Tradware BVBA -HIME -Huge Integer Math and Encryption library
Tradware BVBA
HIME stands for Huge Integer Math and Encryption library.
It is a cryptography toolkit for Windows programmers that allows to implement public key encryption, secret key encryption, data security and digital signatures using one of the many one-way secure hash functions in your programs.
Public (asymmetric) key encryption and digital signatures with RSA ; standard version or the CRT (Chinese Remainder Theorem) version.
Secret (symmetric) key encryption with AES (Rijndael) in 3 different block cipher modes or ArcFour (RC4 compatible) (**).
HIME also contains functions for huge prime number generation, factoring and cryptographically secure random number generation (a.o. Blum-Blum-Shub and RSA). True random number data can be retrieved from an internet server.
The Diffie-Hellman key exchange algorithm to securely exchange session keys.
HIME has compression and decompression functions with multiple compression algorithms to choose from.
HIME is thread-safe (re-entrant) for use in multi-threaded applications or concurrent environments. * HIME has functions for easily handling data, arranged as records with fields. * HIME has functions for converting data between various formats: huge integer, Base64, decimal, hex, ascii binary. * HIME has functions for securely erasing disk files and free disk space. * HIMEs huge integer number mathematical, bit manipulation and boolean functions can serve as building blocks for implementing other public key encryption schemes or performing math calculations with arbitrary precision.
HIMEs huge integer math functions are ideal for number theory applications.
A huge integer number in HIME can be hundreds of millions of digits long; 2^31 (2147483648) bits long to be exact. That's over 268 MILLION decimal digits!
HIME is a 32 bits dll, so every programming language that can access a standard Win32 dll can use HIME: C, C++, C#, Visual Basic 5/6, VB.Net, Delphi, PowerBASIC, PureBASIC, Liberty Basic, Euphoria, Java, Macromedia Director (with GLU32)... HIME can be used in MS Office (MS Access, MS Excel, MS Word) (***) using VBA (Visual Basic for Applications). .NET (dot NET) languages can use HIME as an 'unmanaged code dll'.
HIME comes with demo and test programs (including their source code) to show HIMEs performance and as an example of how to use HIME.
Demo code in Visual Basic 5/6, C++, C#, VB.Net, Liberty Basic, Delphi, PowerBASIC and PureBASIC are also included.
HIME was written in PowerBASIC (*) and inline assembler.
HIME is designed to support all Windows operating systems. (tested on Windows 98, XP and Vista)
