SSH

SSH
Enabling ssh makes managing your network alot more secure. Telnet sends traffic over the network in clear text allowing anyone who has access or gains access to get your username or details.
Configuring ssh is easy using the following step
Step 1: Configure the hostname and your username to login to the router.

note: If you are using tacac or radius, make sure it works with telnet first.
hostname router
aaa new-model
username ops password password
Step 2: Configure a domain name on your router, you can remove this after the keys are generated if you require
ip domain-name composednetworks.com
Step 3: Generate an SSH key to be used with SSH.
crypto key generate rsa general-keys modulus 1024
Step 4: Only allow ssh connections to your router:
line vty 0 4
transport input ssh
Step 5: Verify ssh is working on your router:
pc# ssh <router> -l <username>
debug ip ssh
- To debug SSH.
show ssh
- Displays ssh connections.
show ip ssh
- To verify that ssh is enabled and current ssh configurations.
Disabling SSH
no crypto key generate rsa will not work, you must use:
crypto key zeroize rsa
- This will fully disable ssh, remember to allow telnet first on your vty lines.
Cisco have a very good document on its site:

Show crypto key mypubkey rsa: Shows information about the SSL certificate If you’d like to learn more about on how to configure SSH on a Cisco router I recommend you read through this documentation: Configuring Secure Shell on Routers and Switches Running Cisco IOS. Crypto key generate rsa general-keys label tokenkey1 storage usbtoken0: The following example specifies the redundancy keyword: Router(config)# crypto key generate rsa label MYKEYS redundancy. The name for the keys will be: MYKEYS. Choose the size of the key modulus in the range of 360 to 2048 for your. General Purpose Keys.

Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Use the generateKey() method of the SubtleCrypto interface to generate a new key (for symmetric algorithms) or key pair (for public-key algorithms).

Syntax

Parameters

algorithm is a dictionary object defining the type of key to generate and providing extra algorithm-specific parameters.
- For RSASSA-PKCS1-v1_5,Â RSA-PSS, orÂ RSA-OAEP: pass an RsaHashedKeyGenParams object.
- For ECDSA or ECDH: pass anÂ EcKeyGenParams object.
- For HMAC: pass an HmacKeyGenParams object.
- For AES-CTR, AES-CBC, AES-GCM, or AES-KW: pass an AesKeyGenParams object.
extractable is a Boolean indicating whether it will be possible to exportÂ the key using SubtleCrypto.exportKey() or SubtleCrypto.wrapKey().
keyUsages Â is an Array indicating what can be done with the newly generated key. Possible values for array elements are:
- encrypt: The key may be used to encrypt messages.
- decrypt: The key may be used to decrypt messages.
- sign: The key may be used to sign messages.
- verify: The key may be used to verify signatures.
- deriveKey: The key may be used in deriving a new key.
- deriveBits: The key may be used in deriving bits.
- wrapKey: The key may be used to wrap a key.
- unwrapKey: The key may be used to unwrap a key.

Return value

result is a Promise that fulfills with a CryptoKey (for symmetric algorithms) or a CryptoKeyPair (for public-key algorithms).

Exceptions

The promise is rejected when the following exception is encountered:

SyntaxError: Raised when the result is a CryptoKey of type secret or private but keyUsages is empty.
SyntaxError: Raised when the result is a CryptoKeyPair and its privateKey.usages attribute is empty.
