# The security/p5-Crypt-Random port

## p5-Crypt-Random-1.25p2 – cryptographically secure random number generator

## Description

    Crypt::Random is an interface module to the /dev/srandom device found on most
    modern Unix systems. The /dev/srandom driver gathers environmental noise from
    various non-deterministic sources including inter-keyboard timings and
    inter-interrupt timings that occur within the operating system environment.

    The /dev/srandom driver maintains an estimate of true randomness in the pool and
    decreases it every time random strings are requested for use. When the estimate
    goes down to zero, the routine blocks and waits for the occurrence of
    non-deterministic events to refresh the pool.

    The /dev/srandom kernel module also provides another interface, /dev/arandom,
    that does not wait for the entropy-pool to recharge and returns as many bytes
    as requested. /dev/arandom is considerably faster at generation compared to
    /dev/srandom, which should be used only when very high quality randomness is
    desired.
