Some Important Command Lines for Putty in Linux
If you are using Putty on Linux for the first time, you need to know some vital commands in order to use Putty on Linux. I’ve given some commands with details below. Hope it’ll be helpful to you.
PuTTYgen [-t keytype [-b bits] [-q] | keyfile]
[-C new-comment] [-P]
[-O output-type | -p | -l | -L]
[-o output-file]
Where,
-keyfile is Name of existing key file to read when modifying an existing key.
-t keytype is the command Specifies to the type of a new key to generate. Acceptable values include rsa and dsa. rsa1 is also supported to generate legacy SSH-1 keys, but they should never be needed any more.
-b bits command Specifies the number of bits in the key. For DSA keys, 1024 is a decent size. For RSA keys, 2048 or even 4096 bits are recommended.
-q command Suppresses messages about progress during key generation.
-C new-comment command Specifies comment to describe the key. The comment does not impact the operation of the key. The comment can be specified for new keys or for existing keys to change their comment. Typically the comment would be used to identify the key owner, but since any value can be specified, it cannot really be relied upon.
-P is the command to Requests to change the key’s passphrase. The tool will prompt for a new passphrase. It is not possible to specify a passphrase on the command line. The passphrase will be used to encrypt the private key.
–old-passphrase-file file is the command to Specify a file from which to read the old passphrase of the key. This is only needed if manipulating an existing key that is protected by a passphrase.
