Methods summary

`public static`	# `instance( $secret = NULL )`
`public`	# `__construct( $secret = ',!8L_J:UW~l\'ACt:7c05!R9}~>yb!gPP=\|(@FBny\'ao/&-\jVs' )`
`public`	# `__destruct( )`
`public`	# `saveState( $sf = NULL )`
`public`	# `warmup( $secret = NULL )`
`public`	# `seed( $seed = NULL )` Seed P2PEG with some entropy. Seed P2PEG with some entropy.
`public`	# `str( $len = NULL )` Return a random binary string of specified length. Return a random binary string of specified length.
`public`	# `hex( $len = NULL )` Hex encoded string Hex encoded string
`public`	# `text( $len = NULL )` Base64 encoded text for URL Base64 encoded text for URL
`public (int)random`	# `int16( )` Return a random 16 bit integer. Return a random 16 bit integer. Returns (int)random
`public (int)random`	# `int32( )` Return a random 32 bit integer. Return a random 32 bit integer. Returns (int)random
`public (int)random`	# `int( (int)$size $size = NULL )` Return a random integer. Return a random integer. Parameters `$size` number of bytes used to generate the integer [1..PHP_INT_SIZE]. Defaults to PHP_INT_SIZE (4 or 8, depending on system) Ex. If $size == 1, the result is a number from interval [0..255]. If $size == 3, the result is a number from interval [0..16777215]. Returns (int)random
`public (int)random`	# `rand32( )` Pseudo-random 32bit integer numbers generator. Pseudo-random 32bit integer numbers generator. This function produces same result as $this->int32(), but is much faster at generating long strings of random numbers, and uses less entropy as well. Returns (int)random Source http://en.wikipedia.org/wiki/Random_number_generation
`public (int)random`	# `rand64( )` Pseudo-random 64bit integer numbers generator. Pseudo-random 64bit integer numbers generator. Returns (int)random Source http://vigna.di.unimi.it/ftp/papers/xorshiftplus.pdf
`public`	# `servImg( (int)$width $width = 64, (int)$height $height = 64, (str)$meth $meth = 'rand32', (int)$itemSize $itemSize = NULL )` Generate and serve to client a random bitmap image. Generate and serve to client a random bitmap image. This method helps to visually inspect a random number generator (RNG). It is not enough to know how good the RNG is, but it can tell that the RNG is bad or something is wrong. Parameters `$width` the image `$height` the image `$meth` a method of this class to generate data `$itemSize` bits - size of each number or char generated by $meth. Defaults to 8 for string and 32 for int Note Requires the GD Library Inspired by http://boallen.com/random-numbers.html
`public`	# `setSecret( $key )`
`public`	# `dynEntropy( $quick = true )` Quickly get some dynamic entropy. Quickly get some dynamic entropy.
`public`	# `clientEntropy( )`
`public`	# `serverEntropy( )`
`public`	# `filesystemEntropy( $dirs = NULL, $maxRead = 0 )`
`public`	# `serverEEntropy( $autoseed = true )` Server Expensive entropy. Server Expensive entropy. Note: Contains serverEntropy()
`public`	# `networkEntropy( $autoseed = true )`
`public`	# `expensiveEntropy( $autoseed = true )` Since this class is designed to run as quick as posible, this method is not called by default. * You should call this method only in places where speed is not critical (ex. on cron, in a background request) Since this class is designed to run as quick as posible, this method is not called by default. * You should call this method only in places where speed is not critical (ex. on cron, in a background request)

`public`	# `hash( $str, $raw = true )`

`public`	# `strxor( $a, $b )`
`public`	# `env( $n )`
`public`	# `seedRandomDev( $seed = NULL )` Write some random bits to /dev/random or /dev/urandom Write some random bits to /dev/random or /dev/urandom From `man 4 random`: Writing to /dev/random or /dev/urandom will update the entropy pool with the data written, but this will not result in a higher entropy count. This means that it will impact the contents read from both files, but it will not make reads from /dev/random faster.
`public`	# `frand_put_content( $filename, $length = NULL, $append = false )` Write $length bytes of random data to $filename file. Write $length bytes of random data to $filename file. If $length is not specified, write data from internal buffer.
`public true`	# `do_flock( (resource)$fp $fp, (int) $lock, (int) $timeout_ms = 384 )` Lock with retries Lock with retries Parameters `$fp` Open file pointer `$lock` Lock type `$timeout_ms` Timeout to wait for unlock in miliseconds Returns true on success, false on fail Author Dumitru Uzun
`public`	# `flock_put_contents( $fn, $cnt, $block = false )`
`public`	# `flock_get_contents( $fn, $block = false )`
