/* 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.
