Nov 23, 2011 router(config)#crypto key generate rsa usage-keys label router-key The name for the keys will be: router-key Choose the size of the key modulus in the range of 360 to 2048 for your Signature Keys. Choosing a key modulus greater than 512 may take a few minutes. How many bits in the modulus 512: 1024. Oct 05, 2007 Generating public keys for authentication is the basic and most often used feature of ssh-keygen. Rsa 2048 bit encryption. Ssh-keygen can generate both RSA and DSA keys. RSA keys have a minimum key length of 768 bits and the default length is 2048. When generating new RSA keys you should use at least 2048 bits of key length unless you really have a good reason for. Ssh user@ciscoswitch returns: sshrsaverify: RSA modulus too small: 512 768 bits keyverify failed for serverhostkey Solution The modulus of the ssh RSA key pair on the switch is too small. If you have access, generate a new key pair on the switch with a larger modulus. Login with ssh protocol version 1 (ssh space dash. One needs to define domain-name before it's possible to generate SSH keys: sw1(config)#crypto key generate rsa% Please define a domain-name first. Sw1(config)#ip domain-name test.net sw1(config)#crypto key generate rsa The name for the keys will be: sw1.test.net Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Github generate multiple ssh keys. PIX software may generate a self-signed RSA key on bootup that is 768 bits, even if a user-generated key already exists. Vulnerability scanners can identify this as a security risk. When the default RSA key is deleted, the ASA will regenerate a 768-bit RSA key on a subsequent bootup even if a user-created RSA key exists.

One needs to define domain-name before it's possible to generate SSH keys:
Why is domain-name required? Is the domain-name used in key generation?

- You can get around it if you use labels of the keys:
I'm guessing its just a way to track the keys within the file system, if you look at the below output:
If you were to cat the public key it would also probably have the hostname + domain name as metadata. - lrb,
ok, I understand now. ssh-keygen supports similar functionality:

I see it only as a label. Without knowing how the specific vendor did it, I would not know.
The formula for 'RSA' for example, is designed for using numbers as input. Whether or not a vendor translates this into part of what determines a pseudo random number, for example, I dunno.
The reason I only think it's a label for the key (so you can keep track of it).
Look at this command:
[h=2]crypto key pubkey-chain rsa[/h]
That command allows you to make your own keys, from the CLI. one command is required to label the key in some way, with either an IP address, or a name.

If you look here you can see here, it says either specify a label, or it uses the domain name:

Keep in mind the disclaimer that I don't know how Cisco has implemented the algorithm, so if there is somewhere they use it for seed data, then cool, it matters. Otherwise, it's just a label.Currently Working: CCIE R&S
