To convert a key into OpenSSH's private key format: To change the passphrase on a key (you will be prompted for the old and new passphrases): Puttygen -t rsa -b 2048 -C "my home key" -o mykey.ppk Puttygen -t rsa -C "my home key" -o mykey.ppk To generate an SSH-2 RSA key pair and save it in PuTTY's own format (you will be prompted for the passphrase): The following options do not run PuTTYgen as normal, but print informational messages and then quit:ĭisplay a message summarizing the available options.ĭisplay the fingerprints of the PuTTY PGP Master Keys, to aid in verifying new files released by the PuTTY team. If this option is not specified, puttygen will assume you want to overwrite the original file if the input and output file types are the same (changing a comment or passphrase), and will assume you want to output to stdout if you are asking for a public key or fingerprint. Specify the file where puttygen should write its output. If no output type is specified, the default is private. This option is not permitted for SSH-1 keys. Save an SSH-2 private key in ssh.com's format. Save an SSH-2 private key in OpenSSH's format. All fingerprinting algorithms are believed compatible with OpenSSH. For SSH-2 keys, the public key will be output in the OpenSSH format, which is a single line (` ssh-rsa AAAAB3NzaC1yc2.'). For SSH-1 keys, this output format behaves identically to public. Save the public key only, in a format usable by OpenSSH. For SSH-2 keys, the public key will be output in the format specified by RFC 4716, which is a multi-line text file beginning with the line ` - BEGIN SSH2 PUBLIC KEY -'. For SSH-1 keys, the standard public key format will be used (` 1024 37 5698745.'). This will either be the standard SSH-1 key format, or PuTTY's own SSH-2 key format. Save the private key in a format usable by PuTTY. Specify the type of output you want puttygen to produce. In the third phase, puttygen saves the key or information about it. This is automatic when you are generating a new key, but not when you are modifying an existing key. Indicate that you want to change the key's passphrase. This comment string will be used by PuTTY to identify the key to you (when asking you to enter the passphrase, for example, so that you know which passphrase to type). Specify a comment string to describe the key.

In the second phase, puttygen optionally alters properties of the key it has loaded or generated. Suppress the progress display when generating a new key. Specify the size of the key to generate, in bits. The acceptable values here are rsa and dsa (to generate SSH-2 keys), and rsa1 (to generate SSH-1 keys). This private key file can be in the (de facto standard) SSH-1 key format, or in PuTTY's SSH-2 key format, or in either of the SSH-2 private key formats used by OpenSSH and ssh.com's implementation. Note that generating a key requires random data (from /dev/random), which can cause puttygen to pause, possibly for some time if your system does not have much randomness available. In the first phase, puttygen either loads or generates a key. Then, it optionally makes modifications to the key (changing the comment and/or the passphrase) finally, it outputs the key, or some information about the key, to a file.Īll three of these phases are controlled by the options described in the following section. Firstly, it either loads an existing key file (if you specified keyfile), or generates a new key (if you specified keytype). Click Open and enter your login credentials.When you run puttygen, it does three things.In the Auth tab (located in SSH), browse for and select your private key.In the Session tab, enter the Host Name and select SSH as the connection type.

Saving the public key with the extension .pub can help to distinguish between the two keys.
