NamedCurve (JOSH API Document)

java.lang.Object
- org.bouncycastle.crypto.tls.NamedCurve

```
public class NamedCurve
extends Object
```
RFC 4492 5.1.1
The named curves defined here are those specified in SEC 2 [13]. Note that many of these curves are also recommended in ANSI X9.62 [7] and FIPS 186-2 [11]. Values 0xFE00 through 0xFEFF are reserved for private use. Values 0xFF01 and 0xFF02 indicate that the client supports arbitrary prime and characteristic-2 curves, respectively (the curve parameters must be encoded explicitly in ECParameters).
