The Java programming language includes a class called SecureRandom. Windows programmers can use the Cryptographic Application Programming Interface function CryptGenRandom. On Unix platforms /dev/random and /dev/urandom are commonly used, either programmatically or in conjunction with a program such as makepasswd.

There are proposals for adding strong random number generation to PHP.Ī variety of methods exist for generating strong, cryptographically secure random passwords. An alternative random number generator, mt_rand, which is based on the Mersenne Twister pseudorandom number generator, is available in PHP, but it also has a 32-bit state. Finally the rand function usually uses the underlying C rand function, and may have a small state space, depending on how it is implemented. Also some operating systems do not provide time to microsecond resolution, sharply reducing the number of choices. This increases the number of possibilities, but someone with a good guess of when the password was generated, for example the date an employee started work, still has a reasonably small search space. In the second case, the PHP function microtime is used, which returns the current Unix timestamp with microseconds. # include # include # include int main ( void )

When a password policy enforces complex rules, it can be easier to use a password generator based on that set of rules than to manually create passwords. In fact there is no need at all for a password to have been produced by a perfectly random process: it just needs to be sufficiently difficult to guess.Ī password generator can be part of a password manager.

Note that simply generating a password at random does not ensure the password is a strong password, because it is possible, although highly unlikely, to generate an easily guessed or cracked password. A common recommendation is to use open source security tools where possible, since they allow independent checks on the quality of the methods used. While there are many examples of 'random' password generator programs available on the Internet, generating randomness can be tricky and many programs do not generate random characters in a way that ensures strong security. Random passwords can be generated manually, using simple sources of randomness such as dice or coins, or they can be generated using a computer. A random password generator is software program or hardware device that takes input from a random or pseudo-random number generator and automatically generates a password.
