We would like to contribute the Crypto RSA acceleration optimization from Intel.
The contribution is towards the JEP 8046943 and Bug ID: 8069539.
Please review this patch:
The optimization is achieved through intrinsics for BigInteger squareToLen and mulAdd methods.
We see ~50% improvement for SPECjvm2008 crypto.rsa with this patch.
Nils Eliasson has kindly offered to sponsor this patch.
