SSL Cipher Suites
The SSL standard defines only certain combinations of certificate type, key exchange method,
symmetric encryption, and hash method. Such a combination is called a cipher suite.
Table 10-5
lists the supported cipher suites.
Key Type Select the key type to be used. Choices are:
 RSA—Use this key with the SSH1 and SSH2 protocols.
 DSA—Use this key with the SSH2 protocol.
Create New Keys
Username Enter the name of the user associated with the new key.
Key Type Select the key type to be used for the new key. Choices are:
 RSA—Use this key with the SSH1 and SSH2 protocols.
 DSA—Use this key with the SSH2 protocol.
Bit Size Select the bit length of the new key:
 512
 768
 1024
Using a larger Bit Size takes more time to generate the key. Approximate
times are:
 2 minutes for a 512 bit RSA Key
 5 minutes for a 768 bit RSA Key
 15 minutes for a 1024 bit RSA key
 10 minutes for a 512 bit DSA key
 30 minutes for a 768 bit DSA key
 70 minutes for a 1024 bit DSA key
Note: Some SSH clients require RSA host keys to be at least 1024 bits
long.
