Support for RSA Signatures

J2SE 1.3.0 includes a cryptographic service provider to support the widely used RSA signatures for electronically signing software that is delivered over the Web. Standard RSA certificates are supported, including those from VeriSign and Thawte.

Prior to J2SE 1.3.0, Java platform users who wanted to use RSA certificates needed to write their own RSA service providers or purchase an RSA service provider from a third party. Now an RSA provider is included as a standard part of J2SE 1.3.0.
