What is the main reason the MD5 hash value is added to the end of the evidence file format?     The MD5 value can’t be completely calculated and written until the last data block is processed, therefore only the last evidence file in the series will contain the MD5 value     The MD5 hash is the most extensive hashing EnCase provides and therefore it is at the end to ensure all evidence is appropriately hashed and EnCase does not have to hash twice     The MD5 hash occurs twice in the evidence file. Once at the beginning then at the end to validate that both MD5 hashes match providing integrity for the evidence file     The MD5 hash occurs at the end because the compression of the data allows EnCase to save space for the evidence file and provide integrity of the evidence file
