# RIPEMD-160 hash (`ripemd160hash`)

Digest of the RIPEMD-160 hash function (160 bits), used for example in Bitcoin addresses. It is written as 40 hexadecimal digits. SHA-1 and RIPEMD-160 digests 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]{40}$
```

## Examples

- `9c1185a5c5e9fc54612808977ee8f548b2258d31` — RIPEMD-160 hash of the empty string
- `8eb208f7e05d987a9b044a8e98c6b087f15a0bfc` — RIPEMD-160 hash of the string 'abc'
- `9c1185a5c5e9fc54612808977ee8f548b2258d3` (invalid example) — one hex digit short (39 instead of 40)

## Metacrafter rules

2 rules: 1 match the field name, 1 match values.

- `ripemd160hash` (data, `basic/crypto.yaml`)
- `ripemd160hash_by_field` (field, `basic/crypto.yaml`)
