Consider a scrambled text file with hidden text data that is the same as your evaluation. To what extent do you feel confident in the efficacy of the method you used to decrypt the file, and why did you settle on that method in particular In your justification, please consider the following. You used WinHex editor to calculate the MD5 hash value of a digital fingerprint taken from the crime scene. You hid the proof away in a laboratory. After waiting a week to begin investigating, you used Autopsy and the SHA-1 algorithm to calculate the hash value. Specifically, you found that the hash value of the evidence has evolved. Is there a particular reason you think the hash value of your evidence would be different now than it was before?
