Huge Integer Math and Encryption library.- A cryptography toolkit for Windows with public key and secret key encryption, data security and digital signatures with one-way secure hash functions.- Public (asymmetric) key encryption and digital signatures with RSA.

Optional PKCS#1 v1.5 RSA padding.- Secret (symmetric) key encryption with AES (Rijndael) or ArcFour (RC4 compatible).- Hash functions: SHA-512, SHA-256, SHA-1, MD5, CRC32.- FIPS 198 HMAC.- Huge prime number generation, factoring and cryptographically secure random number generation (a.o. Blum-Blum-Shub).

True random number data from an internet server.- Diffie-Hellman key exchange algorithm.- Compression / decompression with multiple compression algorithms.- Thread-safe for use in multi-threaded applications.- Functions for converting data between various formats: huge integer, Base64, decimal, hex, ascii binary.- Securely erasing disk files and free disk space.- 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.- Number theory applications. - A huge integer number in HIME can be hundreds of millions of digits long; 2^31 (2147483648) bits long. MILLIONS of decimal digits! - HIME is a 32 bits dll.

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)...- .NET (dot NET) languages can use HIME as an 'unmanaged code dll'.- 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 versions.
