The name HIME comes from Huge Integer Math and Encryption library.

Here are some key features of "HIME":

· 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. Optional RSA padding according to PKCS#1 v1.5 .
· Secret (symmetric) key encryption with AES (Rijndael) in 3 different block cipher modes or ArcFour (RC4 compatible)
· Hash functions: SHA-512, SHA-256, SHA-1, MD5, CRC32.
· Keyed-Hash message authentication code (HMAC) according to FIPS 198.
· 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, EBasic (Emergence Basic), Euphoria, Java, Macromedia Director (with GLU32)...
· 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, EBasic (Emergence Basic) and PureBASIC are also included.
· HIME was written in PowerBASIC (*) and inline assembler.

Limitations:

· Nag Screen
· 10 seconds delay time before execution

What's New in This Release: [ read full changelog ]

· hi_HIMEParams_LoadFromFile : This function retrieves a set of HIME internal parameters and data from a file. This allows HIME to start up faster.
· hi_HIMEParams_SaveToFile : This function allows you to store the current set of HIME internal parameters to a file.
