| 3 | surf \- Simple Unpredictable Random Function | |
| 4 | .SH SYNTAX | |

| 13 | uint32 \fIseed\fR[32]; | |
| 14 | .SH DESCRIPTION | |
| 15 | .B surf | |
| 16 | changes a 384-bit input to a 256-bit output, | |
| 17 | under control of a 1024-bit seed. | |
| 18 | When the seed is secret, | |
| 19 | .B surf | |
| 20 | appears to be indistinguishable from a completely random | |
| 21 | 384-bit-to-256-bit function. | |
