A sheepdip computer is used only for virus-checking. The term 'sheepdip' refers to a process where a computer, separate from a network, is used to scan software or data for malware before it is introduced to the main network. This is done to ensure that any potential viruses or malicious code are identified and dealt with in a controlled environment to prevent them from infecting other systems.

This concept ensures that the integrity of the evidence is maintained and documented at each stage in the handling process, including collection, transportation, storage, and presentation in court.

The MD5 algorithm produces a hash value that is 128 bits long. When represented as a hexadecimal string, each of the 128 bits is represented by 4 bits, resulting in a 32-character string. Therefore, the fixed-length checksum of an MD5 hash is 32 characters long.
