[[Source]<br>](https://github.com/ripple/rippled/blob/master/src/ripple/rpc/handlers/Random.cpp "Source")
The `random` command provides a random number to be used as a source of entropy for random number generation by clients.
## Request Format
An example of the request format:
<!-- MULTICODE_BLOCK_START -->
*WebSocket*
```
{
"id": 1,
"command": "random"
}
```
*JSON-RPC*
```
{
"method": "random",
"params": [
{}
]
}
```
*Commandline*
```
#Syntax: random
rippled random
```
<!-- MULTICODE_BLOCK_END -->
The request includes no parameters.
## Response Format
An example of a successful response:
<!-- MULTICODE_BLOCK_START -->
*WebSocket*

"id": 1,
"result": {
"random": "8ED765AEBBD6767603C2C9375B2679AEC76E6A8133EF59F04F9FC1AAA70E41AF"
