For Windows, the software interface is PuTTYgen.exe, whereas, for Linux OS the command-line adaptation is available using SSH commands. The aforementioned public-key cryptosystems principally focus on secure data transmission and digital signatures.Īlthough PuTTYkey collects keys in its native file format i.e.ppk files, the keys can easily be converted to any file format. The key generation utility – PuTTYkey Generator (Links to an external site.) can create various public-key cryptosystems including Rivest–Shamir–Adleman (RSA), Digital Signature Algorithm (DSA), Elliptic Curve Digital Signature Algorithm (ECDSA), and Edwards-curve Digital Signature Algorithm (EdDSA) keys.

While on the other side, Linux OS has the only command-line version that could be accessible using SSH commands. PuTTYgen.exe is the graphical tool on Windows OS. Although originally written for Microsoft Windows operating system, it is now officially available for multiple operating systems including macOS, Linux.

It is one of the components of the open-source networking client PuTTY. PuTTYkey is a key generator tool for creating pairs of public and private SSH keys.
