Package

cl-isaac.

Source

isaac-32.lisp.

Function: generate-next-isaac64-block (ctx)
Package

cl-isaac.

Source

isaac-64.lisp.

Function: init-common-lisp-random-seed (&key is64)

Initialize random seed from CL:RANDOM. If :is64 t, use ISAAC-64 context.

Package

cl-isaac.

Source

cl-isaac.lisp.

Function: init-kernel-seed (&key is64)

Initialize Kernel seed from /dev/arandom on BSD systems, /dev/urandom on Linux systems, or return an error. If :is64 t, use ISAAC-64 context.

Package

cl-isaac.

Source

cl-isaac.lisp.

Function: init-null-seed (&key is64)

Initialize null seed, useful for testing but not production. If :is64 t, use ISAAC-64 context.

Package

cl-isaac.

Source

cl-isaac.lisp.

Function: init-self-seed (&key count is64)

Initialize cryptographically strong self-seed starting with a kernel-seed as first round, and then performing a scramble on the bits and modular addition between the resulting values and a new kernel-seed on each additional count. :count n (default: 1), a real number, instructs the self-seed to repeat n times. If :is64 t, use ISAAC-64 context.
