OK, there was a small typo in my key. Apparently when pasting to file the first letter was cut off and it started with sh-rsa instead of. The tip below provides a basic overview of public-key authentication, explains how to generate and upload keys to the Secure Shell server, and shows how to. This article will go over how to enable SSH authentication using an OATH-TOTP app in addition to an SSH key. Logging into your server via.

If you are connecting to an OpenSSH server, you may want to use the OpenSSH format to simplify the process involved with setting up the remote server with your public-key file. If you are connecting to a VShell server, you can use either format since VShell accepts them both. Public- and private-key files are placed in a local folder on the machine where the client application resides, usually with the filename " Identity ".
The public key can be uploaded to a VShell server at the end of the Key Generation wizard process, or at any time later through the Session Options dialog. Use the following steps to upload an existing public-key file:. In the Properties dialog, find the Use identity or certificate file section, and press the file browser button ….
Navigate to the key file you want to use in the Select Identity Filename dialog. Press the Upload button to place the public key on the Secure Shell server. This is also where you can change the passphrase for your key. Although there may be server implementations that support the public-key subsystem, those connecting to servers that aren't VShell will typically need to use manual methods to place their public-key files on the server to meet the server's requirements.

Generally, the user's home directory or any file or directory containing keys files should not be writable by anyone else. Otherwise someone else could add new authorized keys for the user and gain access.
Private key files should not be readable by anyone else. SSH keys are very useful, but can lead to problems if they are not properly managed. They are access credentials just like user names and passwords. If they are not properly removed when people leave or systems are decommissioned, no-one may any longer know who really has access to which systems and data.
Many large organizations have ended up having millions of SSH keys. It is recommended that keys used for single sign-on have a passphrase to prevent use of the key if it is stolen or inadvertatly leaked. The ssh-agent and ssh-add programs can be used to avoid having to enter the passphrase every time the key is used. Generally all keys used for interactive access should have a passphrase. Keys without a passphrase are useful for fully automated processes.
They allow shell scripts, programs, and management tools to log into servers unattended. This is often used for backups and data transfers between information systems. The copy-id tool does not automatically add command restrictions to keys.
Using command restrictions is highly recommended when the key is used for automating operations, such as running a report for fetching some files. Anyone having more than a few dozen servers is strongly recommended to manage SSH keys.
Not managing the keys exposes the organization to substantial risks, including loss of confidentiality, insertion of fraudulent transactions, and outright destruction of systems. The copy-id tool can be dangerous. It can easily accidentally install multiple keys or unintended keys as authorized.
The logic for choosing which key to install is convoluted. Extra authorized keys grant permanent access. They can later be used to spread attacks host-to-host, and the more keys there are, the higher the risk. It also violates all regulatory compliance requirements. Just add it. If this option is not provided, this adds all keys listed by ssh-add -L. Note: it can be multiple keys and adding extra authorized keys can easily happen accidentally! This can be used for overriding configuration settings for the client.
However, according to some sources MacOS To install it using Homebrew, use the following command. You need to have the brew command installed. The following command will install it using MacPorts. You need to have the port command installed. The following command can be used to install a Mac version directly.

The model assumes the private key is secured. Adding a passphrase to encrypt the private key adds a layer of security good enough for most user-based cases. For automation purposes, key management software and practices apply since the private key stays unprotected otherwise. The basic instructions for Linux, macOS, and Windows are outlined below. Generating new keys overwrites the current ones by default. However, stating a new name for the keys saves them to different files. Create the directory using the mkdir command for storing the new key pair:.
Change the permissions to The output prints out a message, indicating the command ran successfully. Next, the program asks where to save the file:. If you have existing keys you want to keep, enter a new file name. Otherwise, press Enter to save in the default location. If any keys already exist in this location, the program overwrites the data. Finally, enter a passphrase to secure the key. Press Enter and confirm the passphrase once more when requested. The password is required any time you use the key for authentication.
Lastly, the program prints out information about where the keys are stored. Additionally, a digital and a graphic representation print to the console too. Use the Windows search box to find cmd and open the Command Prompt window. Note: Command not working? Don't worry. There are other ways to generate the keys. Try following our detailed tutorial for generating an SSH key pair on Windows If you set up a specific location for the keys, type in the path now.
Otherwise, press Enter to save the keys in the default path. If keys exist in this location, the output asks to confirm the overwrite. Type Y to confirm and press Enter to continue the setup. Enter the passphrase to encrypt the private key. Re-enter the same passphrase and press Enter to finish generating the key pair. For multiple users and keys, copy each new key onto a new line. Save the file and close. 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.
