Crypto key generate rsa. cryptokeygeneratersa,page2 Cisco IOS Security Command Reference: Commands A to C, Cisco IOS XE Release 3SE (Catalyst 3850 Switches). Oct 02, 2015  SSH Config and crypto key generate RSA command. Use this command to generate RSA key pairs for your Cisco device (such as a router). Keys are generated in pairs–one public RSA key and one private RSA key. 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. Configure the RSA keys with 1024 for the number of modulus bits. R1(config)# crypto key generate rsa general-keys modulus 1024. Issue the command to force the use of SSH version 2. R1(config)# ip ssh version 2. Configure the vty lines on R1 and R3 to use the local database for login. Remote access to the routers should only be allowed. What exactly does 'crypto key generate rsa' do? When setting up SSH you have to create the rsa key, what does it actually do? Such that P.Q results in a number that matches the desired RSA Key size (512 bits, 1024 bits, 2048 bits, etc) Calculate P.Q. I'm using Packet Tracer which is helping alot. Study materials are CBT Nuggets.

Aug 25, 2016  Switch (config)# crypto key generate rsa Enables the SSH server for local and remote authentication on the Switch and generates an RSA key pair. Generating an RSA key pair for the Switch automatically enables SSH. We recommend that a minimum modulus size of 1024 bits. When you generate RSA keys, you are prompted to enter a modulus length. Crypto key generate rsa modulus 1024 e. At the privileged EXEC mode prompt, issue the write mem (or copy run start ) command to save the running configuration to the startup configuration and the RSA keys to non-volatile memory.

You can access Cisco ASA appliance using Command Line Interface (CLI) using either Telnet or SSH and for web-based graphical management using HTTPS (ASDM) management. Telnet uses TCP port 23 and is not secure. Secure Shell (SSH) on the other hand uses port 22 and is secure. SSH uses public key cryptography to authenticate remote user. You can configure SSH access in Cisco ASA device using the steps shown here.

Configure SSH Access in Cisco ASA

Step 1: Configure Enable password. (Optional)

Step 2: Create a username with password.

Step 3: Configure this local username to authenticate with SSH.

Step 4: Create RSA key pair.

Step 5: Now specify only particular hosts or network to connect to the device using SSH. Driver easy 5.5.5 key generator.

You can now access the device using SSH from 192.168.1.0 and 172.16.1.0 network.

In this way you can configure remote SSH access in Cisco ASA appliance.
