	GATE_Comparison Freeware

Use short and easy to remember passcodes to defeat peeking, wiretapping, keylogging, phishing and dictionary attack without the restrictions of lowercase, uppercase, numbers & special characters ! Fixed passwords have the advantage of easy to remember, one time passwords have the advantage of hard to hack, GATE passcode is a fixed passcode to the user, but from the hackers' perspective, it changes every time, GATE passcodes have the best worlds.

	GATE_For_PM Freeware

The purpose of GATE_For_PM is to protect passwords from exposure, especially the master passwords of password managers. With GATE_For_PM, user's GATE passcodes are interception-resistant, which means even if someone is watching / keylogging / video recording the user log into the GATE system, user passcode will not be exposed.

	CMATH for C++ Builder Shareware

CMATH is a comprehensive library for complex-number arithmetics and mathematics, both in cartesian and polar format (single and double precision). The implementation in machine code ensures superior speed, accuracy, and safety, as compared to other available complex class libraries. All CMATH functions may be called from C or C++. For the Embarcadero / Borland C++ compiler series (RAD Studio, or BC++ Builder, BC++).

	CMATH for Delphi Shareware

CMATH is a comprehensive library for complex-number arithmetics and mathematics, both in cartesian and polar format (single, double, and extended precision). The implementation in Assembly language ensures maximum speed, accuracy, and safety, far superior to the unit Complex coming with Delphi. Contains the 32-bit Units for P8 (Intel Core2Duo, AMD64x2 or higher) and for P4 (full FPU accuracy; back-compatible to 486DX) as well as 64-bit P8.

	CMATH for Lazarus / FreePascal Shareware

CMATH is a comprehensive library for complex-number arithmetics and mathematics. 1. High-performance implementation in machine code leads to superior speed. 2. Accuracy and safety are greatly enhanced. 3. Individually optimized treatment of Single and Double accuracy.

	CMATH for Visual C++ Shareware

CMATH is a comprehensive library for complex-number arithmetics and mathematics, both in cartesian and polar format (single and double precision). The implementation in machine code ensures superior speed, accuracy, and safety, as compared to other available complex class libraries. All CMATH functions may be called from C or C++. For MS Visual C++ 5, 6, 2003, 2005, 2008, 2010, or 2012 (32-bit and 64-bit).
