# SHA-512 hash (`sha512hash`)

Digest of the SHA-512 hash function (SHA-2 family, 512 bits). It is written as 128 hexadecimal digits. Other 512-bit digests (SHA3-512, Keccak-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`

- Countries: global
- Languages: Common to most languages (common)
- Classification: identifier

## Detection

Regular expression (Python `re`):

```
^[0-9a-fA-F]{128}$
```

## Examples

- `cf83e1357eefb8bdf1542850d66d8007d620e4050b5715dc83f4a921d36ce9ce47d0d13c5d85f2b0ff8318d2877eec2f63b931bd47417a81a538327af927da3e` — SHA-512 hash of the empty string
- `ddaf35a193617abacc417349ae20413112e6fa4e89a97ea20a9eeee64b55d39a2192992a274fc1a836ba3c23a3feebbd454d4423643ce80e2a9ac94fa54ca49f` — SHA-512 hash of the string 'abc'
- `cf83e1357eefb8bdf1542850d66d8007d620e4050b5715dc83f4a921d36ce9ce47d0d13c5d85f2b0ff8318d2877eec2f63b931bd47417a81a538327af927da3` (invalid example) — one hex digit short (127 instead of 128)

## Metacrafter rules
