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.

The second method requires three steps: create an rsa key pairs, create a self signed trust point and enroll the certificate. Create an RSA keys: Ciscozine(config)#crypto key generate rsa label ciscozine-rsa modulus 2048 The name for the keys will be: ciscozine-rsa% The key modulus size is 2048 bits% Generating 2048 bit RSA keys, keys will be non-exportable.
You will have to generate a private and a public encryption key in order to securely send the order information to FastSpring. There are two ways on how to generate these keys. The easy way or the long way. The easy way is only possible, if your server is supporting openssl functionalities needed for encryption.

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.

Diskgenius 5.2.0 crack key generator reviews. It allows you to resize, extend, split, create, delete, format, hide, copy and erase partition to maximize disk space use.

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.)

Nov 23, 2011 router(config)#crypto key generate rsa usage-keys label router-key The name for the keys will be: router-key Choose the size of the key modulus in the range of 360 to 2048 for your Signature Keys. Choosing a key modulus greater than 512 may take a few minutes. How many bits in the modulus 512: 1024. Lab Catalyst 3550 does not show Crypto Key generate command.

I am trying to run the '(config)#crypto key generate rsa' command with no luck. The switch seems. RSA is an asymmetric encryption algorithm. With a given key pair, data that is encrypted with one key can only be decrypted by the other. This is useful for encrypting data between a large number of parties; only one key pair per person need exist.

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

Note

Secure Shell (SSH) may generate an additional RSA key pair if you generate a key pair on a router having no RSA keys. The additional key pair is used only by SSH and will have a name such as {router_FQDN }.server.

For example, if a router name is “router1.cisco.com,” the key name is “router1.cisco.com.server.”

Each time a key pair is created, Kleopatra generates: a unique 40-character fingerprint What must you do to any certificate imported into Kleopatra before you can use it to decrypt messages? Each time a key pair is created kleopatra generates. Create a personal OpenPGP key pair. OpenPGP key pairs are created locally, and certified by your friends and acquaintances. There is no central certification authority; instead, every individual creates a personal Web Of Trust by certifying other user's key pairs with his own certificate. Each time a key pair is created, Kleopatra generates: No because you must provide your public key to any user wanting to decrypt any message encrypted by you If someone sends you his public key and you import it into Kleopatra, will he be able to decrypt the encrypted messages you send him?

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.

Router	360 bits	512 bits	1024 bits	2048 bits (maximum)
Cisco 2500	11 seconds	20 seconds	4 minutes, 38 seconds	More than 1 hour
Cisco 4700	Less than 1 second	1 second	4 seconds	50 seconds

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.

Syntax Description : Optional Strings to embed with SSH Crypto key

general-keys

(Optional) Specifies that a general-purpose key pair will be generated, which is the default.

usage-keys

(Optional) Specifies that two RSA special-usage key pairs, one encryption pair and one signature pair, will be generated.

signature

(Optional) Specifies that the RSA public key generated will be a signature special usage key.

encryption

(Optional) Specifies that the RSA public key generated will be an encryption special usage key.

labelkey-label

(Optional) Specifies the name that is used for an RSA key pair when they are being exported.If a key label is not specified, the fully qualified domain name (FQDN) of the router is used.

exportable

(Optional) Specifies that the RSA key pair can be exported to another Cisco device, such as a router.

modulusmodulus-size

(Optional) Specifies the IP size of the key modulus.By default, the modulus of a certification authority (CA) key is 1024 bits. The recommended modulus for a CA key is 2048 bits. The range of a CA key modulus is from 350 to 4096 bits.

Note

Effective with Cisco IOS XE Release 2.4 and Cisco IOS Release 15.1(1)T, the maximum key size was expanded to 4096 bits for private key operations. The maximum for private key operations prior to these releases was 2048 bits.

storagedevicename:

(Optional) Specifies the key storage location. The name of the storage device is followed by a colon (:).

redundancy

(Optional) Specifies that the key should be synchronized to the standby CA.

ondevicename:

(Optional) Specifies that the RSA key pair will be created on the specified device, including a Universal Serial Bus (USB) token, local disk, or NVRAM. The name of the device is followed by a colon (:).Keys created on a USB token must be 2048 bits or less.
