    When to use /dev/random vs /dev/urandom - Unix & Linux Stack …

    Nov 18, 2016 · There is no difference between /dev/random and /dev/urandom; both behave identically. Apple's iOS also uses Yarrow. It doesn't matter, as Wikipedia says: /dev/urandom is just a link to /dev/random and only blocks until properly seeded.

    What are /dev/random and /dev/urandom in Linux? - Linux …

    Feb 20, 2023 · Both /dev/random and /dev/urandom are used for generating random numbers in Linux. Learn more about them.

    /dev/random - Wikipedia

    In Unix-like operating systems, /dev/random and /dev/urandom are special files that serve as cryptographically secure pseudorandom number generators (CSPRNGs). They allow access to a CSPRNG that is seeded with entropy (a value that provides randomness) from environmental noise, collected from device drivers and other sources.

    /dev/random 和 /dev/urandom 的原理 - 知乎 - 知乎专栏

    首先要明确一点， /dev/random 和 /dev/urandom 产生的随机数都是从同一个熵池 ( 主熵池 ) 中提取的，只有当各自的熵池耗尽了，它们的行为才有所不同: /dev/random 阻塞，而 /dev/urandom 没有，但是此时它返回的是用算法计算出来的伪随机数. 一般有个规则， /dev/random 产生的随机数质量高，主要用于一些安全方面，而且，它是阻塞的，对于大部分应用来说，这是不能接受 …

    linux - Is /dev/random considered truly random? - Stack Overflow

    Apr 12, 2011 · The difference between /dev/random and /dev/urandom is that the former will try to maintain an estimate (which means "a wild guess") of how much entropy it has gathered, and will refuse to output more bits than that.

    What is the difference between /dev/random and /dev/urandom?

    Jan 28, 2025 · The biggest difference between the two random number generator files /dev/random and /dev/urandom is the quality of the random data. The source of /dev/random provides a higher quality, at the cost of less data available.

    Myths about /dev/urandom | Discoveries - thomas-huehn.com

    Mar 15, 2014 · /dev/urandom is a pseudo random number generator, a PRNG, while /dev/random is a “true” random number generator. Fact: Both /dev/urandom and /dev/random are using the exact same CSPRNG (a cryptographically secure pseudorandom number generator).

    How to use /dev/random or urandom in C? - Stack Overflow

    Apr 3, 2010 · /dev/random and /dev/urandom are convenient, but not as strong as using a HRNG (or downloading a large dump from a HRNG). Also worth noting that /dev/random refills via entropy, so it can block for quite a while depending on circumstances.

    linux - Should I use “/dev/random” or “/dev/urandom” for large random ...

    Sep 24, 2015 · To recap, when you need maximally random data, use /dev/random. However, if you need a lot of data, you need to use /dev/urandom . In general, use /dev/urandom unless you need the data to be indistinguishable from truly random noise for decades to come.

    Getting Started with Linux‘s Random Number Generators

    Dec 27, 2023 · /dev/random vs /dev/urandom. The most common interfaces for getting random data are /dev/random and /dev/urandom. Let‘s discuss the key differences between them. /dev/random only returns random bytes when the entropy pool has sufficient randomness.
