I have issued the command crypto key generate rsa general-keys modulus 2048. What command can be used to verify they key is 2048? Find A Community. Buy or Renew. First, you must create the keys on both devices. We recommend using at least 1024-bit keys in production networks: Router1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router1(config)#crypto key generate rsa The name for the keys will be: Router1.oreilly.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys.

Dec 28, 2009  Do not use anonymous RSA keys (named after the FQDN of the switch). This problem is not seen when using labeled RSA keys: crypto key generate rsa general-keys label (label) mod (modulus) exportable Further Problem Description: The fix for CSCtc41114 was integrated into SXH but did not yet make it into SXI: - builds up to SXI3 are affected. Crypto key generate rsa. cryptokeygeneratersa,page2 Cisco IOS Security Command Reference: Commands A to C, Cisco IOS XE Release 3SE (Catalyst 3850 Switches). Step 4: Erase existing key pairs on the router. R1(config)# crypto key zeroize rsa Note: If no keys exist, you might receive this message:% No Signature RSA Keys found in configuration. Step 5: Generate the RSA encryption key pair for the router. The router uses the RSA key pair for authentication and encryption of transmitted SSH data.

I am looking for something that says the rsa key is 2048. Your output indicates 1024 bits. If my rsa key is set to 2048 what show command(s) indicate this? 0 Helpful Reply. Solved: I have switch 3548-XL with version 12.0(5.3)WC. When attempting to run crypto key genearte rsa, it doesn't work. IP200#conf t Enter configuration commands, one per line.

How do I generate ssh RSA keys under Linux operating systems?
You need to use the ssh-keygen command as follows to generate RSA keys (open terminal and type the following command):
ssh-keygen -t rsa
OR
ssh-keygen
Sample outputs:

The -t type option specifies the type of key to create. The possible values “rsa” or “dsa” for protocol version 2. The $HOME/.ssh stores the following two files:

• $HOME/.ssh/id_rsa – Your private RSA key
• $HOME/.ssh/id_rsa.pub – Your public RSA key

Please do not share keys file with anyone else. You can upload keys to remote server as follows:
ssh-copy-id userName@server2.nixcraft.net.in
Finally, you can login to remote server as follows:
ssh userName@server2.nixcraft.net.in
scp file.txt userName@server2.nixcraft.net.in:~/data2/
