(Optional) Specifies that the RSA public key generated will be a signature special usage key. (Optional) Specifies that two RSA special-usage key pairs, one encryption pair and one signature pair, will be generated. (Optional) Specifies that a general-purpose key pair will be generated, which is the default. Syntax Description : Optional Strings to embed with SSH Crypto key general-keys In certain situations, the shorter modulus may not function properly with IKE, so we recommend using a minimum modulus of 2048 bits. A length of less than 512 bits is normally not recommended.

RouterД¬isco IOS software does not support a modulus greater than 4096 bits. Choosing modulus greater than 512 will take longer time. The size of Key Modulus range from 360 to 2048. However, a longer modules take longer to generate (see the table below for sample times) and takes longer to use. The longer the modulus, the stronger the security. When you generate RSA keys, you will be prompted to enter a modulus length. This command is not saved in the router configuration however, the RSA keys generated by this command are saved in the private configuration in NVRAM (which is never displayed to the user or backed up to another device) the next time the configuration is written to NVRAM. server.ДЇor example, if a router name is вЂњ,вЂќ the key name is вЂњ.вЂќ The additional key pair is used only by SSH and will have a n ame such as. Secure Shell (SSH) may generate an additional RSA key pair if you generate a key pair on a router having no RSA keys.

Crypto Key Generate Rsa 2048 Here are the steps to Enable SSH and Crypto Key setup : 2 config must requried for SSH 1 Setup Local VTY line User ID and password You will be unable to complete the crypto key generate rsa command without a hostname and IP domain name. NOTE: Before issuing this command, ensure that your router has a hostname and IP domain name configured (with the hostname and ip domain-name commands). If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys. keys are generated in pairsвЂ“one public RSA key and one private RSA key. Use this command to generate RSA key pairs for your Cisco device (such as a router). Great info, shows up first with a google search. 13 Comments Posted by Aaron Paxson on March 4, 2008. Configure ACL to allow a specific IP address or range(s).ДЄccessing Cisco ASA using SSH. The authentication method can be local, RADIUS, or TACACS+. You must have at least one user account locally. While itвЂ™s a good idea to have enable password configured, it is optional for SSH. If there is, then you can tell the ssh process to use this key with ip ssh rsa keypair-name xxx.If the first command doesn't show anything useful then I'd say you can go ahead and generate a new key. Run show crypto key mypubkey rsa to see if you do, in fact, have a key fully generated and registered under a non-default name.
