HIME dll

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.

DeepCoder

With DeepCoder you can protect your privacy when you are sending confidential e-mails and/or files over the internet and when you are storing private files on your computer. DeepCoder is a program to encrypt, decrypt and/or digitally sign e-mails and files using secret keys (passwords) or public keys. It can be used with any e-mail program or wordprocessor program. No plug-ins are required. DeepCoder in a nutshell: - Very easy to use and very straightforward! - DeepCoder works with any POP3 e-mail client (like Outlook, Outlook Express, Eudora, Pegasus, ...) or a browser for webmail (Yahoo! mail, Hotmail, ...) to encrypt and decrypt e-mails. - DeepCoder works with any wordprocessing program to encrypt and decrypt (parts of) text. - DeepCoder can encrypt and decrypt files. - DeepCoder can create encrypted and compressed archives with multiple files and an optional textmessage. - DeepCoder uses secret key encryption (AES/Rijndael) and public key encryption (RSA). - Digital signatures: DeepCoder can digitally sign your e-mails and files. You can even have files signed by multiple people. - DeepCoder can create self-extracting files so you can send encrypted files and/or textmessages to people who do not have DeepCoder installed. - Encrypt and/or decrypt files by simple drag-and-drop. - Decrypt files by double-clicking. - Encrypt and/or decrypt textmessages by pressing a hotkey (or many other ways...) E-mail DeepCoder can encrypt your e-mail message and makes them unreadable to anyone, except the person you send the mail to. Such a 'message' can be ordinary text, but it can also include one or more files. Files If you know that other people can easily get access to your computer and your files and you don't want them to read your files, DeepCoder is just the tool for you. With DeepCoder you can encrypt your files so that nobody but you (or someone else who has the key) can read your files.

HIME: Huge Integer Math and Encryption

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.
