generate()

CryptRand::generate

(

$bytes

)

You can use CryptRand::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

Returns

string Raw binary random data

generateHex()

CryptRand::generateHex

(

$chars

)

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

Parameters

int

$chars

The number of hex chars of random data to generate

Returns

string Hexadecimal random data

initialRandomState()

CryptRand::initialRandomState ( )

protected

Initialize an initial random state based off of whatever we can find.

Returns

string

randomState()

CryptRand::randomState ( )

protected

Return a rolling random state initially build using data from unstable sources.

Deprecated:

since 1.32, unused and does nothing

Returns

string A new weak random state

wasStrong()

CryptRand::wasStrong

(

)

Return a boolean indicating whether or not the source used for cryptographic random bytes generation in the previously run generate* call was cryptographically strong.

Deprecated:

since 1.32, always returns true

Returns

bool Always true
