Component Library - AKsha-1


Description

The Secure Hash Algorithm (SHA-1) generates a 160-bit (20-hex-digit) message digest for a given message (String) of < 2^32 bytes length. It is considered secure because it is computationally infeasible to find a message which corresponds to a given message digest, or to find two different messages which produce the same message digest. SHA-1 is used by both the transmitter and intended receiver of a message in computing and verifying a digital signature.

The most common Internet use of the SHA algorithm is to create a hashed version of a password for storage in a database. This means that if the security of the database is compromised, the user passwords are still not available; only the hashed password is visible. AKsha-1 can be called from any valid ActiveX container, such as Visual Basic, ASP, ColdFusion, Visual C++ or Microsoft Office.
