Question

Consider a scrambled text file that contains hidden text data that is the same as your evaluation. Explain whatever method you used to decrypt the file and why you think it's the best. Defend your stance. A digital fingerprint was found at the crime scene, and you used WinHex editor to calculate its MD5 hash value. You hid the proof away in a laboratory. After waiting a week to start examining the evidence, you used Autopsy and the SHA-1 algorithm to calculate the hash value. You found that the hash value of the evidence had evolved. Is there a particular reason why the hash value of your proof is different now than it was before?
