I am creating an exericse for my users, where I am trying to tell them that using mt_rand() is not a good option from security point of view. What I did is that I showed them a normal user who gets a password reset email, the token is gene… Continue reading Usage of Mt_Rand in PHP
Apologies if this seems like a trivial question.
I’ve been learning PRNG and cryptographic basics and I don’t think I’ve found an answer to this question (At least that I understand).
My understanding is that a PRNG has an internal state w… Continue reading Does the permutation cycle of a PRNG change completely with different seeds?
I’m working on a project where I want to generate a set of crypto wallet seed phrases from an existing seed phrase. The reason for this is so that using just the original seed phrase the wallet holder can access multiple connected accounts… Continue reading Security Risks of Deriving Crypto Wallet Seed Phrases Using Deterministically Derived Salt
If I generate a large true random number and I seed a CSPRNG with it, then can the output of this CSPRNG be used anywhere where there is a need for a true random number?
For example, if Alice and Bob both know the seed, then could the outp… Continue reading Randomness of seeded cryptographically secure random number generator

This is about a semi decentralized full open source casino running on the Ethereum blockchain.
For me when I audited the code as for the staff, everything was clear: the gambling games being run should be a profitable operation for the cas… Continue reading How that guy is currently robbing the dice2win casino? (ongoing attack) [closed]
I’m doing some research on PHP’s str_shuffle function, I already asked this question multiply times on StackOverflow but got no answer https://stackoverflow.com/questions/61968859/is-it-possible-to-predict-the-next-output-for-the-str-shuff… Continue reading Security of PHP’s str_shuffle()
Minecraft is a game about exploring procedure-generated worlds. Each world is generated from a particular “seed” value, and sharing this seed value allows others to generate the same world in their own game. Recently, the distributed computing project Minecraft@Home set about trying to find the seed value of the world …read more

When using CSPRNG (crypto secure pseudo random number generation) functions seeding is an important step. So what is the best way to seed a random number function?

Anyone who has ever had to propagate small plants from seed will know that efficiently sowing seed can be a difficult process. Getting a consistent number of seed in each point while achieving any sort of speed is almost impossible, and as a result it becomes a tedious process. If …read more
