Our previous blog post discussed securely generating a random integer or string in PHP.Since it was published, we began working on a free and open source library to expose PHP 7's CSPRNG functions in PHP 5 projects, which we call random_compat, with many great contributions from other PHP developers.. But also, we've discovered that the volume of bad information about random number generators. Appending CSPRNG generated salt to a string that needs to be hashed. Reading about generating salt using Cryptographically Secure Pseudo-Random Number Generator (CSPRNG). This salt then will be appended to a string that needs to be hashed. However, the salt generated by CSPRNG function (for PHP I'm using openssl_random_pseudo_bytes) is actually.

Developing CSPRNG in pure PHP was actually a lot harder than someone might think since there is no single function in PHP that can be called to guarantee enough entropy that will work on all web hosts and there is a ton of misinformation on the PHP website. This is partly the fault of PHP itself for being an incredibly flexible cross-platform tool so that it can run on a wide variety of hosts.

  4. The operating system you have PHP 5 installed on already ships a CSPRNG, and you should be using that for all your randomness, unless you know you can use it, or performance is a concern. You should be using random_int(), random_bytes(), or openssl_random_pseudo_bytes(). However, if you must implement a userspace CSPRNG, then this can be done by simply using an AES library (E.G.: libsodium.

Is there any other way to.

There are a lot of answers to this question, but none of them leverage a Cryptographically Secure Pseudo-Random Number Generator (CSPRNG).. The simple, secure, and correct answer is to use RandomLib and don't reinvent the wheel.. For those of you who insist on inventing your own solution, PHP 7.0.0 will provide random_int() for this purpose; if you're still on PHP 5.x, we wrote a PHP 5. Use a CSPRNG When a password reset token is issued, send both values to the user, store the selector and a SHA-256 hash of the random token in the database. Use the selector to grab the hash and User ID, calculate the SHA-256 hash of the token the user provides with the one stored in the database using hash_equals() secure: 64-bit, non-reproducible, CSPRNG, uses php_random_bytes() internally. By default, XorShift128+ is used. It can generate 64-bit values, is used by major browsers, and is fast and reliable. On the other hand, MT19937 is retained for compatibility. secure is practically equivalent to random_int(), but can be used to shuffle arrays and strings. Also, since it is an object, it is easy.

It also has an unnecessary second parameter that confuses the usage of the API PHP 7 introduces two new functions that can be used for CSPRNG: random_bytes and random_int. The random_bytes function returns a string and accepts as input an int representing the length in bytes.

This CSPRNG is not reseeded automatically when a process calls fork(). This can result in situations where two different processes can return similar or identical keys and compromise the security of the system. The approach this project has chosen to mitigate this vulnerability is.

php - Appending CSPRNG generated salt to a string that

In the PHP hashing system, by using CSPRNG, a salty password that seems accidental will be created. PHP hashing functions, consider salt as a password parameter. These passwords are safe from hackers, rainbow tables and any leakage. Because a salty password is creating for each password and there is no reverse to the original text. The security level of this password is tested multiple times. The PHP 7 solution is to use random_bytes(), and if you're using PHP 7 by the time you read this blog post, please do use that for random byte strings.
