/* LibTomCrypt, modular cryptographic library -- Tom St Denis
|
||||
*
|
||||
* LibTomCrypt is a library that provides various cryptographic
|
||||
* algorithms in a highly modular and flexible manner.
|
||||
*
|
||||
* The library is free for all purposes without any express
|
||||
* guarantee it works.
