Crypt::SEAL2 ============ SEAL2 is the second version of the stream cipher SEAL2, designed by Don Coppersmith and Phillip Rogaway. CAVEAT SEAL2 is designed to generate up to 2^48 bytes of output per seed. In 1997, Handschuh and Gilbert showed, however, that the output stream can be distinguished from a random sequence after only seeing roughly 2^34 bytes of output. Thus, it is prudent to avoid using the same seed for more than 2^34 bytes of output. BONUS The C file, _seal2.c, is a standalone SEAL2 implementation. To compile it, type: gcc -Wall _seal2.c A new binary, a.out, will be created. To run the binary, type: ./a.out COPYRIGHT AND LICENSE Copyright (C) 2003 Julius C. Duque.
