A family of FLEA-inspired CSPRNGs and Stream Ciphers
...The default BEDBUG configuration alternates the rotation constants unpredictably. These four sets of three values differ between BEDBUG128, BEDBUG256 and BEDBUG512 and were selected, tuned and tested in each case for optimal avalanche, which is never less than 16.5 bits.
BEDBUG has passed stringent industry-standard tests for randomness, including NIST and DIEHARD.
ISC lets you encrypt & decrypt text and files of any type up to 4GB
...After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity.
ISC is a symmetric key encryption system, which means that both the sender and recipient of a message must possess the key.
