Free Security & Privacy Software
PuTTYgen
Simon Tatham created PuTTYgen, a key generation tool. It is used to generate cryptographic key pairs for usage in secure communication protocols like SSH (Secure Shell). PuTTYgen provides users with the ability to generate, maintain, and convert public and private keys, hence improving the security of data transfers between clients and servers. The software is particularly useful for creating secure connections in a variety of computing settings.
