Jul 30, 2014 Then of course, we would generate the RSA key: crypto key generate rsa general-keys modulus 2048. OK, this part of the configuration has probably changed the least in light of using the management port. I’d like to highlight that using the following command as a substitute for the one above did not work: ip domain-name vrf mgmtVrf lom.oucs.ox. Solved: Hi, I want to know what it the subsitute of cisco the 'crypto key generate rsa general-keys modulus 2048' in juniper. Regards, Dil. All, question - my understanding was that the ASDM/GUI uses the general public key to generate it's ssl cert - e.g. When browsing to the ASA for ASDM access - customer would like to change the ssl cert from 1024 bits 2048. Any ideas how I. Usage-keys (Optional) Specifies that two RSA special-usage key pairs, one encryption pair and one signature pair, will be generated. I am trying to understand why i would you use over another (SG for this task used usage-keys). (Task: Generate RSA keys on SW1 and 2 using domain name ine.com, for maximum security use key length of 2048 bits). Ciscoasa(config)# crypto key generate rsa?

Introduction

This repo contains the code, templates and playbooks that accompanies the:
Hands-on Guide to Multi-Tiered Firewall Changes with Ansible and Batfish

Installation

Repo

Create VirtualEnv

VIRL topology

To spin up the VIRL topology run the command:

Any issues stop/remove topology from VIRL UWM UI, and remove the id file via rm .virl/*/id.

Repo Layout

Note: The playbooks that use the Batfish modules are named bf_xxxxxx.yml. Excel 2016 activation key generator 2013.

Caveats

• VIRL topology - Cisco ASA requires a new key pair to be created on each boot. Therefore crypto key generate rsa general-keys modulus 2048 noconfirm is added to the configuration. This command however is removed if you perform an 'extract configs' from within VIRL.

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).

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

Crypto Key Generate Rsa General-keys Modulus 1024

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.

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.
