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, VBA, 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.

Stop letting Excel round your numbers to 15 digits! Get full precision now!
Work with very large numbers in Microsoft Excel without them being automatically rounded. Get full precision up to 32,767 digits.
xlPrecision is an Add-In for Microsoft Excel that provides vastly more precise results from mathematical formulas than Excel provides on its own. xlPrecision allows you to do arithmetic and other work on very large numbers without rounding or truncating your numbers. Don't be held back by Excel's limitation of only 15 significant digits!
xlPrecision also eliminates the stealty binary conversion errors that hide undetected until suddenly making a spreadsheet give an incorrect result.
xlPrecision also empowers you to use much larger (and much smaller) numbers than Excel allows on its own. With xlPrecision, you can use gigantic numbers with over 106 TIMES as many digits as Excel allows, as well as extremely tiny numbers with over 106 times as many zeroes to the right of the decimal.
If you're a programmer, xlPrecision's arbitrary-precision (bignum, multi-precision) arithmetic library functions can be called directly from your own programming code.
If you're a number theory mathematician, you'll enjoy the 2,147,483,648 significant digits (yes, over two billion!) available in a special version of xlPrecision made at the request of a number theorist at a German university.
xlPrecision offers many additional features that take you beyond Excel's capabilities in other ways. Save valuable time with xlPrecision's powerful Excluder functions. View your sorted data at a glance with the exceptional sorting function. Take control of your fractional data with the versatile fraction reducer.
