  "definition": "1. A hash that uniquely identifies data. Changing a single bit in the data stream used to generate the message digest will yield a completely different message digest.\n\n2. A digital signature that uniquely identifies data and has the property that changing a single bit in the data will cause a completely different message digest to be generated.\n\n3. A crytpographic checksum, typically generated for a file that can be used to detect changes to the file.. Synonyous with hash value/result.\n\n4. A digital signature that uniquely identifes data and has the property that changing a single bit in the data will cause a completely different message diges to be generated.\n\n5. See Digital Fingerprint\n\n6. The result of applying a hash function to a message.",
