NetIQ Certificate Server is automatically installed when you install eDirectory. Certificate Server provides public key cryptography services that are natively integrated into eDirectory and that allow you to mint, issue, and manage both user and server certificates. These services allow you to protect confidential data transmissions over public communications channels such as the Internet.
If you are unfamiliar with public key cryptography concepts, see Public Key Cryptography Basics.
MD2 and MD5 signature algorithms for RSA encryption are not supported with eDirectory 9.1 and above.
