Privacy and data integrity continue to be major issues in Computer Science. Most people have email accounts and other accounts which they access with their usernames and passwords. Also in everyday life people exchange data with one another. Cryptographic Hash Functions (CHFs) accept variable length of messages and transform them into fixed length hash codes called digests. However researchers have uncovered serious security flaws and vulnerabilities in the most widely used CHFs such as Message Digests (MDs) and SHAs (Secure Hash Algorithms). This paper reviewed MD and SHA and proposed a new hash algorithm which is more collision resistant than MD and SHA.
