What is IKE?

IKE is a key exchange mode for ISAKMP. IKE is used to securely exchange encryption keys as part of building a VPN tunnel.

IKE supports the following encryption algorithms:

    * DES-CBC
    * IDEA-CBC
    * Blowfish-CBC
    * RC5-R16-B64-CBC
    * 3DES-CBC
    * CAST-CBC

IKE supports the following hash algorithms:

    * MD5
    * SHA
    * Tiger

IKE supports the following authentication methods:

    * Pre-shared key
    * DSS signatures
    * RSA signatures
    * Encryption with RSA
    * Revised encryption with RSA

IKE utilizes the Diffie-Hellman asymmetric cipher for key exchange.

IKE is fully documented in RFC 2409: The Internet Key Exchange (IKE).
