If you don’t find your key in that list, then first add and then assign it.Īt the time of connecting to the cloud server, first of all, you need to tell PuTTY to use it for utilizing your newly created RSA key pair. You can choose the public key from the given list of keys at the time of creating a cloud server.


PuTTYgen is used to generate public or private key pair for creating SSH keys. 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 PuTTYgen 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 – PuTTYgen 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.
