Abstract
This research developed a head and tail (HT) technique that added complexity on implementing MD5 and SHA-1 algorithm for hashing passwords using fragmentation and concatenation processes. The Head and Tail technique uses multiple hashing on password plain text and bit manipulation on combined password digest to produce a 512-bit hash. Frequency (Monobit) Test gives an average computed p-value of 0.72 when HT is applied to MD5 and 0.73 to SHA-1 while Frequency Test within the block resulted to an average p-value of 0.854 and 0.806 for MD5 with HT and SHA-1 with HT respectively. On the other hand, in the run test, an average p-value of 0.40 is achieved for MD5 with HT and an average p-value of 0.54 for SHA-1 with HT. The HT technique has greatly improved the randomness of the password digest.
