Password-Policy like functionality for SSH Key Generation

Hello,

i would like to have a function in DVLS to manage settings for SSH Key generation as administrator.

It should be possible to define:

• The algorithm that is used for key generation
• Key Size
• Key format for public and private keys
• If a passphrase is mandatory

In addition to that it would be great to define the Algorithm that is used for SSH-Key Passphrase encryption.
