Third parties can plug their providers into the Solaris Cryptographic Framework. A third-party provider can be one of the following objects:
Loadable kernel software module, such as an encryption algorithm, MAC function, or digest function
Kernel device driver for a hardware accelerator
The objects from a provider must be signed with a certificate from Sun. The certificate request is based on a private key that the third party selects, and a certificate that Sun provides. The certificate request is sent to Sun, which registers the third party and then issues the certificate. The third party then signs its provider object with the certificate from Sun.
The loadable kernel software modules and the kernel device drivers for hardware accelerators must also register with the kernel. Registration is through the Solaris Cryptographic Framework SPI (service provider interface).
To install the provider, the third party provides a package that installs the signed object and the certificate from Sun. The package must include the certificate, and enable the administrator to place the certificate in a secure directory. For more information, see the Appendix F, Packaging and Signing Cryptographic Providers, in Solaris Security for Developers Guide.
