Under Windows, SSH key pairs can be generated with the tool PuTTYgen which is part of the PuTTY installation package and also available separately.
- Select: Type of key to generate: SSH-2 RSA
- Fill in: Number of bits in a generated key: 4096
- Press: Generate
- Fill in: your key passphrase
- Fill in: confirm your passphrase
- Press: Save private key
- Press: Save public key
- Please remember the path name where you saved your SSH key files!
- PuTTY and related tools use a special key file format. If you also want to use the same private key just generated above for connecting with ssh (OpenSSH), rsync, or scp (as available in Cygwin, for example), you need to convert and to save the private key again under a different name or location ("Conversions" (main menu) → "Export OpenSSH key" ... "Save").
