How do I convert my Amazon Elastic Compute Cloud (Amazon EC2) Privacy Enhanced Mail (.pem) file to a PuTTY Private Key (.ppk) file? Or, convert a .ppk file to a .pem file?

1. When you set up SSH, you create a key pair that contains a private key (saved to your local computer) and a public key (uploaded to Bitbucket). Bitbucket uses the key pair to authenticate anything the associated account can access. This two-way mechanism prevents man-in-the-middle attacks. This first key pair is your default SSH identity.
2. Provides an EC2 key pair resource. A key pair is used to control login access to EC2 instances. Currently this resource requires an existing user-supplied key pair. This key pair's public key will be registered with AWS to allow logging-in to EC2 instances. When importing an existing key pair the public key material may be in any format.
3. Generating an SSH key. To generate an SSH key with PuTTYgen, follow these steps: Open the PuTTYgen program. For Type of key to generate, select SSH-2 RSA. Click the Generate button. Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. Type a passphrase in the Key passphrase field.
4. SiteGround uses key pairs for SSH authentication purposes, as opposed to plain username and password. More information on SSH keys is available here. You can generate an SSH key pair in Mac OS following these steps: Open up the Terminal by going to Applications - Utilities - Terminal.

Short Description

I created a new keypair and downloaded it to my mac, then set up a new Amazon Linux AMI server with that keypair and my security group. Connecting to amazon aws linux server by ssh on mac. Ask Question Asked 6 years. Macbook-air$ ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key (/Users/sam/.ssh/id.

PuTTY doesn't natively support the private key format (.pem) generated by Amazon EC2. You must convert your private key into a .ppk file before you can connect to your instance using PuTTY. You can use the PuTTYgen tool for this conversion. This tool, available for both Windows and Unix operating system, can convert keys.

Resolution

Windows - install PuTTYgen

Most Windows operating systems have PuTTY installed. If your system doesn't, download and install PuTTYgen.

Windows - convert a .pem file to a .ppk file

Start PuTTYgen, and then convert the .pem file to a .ppk file. For detailed steps, see Convert Your Private Key Using PuTTYgen.

Windows - convert a .ppk file to a .pem file

1. Start PuTTYgen. For Actions, choose Load, and then navigate to your .ppk file.
   
2. Choose the .ppk file, and then choose Open.
   
3. (Optional) For Key passphrase, enter a passphrase. For Confirm passphrase, re-enter your passphrase.
   Note: Although a passphrase isn't required, you should specify one as a security measure to protect the private key from unauthorized use. Using a passphrase makes automation difficult, because human intervention is needed to log in to an instance or to copy files to an instance.
   
4. From the menu at the top of the PuTTY Key Generator, choose Conversions, Export OpenSSH Key.
   Note: If you didn't enter a passphrase, you receive a PuTTYgen warning. Choose Yes.
   
5. Name the file and add the .pem extension.
   
6. Choose Save.

Unix or Linux - install PuTTY

Install PuTTY, if it's not already on your system.

Important: A PuTTY package is provided by the Extra Packages for Enterprise Linux (EPEL) repository. You must enable the EPEL repository before you install PuTTY.

To install PuTTY, run one of the following commands:

RPM-based

Dpkg-based

Unix or Linux - convert a .pem file to a .ppk file

On the instance shell, run the puttygen command to convert your .pem file to a .ppk file:

Unix or Linux - convert a .ppk file to a .pem file

Run the puttygen command to convert a .ppk file into a .pem file:

Description¶

Creates a 2048-bit RSA key pair with the specified name. Amazon EC2 stores the public key and displays the private key for you to save to a file. The private key is returned as an unencrypted PEM encoded PKCS#1 private key. If a key with the specified name already exists, Amazon EC2 returns an error.

You can have up to five thousand key pairs per Region.

The key pair returned to you is available only in the Region in which you create it. If you prefer, you can create your own key pair using a third-party tool and upload it to any Region using ImportKeyPair .

For more information, see Key Pairs in the Amazon Elastic Compute Cloud User Guide .

Synopsis¶

Aws Generate Key Pair Mac Ssh-keygen Code

Options¶

--key-name (string)

A unique name for the key pair.

Constraints: Up to 255 ASCII characters

--dry-run--no-dry-run (boolean)

--tag-specifications (list)

Ssh Keygen Example

Shorthand Syntax:

JSON Syntax:

--cli-input-json (string)Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string)Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples¶

To create a key pair

This example creates a key pair named MyKeyPair.

Command:

The output is an ASCII version of the private key and key fingerprint. You need to save the key to a file.
