HIME stands for Huge Integer Math and Encryption library.
It is a collection of functions for Windows programmers that allows to implement RSA public key encryption, AES (Rijndael) and ArcFour (RC4) secret key encryption and digital signatures using the SHA-1, SHA-256 or MD5 Secure Hash Algorithm in your programs.

HIME also contains functions for huge prime number generation, cryptographically secure random number generation (a.o. Blum-Blum-Shub and RSA), Diffie-Hellman key exchange algorithm and huge integer number mathematical operations.

These mathematical functions can serve as building blocks for implementing other public key encryption schemes.

A huge integer number in HIME can be hundreds of thousands of digits long; 2^31 (2147483648) bits long to be exact. That's over 268 MILLION digits! (In contrast, a strong 512-bit encryption key is just 64 digits).

HIME is a dll, so every programming language that can access a dll can use HIME: C, C++, Visual Basic, Delphi, PowerBASIC, PureBASIC, Euphoria, Java,... Even scripting languages like Macromedia Director (with GLU32) can use HIME.

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 programs in Visual Basic 5/6, Delphi and PureBasic are also included.

HIME was written in PowerBASIC and inline assembler.

HIME is available as a precompiled dll with included source code as an option.
