You can access Cisco ASA appliance using Command Line Interface (CLI) using either Telnet or SSH and for web-based graphical management using HTTPS (ASDM) management. Telnet uses TCP port 23 and is not secure. 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.
Configure SSH Access in Cisco ASA
Step 1: Configure Enable password. (Optional)
Feb 05, 2014 tengo un problema al querer configurar un tunnel con PKI Yo genero una llave de 1024 exportable para una VPN crypto key generate rsa exportable modulus 10 66020 The Cisco Learning Network. Crypto key generate rsa modulus 1024 on cisco 1800 series to create a Trustpoints. Gus Feb 5, 2014 3:05 PM (en respuesta a Gustavo).
Step 2: Create a username with password.
Step 3: Configure this local username to authenticate with SSH.
Step 4: Create RSA key pair.
Step 5: Now specify only particular hosts or network to connect to the device using SSH.
You can now access the device using SSH from 192.168.1.0 and 172.16.1.0 network.
In this way you can configure remote SSH access in Cisco ASA appliance.

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 SSH1 Setup Local VTY line User ID and password

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 Crypto Key Generate Rsa
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. https://traxpotent269.weebly.com/win-xp-sp3-cd-key-generator.html.
