It differs from the standardized SHA3-512, which uses different padding. It is written as 128 hexadecimal digits. Other 512-bit digests (SHA-512, SHA3-512, BLAKE2b-512 and Streebog-512) have the same length, so the value alone does not tell them apart: use the field name or context. - Parent datatype: `hash` - Personal data (PII): no - Categories: Cryptographic identifiers (cryptography) - Countries: global - Languages: Common to most languages (common) - Classification: identifier ## Detection Regular expression (Python `re`): ``` ^[0-9a-fA-F]{128}$ ``` ## Examples - `0eab42de4c3ceb9235fc91acffe746b29c29a8c366b7c60e4e67c466f36a4304c00fa9caf9d87976ba469bcbe06713b435f091ef2769fb160cdab33d3670680e` โ€” Keccak-512 hash of the empty string - `18587dc2ea106b9a1563e32b3312421ca164c7f1f07bc922a9c83d77cea3a1e5d0c69910739025372dc14ac9642629379540c17e2a65b19d77aa511a9d00bb96` โ€” Keccak-512 hash of the string 'abc' - `0eab42de4c3ceb9235fc91acffe746b29c29a8c366b7c60e4e67c466f36a4304c00fa9caf9d87976ba469bcbe06713b435f091ef2769fb160cdab33d3670680` (invalid example) โ€” one hex digit short (127 instead of 128) ## Metacrafter rules 2 rules: 1 match the field name, 1 match values. - `keccak512hash` (data, `basic/crypto.yaml`) - `keccak512hash_by_field` (field, `basic/crypto.yaml`) ## Supported by tools - `metacrafter` ## Sources - wikipedia: - other: ## Quality Score 85/100.
