To access your instances using SSH, generate an SSH key pair, associate the public key with your instances, and use the private key to log in to the instances using SSH.

1. Apr 19, 2011  Cisco Switching/Routing:: Cat6500 - Crypto Key Generate RSA Command Missing Feb 10, 2013. I recently rebuilt the configuration of our Cat6500 multilayer device for use as a user stack. The device is funtioning as it should be, but I am unable to set.
2. May 29, 2018  I could use a second set of eyes to make sure I'm not missing anything. There are no ACL's blocking the traffic. The aaa command is looking for some credentials on the local switch. The command I used to generate the RSA is: crypto key generate rsa modulus 2048 (which uses the general-keys) option by default.

Sep 08, 2016 Use the crypto ca enroll command to request certificates from the CA for the Rivest, Shamir, and Adelman (RSA) key pairs for the router defined by the rsakeypair command in trustpoint configuration mode. If no rsakeypair command is configured for the current trustpoint, the default RSA key pair is used for enrollment. Sep 08, 2016 Use the crypto key generate rsa command to generate RSA key pairs for your router. RSA 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 are warned and prompted to replace the existing keys with new keys.

Keep your SSH keys secure. Lay down policies to ensure that the keys aren’t lost or compromised when employees leave the organization or move to other departments. If you lose your private key, then you can’t access your instances. For business continuity, ensure that the SSH keys of at least two IT system administrators are added to your instances.

Generating an SSH Key Pair on UNIX and UNIX-Like Systems

Use the following procedure to generate an SSH key pair on UNIX and UNIX-like systems:

1. Run the ssh-keygen command.

   You can use the -t option to specify the type of key to create.

   For example, to create an RSA key, run:

   You can use the -t option to specify the length (bit size) of the key, as shown in the following example:

2. The command prompts you to enter the path to the file in which you want to save the key.

   A default path and file name are suggested in parentheses. For example: /home/user_name/.ssh/id_rsa. To accept the default path and file name, press Enter. Otherwise, enter the required path and file name, and then press Enter.

3. The command prompts you to enter a passphrase.

   The passphrase is not mandatory if you want to log in to an instance created using an Oracle-provided image. However, it is recommended that you specify a passphrase to protect your private key against unauthorized use.

   Note:

   With some images provided on Oracle Marketplace, the use of a passphrase might be mandatory.

4. When prompted, enter the passphrase again to confirm it.

The command generates an SSH key pair consisting of a public key and a private key, and saves them in the specified path. The file name of the public key is created automatically by appending .pub to the name of the private key file. For example, if the file name of the SSH private key is id_rsa, the file name of the public key would be id_rsa.pub.

Make a note of the path and file names of the private and public keys. When you create an instance, you must specify the SSH public key value. When you log in to an instance, you must provide the path to the corresponding SSH private key and you must enter the passphrase when prompted.

Generating an SSH Key Pair on Windows

You can generate an SSH key pair on a Microsoft Windows machine by using an application such as PuTTY. See the tutorial, Creating SSH Keys for Use with Oracle Cloud Services.

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.

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

https://mapclever594.weebly.com/blog/life-is-feudal-download-mac. 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.)

Crypto Key Generate Rsa Command Missing Number

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

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.

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.

Generate Rsa Key Pair

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.
