+# `/sys/tools`
+
+The `/sys/tools` endpoints are a general set of tools.
+
+## Generate Random Bytes
+
+This endpoint returns high-quality random bytes of the specified length.
+
+| Method | Path                         |
+| :----- | :--------------------------- |
+| `POST` | `/sys/tools/random(/:bytes)` |
+
+### Parameters
+
+- `bytes` `(int: 32)` – Specifies the number of bytes to return. This value can
+  be specified either in the request body, or as a part of the URL.
+
+- `format` `(string: "base64")` – Specifies the output encoding. Valid options
+  are `hex` or `base64`.
+
+### Sample Payload
+
+```json
+{
+  "format": "hex"
+}
+```
+
+### Sample Request
+
+```shell-session
+$ curl \
+    --header "X-Vault-Token: ..." \
+    --request POST \
+    --data @payload.json \
+    http://127.0.0.1:8200/v1/sys/tools/random/164
+```
+
+### Sample Response
+
+```json
+{
+  "data": {
+    "random_bytes": "dGhlIHF1aWNrIGJyb3duIGZveAo="
+  }
+}
+```
+
+## Hash Data
+
+This endpoint returns the cryptographic hash of given data using the specified
+algorithm.
+
+| Method | Path                           |
+| :----- | :----------------------------- |
+| `POST` | `/sys/tools/hash(/:algorithm)` |
+
+### Parameters
+
+- `algorithm` `(string: "sha2-256")` – Specifies the hash algorithm to use. This
+  can also be specified as part of the URL. Currently-supported algorithms are:
+
+  - `sha2-224`
+  - `sha2-256`
+  - `sha2-384`
+  - `sha2-512`
+
+- `input` `(string: <required>)` – Specifies the **base64 encoded** input data.
+
+- `format` `(string: "hex")` – Specifies the output encoding. This can be either
+  `hex` or `base64`.
+
+### Sample Payload
+
+```json
+{
+  "input": "adba32=="
+}
+```
+
+### Sample Request
+
+```shell-session
+$ curl \
+    --header "X-Vault-Token: ..." \
+    --request POST \
+    --data @payload.json \
+    http://127.0.0.1:8200/v1/sys/tools/hash/sha2-512
+```
+
+### Sample Response
+
+```json
+{
+  "data": {
+    "sum": "dGhlIHF1aWNrIGJyb3duIGZveAo="
+  }
+}
+```
