It generates all the tables in the NIST format. +3) Compare the generated tables with the original provided tables, e.g. + in Unix, with `diff'. +4) The code is independent of the ENDIANness of the machine. + However, the code casts char pointers to int pointers. + On some platforms, this casting can cause problems. + This will cause malfunctioning of the CBC Monte Carlo tests. + In this case, the compile parameter STRICT_ALIGN should be set to 1. + (Of course this results in slower code.) + + +Changes with respect to v1.0 (= round 1 submission) +--------------------------------------------------- + +1) Removed the parameter blockLen from makeKey() and cipherInit(). + The parameter is still present in the structures keyInstance and + cipherInstance. +2) Removed some calls to sscan(). +3) Corrected the CBC decryption Monte Carlo test code. +4) Provided code for platforms with pointer alignment problems. + +---------------------------------------------------------------------- + +Changes from v2.0 (= round 2 submission) +---------------------------------------- + +Various bug fixes in CBC encryption and decryption mode. + +---------------------------------------------------------------------- + +Changes from v2.2 +----------------- + +-- Moved number of rounds to the keyInstance structure + to make implementation thread-safe +-- Functions used only to generate the Intermediate Value + Known Answer Test are now conditionally compiled + via #define INTERMEDIATE_VALUE_KAT +-- Further optimized for the default 128-bit block size +-- Fixed CBC decryption bug (chained IV was lost if input + and outBuffer were the same) +-- Added padding capability to CBC mode (allows encryption + of any number of octets, not only full blocks) + +---------------------------------------------------------------------- + +Changes from v2.3 +----------------- + +Fixed a small bug in CBC mode. |
