Asymmetric password encryption mechanism uses RSA encryption algorithms to encrypt the password being transmitted.
To perform this RSA encryption, configure your JRE with a suitable Java Cryptography Extension (JCE) provider. The configured JCE provider should be capable of supporting the “RSA/ECB/OAEPWithSHA1AndMGF1Padding” or “RSA/NONE/OAEPWithSHA1AndMGF1Padding” transformation. SAP jConnect ships a FIPS 140-2 certified JCE Provider with the product and it is used by default.
You can use the JCE_PROVIDER_CLASS connection property to specify an alternate JCE provider. There are a number of commercial and open source JCE providers that you can choose from. For example, the “Bouncy Castle Crypto APIs for Java” is a popular open source Java JCE provider. If you choose not to specify the JCE_PROVIDER_CLASS property, SAP jConnect uses the default FIPS 140-2 certified bundled provider.
