摘要：The concept of digital archives to store long term data has readily increased in past few years. Many social, business and government organizations store their data in digital archives for long time span with many challenges along with its advantages. One of the major and most common problem is to ensure the integrity of data stored in digital archives. Usage of hash algorithms is solution to provide integrity in digital archives. Lots of hash algorithms are available now days but the problem is that usually the organizations are short of resources especially time and memory, so they always look for such algorithm that consumes the least amount of resources providing the security at maximum. So in this work the most commonly used hash algorithms are evaluated for their performance on the basis of time, memory and efficiency with variable data object size. SHA-1, MD-5, RIPEMD-160 and HAVAL-256 are evaluated for performance, being the most commonly used hash algorithms. Results show that MD-5 consume least amount of resources with somewhat questionable security, SHA-1 and RIPEMD-160 are more consistent in behavior with a compromising amount of resource usage and security and HAVAL-256 provides best security with high rate of resource usage.
