Member Function Documentation

generate()

static MWCryptRand::generate (   $bytes,   $forceStrong = false  )

static

Generate a run of (ideally) cryptographically random data and return it in raw binary form.

You can use MWCryptRand::wasStrong() if you wish to know if the source used was cryptographically strong.

Parameters

int	$bytes	The number of bytes of random data to generate
bool	$forceStrong	Pass true if you want generate to prefer cryptographically strong sources of entropy even if reading from them may steal more entropy from the system than optimal.

Returns

string Raw binary random data

generateHex()

static MWCryptRand::generateHex (   $chars,   $forceStrong = false  )

static

Generate a run of (ideally) cryptographically random data and return it in hexadecimal string format.

You can use MWCryptRand::wasStrong() if you wish to know if the source used was cryptographically strong.

Parameters

int	$chars	The number of hex chars of random data to generate
bool	$forceStrong	Pass true if you want generate to prefer cryptographically strong sources of entropy even if reading from them may steal more entropy from the system than optimal.

Returns

string Hexadecimal random data
