* <p>You can find an example library that can be used for this at https://github.com/bitcoin/secp256k1</p>
|

*
|

* <p>To build secp256k1 for use with bitcoinj, run
|
||||
* `./configure --enable-jni --enable-experimental --enable-module-schnorr --enable-module-ecdh`
|
||||
* `./configure --enable-jni --enable-experimental --enable-module-ecdh`
|

* and `make` then copy `.libs/libsecp256k1.so` to your system library path
|
||||
* or point the JVM to the folder containing it with -Djava.library.path
