The SunEC provider has been enhanced to support 4 additional Brainpool curves as defined in RFC 5639, *Elliptic Curve Cryptography (ECC) Brainpool Standard Curves and Curve Generation*. The corresponding EC domain parameters can be created by using `java.security.spec.ECGenParameterSpec` objects with standard names of brainpoolP256r1, brainpoolP320r1, brainpoolP384r1, and brainpoolP512r1. Note that the SunJSSE provider has not yet been enhanced to support these brainpool curves.
