If you do not enter the dsa keyword, the crypto key generate command generates a DSA key pair by default. To enable SSH, you generate a DSA or RSA host key on the device. The SSH server on the ICX device uses this host DSA or RSA key, along with a dynamically generated server DSA or RSA key pair, to negotiate a session key and encryption method with the client trying to connect to it. Router(config)# crypto key generate rsa general-keys The name for the keys will be: myrouter.example.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. When a host key is generated, it is saved to the flash memory of all management modules. The time to initially generate SSH keys varies depending on the configuration, and can be from a under a minute to several minutes. To disable SSH, you delete all of the host keys from the device.

While the SSH listener exists at all times, sessions can not be started from clients until a host key is generated. Microsoft office 2016 product key online generator software. After a host key is generated, clients can start sessions.

SSHv2 RSA host key format is different between FastIron 07.x.xx, 08.0.00 and 08.0.00a software versions .

• When you upgrade from FastIron 7.x.xx, 8.0.00 to 8.0.00a software version , if RSA key is present in FastIron 7.x.xx or 8.0.00 software version, same size will be regenerated in FastIron 08.0.00a software version. Old SSHv2 host key is retained unless they are cleared by the crypto key zeroize command.
• When you downgrade the FastIron software from version 8.0.00a to 8.0.00 or 07.x.xx, consider the following scenarios:
  • SSHv2 RSA host key created in FastIron 7.x.xx or 8.0.00 software version and retained in FastIron 8.0.00a-- In this case, booting up with FastIron 7.x.xx or 8.0.00 software versions reads the old format SSHv2 RSA host keys and enables the SSHv2 RSA server on the switch.
  • SSHv2 RSA host key created in FastIron 8.0.00a--In this case, booting up with FastIron 7.x.xx or 8.0.00 software versions does not read the new format SSHv2 RSA host keys and SSHv2 server is not enabled on the switch.

SSH host keys created with DSA method is interoperable between FastIron 7.x.xx, 8.0.00 and 8.0.00a software versions.

While Encrypting a File with a Password from the Command Line using OpenSSLis very useful in its own right, the real power of the OpenSSL library is itsability to support the use of public key cryptograph for encrypting orvalidating data in an unattended manner (where the password is not required toencrypt) is done with public keys.

The Commands to Run

Generate a 2048 bit RSA Key

You can generate a public and private RSA key pair like this:

openssl genrsa -des3 -out private.pem 2048

That generates a 2048-bit RSA key pair, encrypts them with a password you provideand writes them to a file. You need to next extract the public key file. You willuse this, for instance, on your web server to encrypt content so that it canonly be read with the private key.

Export the RSA Public Key to a File

This is a command that is

openssl rsa -in private.pem -outform PEM -pubout -out public.pem

The -pubout flag is really important. Be sure to include it.

Next open the public.pem and ensure that it starts with-----BEGIN PUBLIC KEY-----. This is how you know that this file is thepublic key of the pair and not a private key.

To check the file from the command line you can use the less command, like this:

less public.pem

Do Not Run This, it Exports the Private Key

A previous version of the post gave this example in error.

openssl rsa -in private.pem -out private_unencrypted.pem -outform PEM

The error is that the -pubout was dropped from the end of the command.That changes the meaning of the command from that of exporting the public keyto exporting the private key outside of its encrypted wrapper. Inspecting theoutput file, in this case private_unencrypted.pem clearly shows that the keyis a RSA private key as it starts with -----BEGIN RSA PRIVATE KEY-----.

Visually Inspect Your Key Files

It is important to visually inspect you private and public key files to makesure that they are what you expect. OpenSSL will clearly explain the nature ofthe key block with a -----BEGIN RSA PRIVATE KEY----- or -----BEGIN PUBLIC KEY-----.

You can use less to inspect each of your two files in turn:

• less private.pem to verify that it starts with a -----BEGIN RSA PRIVATE KEY-----
• less public.pem to verify that it starts with a -----BEGIN PUBLIC KEY-----

The next section shows a full example of what each key file should look like.

The Generated Key Files

Public key generation in windows. The generated files are base64-encoded encryption keys in plain text format.If you select a password for your private key, its file will be encrypted withyour password. Be sure to remember this password or the key pair becomes useless.

The private.pem file looks something like this:

The public key, public.pem, file looks like:

Protecting Your Keys

Depending on the nature of the information you will protect, it’s important tokeep the private key backed up and secret. The public key can be distributedanywhere or embedded in your web application scripts, such as in your PHP,Ruby, or other scripts. Again, backup your keys!

Remember, if the key goes away the data encrypted to it is gone. Keeping aprinted copy of the key material in a sealed envelope in a bank safety depositbox is a good way to protect important keys against loss due to fire or harddrive failure.

Oh, and one last thing.

If you, dear reader, were planning any funny business with the private key that I have just published here. Know that they were made especially for this series of blog posts. I do not use them for anything else.
