i am implementing ECC encryption in java. without bouncy castle ECC cannot be implemented??? It is possible to implement ECC with JDK1.7 without importing any package like bouncy castle.
Whether JDK1.7 has any predefined method to addition or multiplication of point in elliptic curve with random number ie(Q=KP) where p is point, k is number.
pls clarify the doubt

Yes, I don't believe the JDK currently provides any support for the underlying maths required to implement ECC encryption. It just provides some infrastructure classes for describing points and curves.

thanks for ur reply

i want to implement ECC with help of bouncy castle package. i didnt find any proper documentation . any one know abt bouncy castle package tutorial or documentation link which will be helpful for me!!!! pls clarify

Unfortunately the current documentation consists of what JavaDoc there is. You might also find looking at the source for the EC algorithms BC implements provide some useful information on how the classes operate.

Hi, I am interested in using Bouncy Castle API for ECDSA. Is the api free to use for the commercial purposes?

Yes, BC is distributed under an open source license, similar to that of MIT X11.

It is freely usable in commercial products. We just ask that you mention somewhere in your documentation that you are using it.
