Explanation

MD5 (Message Digest Algorithm 5) produces a fixed-length hash of 128 bits (16 bytes), typically represented as a 32-character hexadecimal string. For comparison: CRC-32 produces a 32-bit checksum (not a true cryptographic hash), SHA-1 produces a 160-bit digest, and SHA-512 produces a 512-bit digest. In digital forensics, MD5 is widely used to verify the integrity of evidence by generating a hash before and after acquisition to confirm no data was altered.
