How To generate a SSH key pair using PuTTY Key Generator,
1. Find puttygen.exe in the PuTTY folder on your computer, for example, C:\Program Files (x86)\PuTTY. Double-click puttygen.exe to open it.
2. Accept the default key type, SSH-2 RSA.
SSH-2 is the most recent version of the SSH protocol (and is incompatible with SSH-1). RSA and DSA are algorithms for computing digital signatures
3. Set the Number of bits in a generated key to 2048 bits, if it is not already set with that value.
This sets the size of your key and thus the security level. A minimum of 2048 bits is recommended for SSH-2 RSA.
