Pem

SSH public key file format as specified in RFC4716. SSH private key file format must be PEM. Keysmy-key-pair.pem (Windows). Save the private key file in a safe place. From the computer where you downloaded the private key file, generate an SSH2 fingerprint from the private key file. The output should match the fingerprint that's.

Generating the Public Key - Windows 1. At the command prompt, type the following: openssl rsa -in rsa.private -out rsa.public -pubout -outform PEM 2. The public key is saved in a file named rsa.public located in the same folder. Generating the Private Key - Linux 1. Open the Terminal. Navigate to the folder with the. Back to PSCP, users are required to use the private key they generated while converting the.pem file to the.ppk file. Converting a.pem file to a.ppk using PuTTYgen may now seem simple. The above information also briefs users on using PuTTY’s SSH client to connect virtual servers with local machines.

  • 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.
  • I have a.pem file containing my private key. However, a BitBucket deployment key has this format: ssh-rsa.

This article explains public key authentication in general. You may want to see guide to setting up public key authentication instead.

Do not confuse your user key pair used for authentication with host public key verification. Learn about all SSH key types.

Public key authentication is an alternative means of identifying yourself to a login server, instead of typing a password. It is more secure and more flexible, but more difficult to set up.

In conventional password authentication, you prove you are who you claim to be by proving that you know the correct password. The only way to prove you know the password is to tell the server what you think the password is. This means that if the server has been hacked, or spoofed, an attacker can learn your password.

Public key authentication solves this problem. You generate a key pair, consisting of a public key (which everybody is allowed to know) and a private key (which you keep secret and do not give to anybody). The private key is able to generate signatures. A signature created using your private key cannot be forged by anybody who does not have that key; but anybody who has your public key can verify that a particular signature is genuine.

So you generate a key pair on your own computer, and you copy the public key to the server under a certain name. Then, when the server asks you to prove who you are, WinSCP can generate a signature using your private key. The server can verify that signature (since it has your public key) and allow you to log in. Now if the server is hacked or spoofed, the attacker does not gain your private key or password; they only gain one signature. And signatures cannot be re-used, so they have gained nothing.

There is a problem with this: if your private key is stored unprotected on your own computer, then anybody who gains access to that will be able to generate signatures as if they were you. So they will be able to log in to your server under your account. For this reason, your private key is usually encrypted when it is stored on your local machine, using a passphrase of your choice. In order to generate a signature, WinSCP must decrypt the key, so you have to type your passphrase.

This can make public-key authentication less convenient than password authentication: every time you log in to the server, instead of typing a short password, you have to type a longer passphrase. One solution to this is to use an authentication agent, a separate program which holds decrypted private keys and generates signatures on request. WinSCP can use PuTTY’s authentication agent, called Pageant. When you begin a Windows session, you start Pageant and load your private key into it (typing your passphrase once). For the rest of your session, you can start WinSCP any number of times and Pageant will automatically generate signatures without you having to do anything. When you close your Windows session, Pageant shuts down, without ever having stored your decrypted private key on disk. Many people feel this is a good compromise between security and convenience.

There is more than one public-key algorithm available. The most common are RSA and ECDSA, but others exist, notably DSA (otherwise known as DSS), the USA’s federal Digital Signature Standard.1

To generate a key pair, use the PuTTYgen application.

You can start PuTTYgen directly from Authentication page of Advanced Site Settings dialog. If you start PuTTYgen this way, WinSCP will automatically pick up the generated key.

Different file formats are used to store SSH-2 private keys. WinSCP supports PuTTY format, as authors of PuTTY claim that it is the best one.

WinSCP also recognizes (but does not accept) the other two formats (OpenSSH and ssh.com), and it can convert the keys to PuTTY format for you. To convert the key file you can also use /keygen command-line switch or PuTTYgen application.

This section describes how to generate and manage keys for both symmetric and asymmetric algorithms. Asymmetric algorithms require the creation of a public key and a private key. Java generate random encryption key. The public key can be made public to anyone, while the private key must known only by the party who will decrypt the data encrypted with the public key.
