The Generate ECC Key Pair (OPM, QC3GENECC; ILE, Qc3GenECCKeyPair) API generates a random ECC key pair given a set of domain parameters to be used with elliptic curve cryptographic algorithms such as ECDSA. Information on cryptographic standards can be found in Create Algorithm Context (OPM, QC3CRTAX; ILE, Qc3CreateAlgorithmContext) API. Oct 26, 2016 Generally, there is provided, a method for generating an elliptic curve cryptography key pair that uses two topologically identical pseudo-random number generators operating in parallel and in step with each other. One generator operates in the scalar number domain and the other generator operates in the elliptic curve point domain. Here are the steps to generate an EC private and public key pair: 1. Alice selects an elliptic curve subgroup defined by a set of domain parameters, (p,a,b,G,n,h).

To generate an EC key pair the curve designation must be specified. Note thatJOSE ESxxx signatures require P-256, P-384 and P-521 curves (see theircorresponding OpenSSL identifiers below).

PEM key parsing in Java
The BouncyCastle library provides a simpleutility to parse PEM-encoded keys in Java, to use them for JWS or JWE later.
For Maven you should include the following BouncyCastle dependencies (where1.52 is the latest stable version as of May 2015):
