. The principle of generating random numbers is to use the current system's entropy pool to calculate a fixed number of random bits, and then

If you want random data in a Linux/Unix type OS, the standard way to do so is to use/dev/random or/dev/urandom. these devices are special files. they can be read like normal files and the read data is generated via multiple sources of entropy in the

In Apache-tomcat Official document: How to get Tomcat to start faster there are some optimizations at startup, one of which is the "entropy source" (entropy source) strategy used when generating random numbers.He mentions that TOMCAT7 's session ID

In a security system, we usually use securerandom to generate a more secure random number, whereas the algorithm used in the default securerandom is sha1prng.random number generators in LinuxIn the Linux operating system, there is a special device

Linux generates random password methods: Strings/dev/urandom | Grep-o ' [[: Alnum:]] ' | Head-n 30 | Tr-d ' n '; Echo Linux Modify Password Method: passwd Root Then enter the new password two times Root can be replaced by the user who needs to
