# keyfork-entropy
Retrieve system entropy, output in hex format. The machine must be running a
kernel with BLAKE2 entropy support and not be connected to the Internet.
## Arguments
`keyfork-entropy [size=256]`
* `size`: Number of bits, must be divisible by 8
## Variables
- `INSECURE_HARDWARE_ALLOWED=1`: Bypass system validation
- `SHOOT_SELF_IN_FOOT=1`: Bypass system validation
## Output
Hex-encoded system entropy, of length `size / 4`
