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.

Cisco ASA 9.8 CLI Commands. This article is covering most important cisco ASA command of ASA Version 9.8. This article may help network and security guys who deals in day to day troubleshooting call and also help in implementation new setup of cisco ASA firewall in the network. This article intent to NAT, Static NAT, PAT, Object Group, access-list, Inspect ICMP, IKEv2 Policy and SSH access. 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. 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. Not sure what has happened, but this ASA has stopped accepting SSH connections. I did a conf t crypto key zeroize rsa crypto key generate rsa modulus 2048 crypto key generate rsa general-keys modulus 2048 wr mem sh ssh ssh 10.100.0.0 255.255.255.0 inside ssh 0.0.0.0 0.0.0.0 outside ssh timeout 60.

1. 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. 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.
2. Sep 06, 2014 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.

NOTE: Before issuing this command, ensure that your router has a hostname and IP domain name configured (with the hostname and ipdomain-name commands).

You will be unable to complete the cryptokeygeneratersacommand without a hostname and IP domain name. (This situation is not true when you generate only a named key pair.)

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

router (Config) # Line VTY 0 15

router (Config-line)# login local

router (Config-line)# Exit

!!! create local login ID/Pass

router (Config)# username [loginid] password [cisco]

router (Config)# username loginid1 password cisco1

2. router (Config)# ip domain-name example.com

router (Config)# crypto key generate rsa

how many bits in the modulus [512] :1024

router (Config)# ip ssh version2

router (Config)# CTRL Z

Cisco Ssh Rsa Key

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.

The API key will be available in the Credentials section of the API Manager console. There will be a 32 character 'Key' and a 16 character 'Secret'. Recon-ng uses the 'Key' only.FullContact API Key (fullcontactapi) - Create a FullContact account.Google API Key (googleapi) - Create an API Project. Check the 'I agree to comply with the Flickr API Terms of Use.' Get bing search api key.

Modulus Length

When you generate RSA keys, you will be prompted to enter a modulus length. The longer the modulus, the stronger the security. However, a longer modules take longer to generate (see the table below for sample times) and takes longer to use.

The size of Key Modulus range from 360 to 2048. Choosing modulus greater than 512 will take longer time.

Cisco Asa Generate Ssh Key Id

Cisco IOS software does not support a modulus greater than 4096 bits. A length of less than 512 bits is normally not recommended. In certain situations, the shorter modulus may not function properly with IKE, so we recommend using a minimum modulus of 2048 bits.
