Secure Hash Algorithm (SHA) is one of the most important hash functions in cryptography. Several security protocols such as Pretty Good Privacy (PGP) use hash functions to provide integrity for messaging. The chaotic hash function is new trend in cryptography. This paper focuses on designing a new hash function based on chaotic system which enhances the security of hash function since the proposed hash function has a good avalanche effects and more collision resistant compared with SHA-1. The used chaotic system is built on Lorenz system. It is implemented using c# programming language and bcccrypto open source package.
