Work with key codes and access restriction settings by generating or updating digital keys based on RSA and DSA algorithms. It creates both public and private key pairs, opens and modifies existing keys and saves optional copies. Generation of SSH-1(RSA), SSH-2 RSA is also possible.

From the developer:
PuTTYgen is an open source RSA and DSA key generation utility. The program allows you to generate a public or private key pair, you can load an existing private key file and save the generated key. It also can generate a SSH-1(RSA), SSH-2 RSA and SSH-2 DSA.
You may want to check out more software, such as Remote Asset Tracker, RAS Monitor or Inspyder InSite Trial, which might be similar to PuTTYGen.
