Secure all your accounts with the lightweight and easy to use Key Generator KeyGen tool. All you need to do is choose the password length and what elements you want to include in your password, and click the Generate button.

The system will generate a unique password, and you can copy and paste it wherever you need. Creating a strong password is one of the most important ways to secure your accounts and keep them private. Unfortunately, people have a tendency to reuse passwords or create simple passwords like sequential numbers, birthdates, or their home address. This makes it easy for cybercriminals to access your account and do with it as they please.

It improved security by avoiding the need to have password stored in files, and eliminated the possibility of a compromised server stealing the user's password. However, SSH keys are authentication credentials just like passwords.

Thus, they must be managed somewhat analogously to user names and passwords. They should have a proper termination process so that keys are removed when no longer needed. The simplest way to generate a key pair is to run ssh-keygen without arguments.

In this case, it will prompt for the file in which to store keys. Here's an example:. First, the tool asked where to save the file. SSH keys for user authentication are usually stored in the user's. However, in enterprise environments, the location is often different. Then it asks to enter a passphrase. The passphrase is used for encrypting the key, so that it cannot be used even if someone obtains the private key file.

The passphrase should be cryptographically strong. Our online random password generator is one possible tool for generating strong passphrases. A key size of at least bits is recommended for RSA; bits is better. RSA is getting old and significant advances are being made in factoring. Choosing a different algorithm may be advisable. It is quite possible the RSA algorithm will become practically breakable in the foreseeable future.

All SSH clients support this algorithm. It is based on the difficulty of computing discrete logarithms. A key size of would normally be used with it. DSA in its original form is no longer recommended. This is probably a good algorithm for current applications.

Only three key sizes are supported: , , and sic! We would recommend always using it with bits, since the keys are still small and probably more secure than the smaller keys even though they should be safe as well. Most SSH clients now support this algorithm. Support for it in clients is not yet universal. Thus its use in general purpose applications may not yet be advisable. The algorithm is selected using the -t option and key size using the -b option.

The following commands illustrate:. Normally, the tool prompts for the file in which to store the key. This can be conveniently done using the ssh-copy-id tool. Like this:.
