HIME Huge Integer Math and Encryption
Encryption functions (public key/ secret key) and huge integer math functions HIME is a Huge Integer Math and Encryption library.
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) secret key encryption and digital signatures using the SHA-256 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) 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,...
HIME comes with demo and test programs (including their source code) to show HIMEs performance and as an example of how to use HIME.
A demo program in Visual Basic 5/6 is also included.
HIME was written in PowerBASIC and inline assembler.
Here are some key features of "HIME Huge Integer Math and Encryption":
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) (**).
Hash functions: SHA-512, SHA-256, SHA-1, MD5, CRC32 (**).
HIME also contains functions for huge prime number generation 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.
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.
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!
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, Delphi, PowerBASIC, PureBASIC, 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 programs in Visual Basic 5/6, Delphi and PureBasic are also included.
HIME was written in PowerBASIC (*) and inline assembler.
