http	HTTP API: /sys/audit-hash	docs-http-audits-hash	The `/sys/audit-hash` endpoint is used to hash data using an audit backend's hash function and salt.

/sys/audit-hash

POST

Description

Hash the given input data with the specified audit backend's hash function and salt. This endpoint can be used to discover whether a given plaintext string (the `input` parameter) appears in the audit log in obfuscated form. Note that the audit log records requests and responses; since the Vault API is JSON-based, any binary data returned from an API call (such as a DER-format certificate) is base64-encoded by the Vault server in the response, and as a result such information should also be base64-encoded to supply into the `input` parameter.

Method

POST

URL

`/sys/audit-hash/`

Parameters

• input required The input string to hash.

Returns

```javascript
