Cisco ASA 5510 Adaptive Security Appliance that runs software version 8.02 and ASDM version 6.02... ASA-1# configure terminal ASA-1config#crypto key generate rsa label modulus 1024 !--- Generates 1024 bit RSA key pair. quot;labelquot; defines the name of the Key Pair. INFO: The name for the keys will be: my.CA. Use this command to generate RSA key pairs for your Cisco device such as a router. RSA keys are generated in pairs--one public RSA key and one private.

'crypto key generate rsa' necessary for SSH? - Cisco Community.

Note that this does not count the encoding that says quot;this is an RSA public keyquot;; that takes up an additional 24 bytes including overhead. That's generally included in public keys, but apparently you're not counting that part; that would bring the length past the 540 hex characters you see.

Why is a 2048-bit public RSA key represented by 540.

The device is funtioning as it should be, but I am unable to set SSH using the 'crypto key generate rsa' command. The crytop command isn't avaiable at all, which suggests a firmware issue. I have configured a hostname and Ip domain-name and the image is the only one available. The show version output is listed below. show ver. Creating the CSR. 1. Go to ASDM -gt; Configuration-Remote -gt; Access VPN -gt; Certificate Management -gt; Identity certificates -gt; Add. 2. Create a new keypair or use the default keys. 3.Fill the certificates values. 4.Fill the FQDN value on the advanced options.

Creating a CSR, Authenticating a CA and Enrolling... - Cisco.

From the navigation pane, click Device Administration gt; Device. Enter a Host Name and Domain Name for the ASA. Click Apply. When prompted, click Save gt; Yes. Configure the ASA with the correct date, time, and time zone. This is important for certificate generation of the device. Use an NTP server, if possible. Below is an excerpt taken from a shell session some details may have been altered: userlocalhost: ssh-keygen Generating public/private rsa key pair. Enter file in which to save the key /user/: Enter passphrase empty for no passphrase: Enter same passphrase again: Your identification has been saved in /user/.

Configuring the Local Database for AAA - Cisco.

The ASA allows SSH connections to the ASA for management purposes. The ASA allows a maximum of 5 concurrent SSH connections per context, if available, with a maximum of 100 connections divided between all contexts. hostname lt;device_hostnamegt; domain-name lt;domain-namegt; crypto key generate rsa modulus 2048 The default key-pair type is general key. The router does this by default. In order to do this, when you define the trustpoint under the crypto map add the chain keyword as shown here: crypto map outside-map 1 set trustpoint ios-ca chain. If this is not done, then the the tunnel only gets negotiated as long as the ASA is the responder. Enable SSH. The ASA allows SSH connections to the ASA for management purposes. The ASA allows a maximum of 5 concurrent SSH connections per context, if available, with a maximum of 100 connections divided between all contexts. hostname lt;device_hostnamegt; domain-name lt;domain-namegt; crypto key generate rsa modulus.

CLI 1:Cisco ASA 9.12 CLI .

This section contains links to the sections that contain instruction steps that show how to integrate Cisco ASA with RSA SecurID Access using all of the integration types and also how to apply them to each supported use case. First configure the integration type e.g. RADIUS then configure the use case e.g. AnyConnect .

VIP. Options. 08-16-2012 02:26 PM. you need a public/private keypair: asa config# crypto key generate rsa general-keys modulus 2048. a username: asa config# username testuser password testpass. and the system should know where your useraccounts are: asa config# aaa authentication ssh console LOCAL. 2 For Type of key to generate, select SSH-2 RSA. 3 Click the Generate button. 4 Move your mouse in the area below the progress bar. When the progress bar is full, PuTTYgen generates your key pair. 5 Type a passphrase in the Key passphrase field. Type the same passphrase in the Confirm passphrase field. The ASA tries to use keys in the following order if they exist: EdDSA, ECDSA, and then RSA. If you explicitly configure the ASA to use the RSA key with the ssh key-exchange hostkey rsa command, you must generate a key that is 2048 bits or higher. For upgrade compatibility, the ASA will use smaller RSA host keys only when the default.

In addition, if the PIX has undergone a write erase!--- or has been replaced, then cutting and pasting !--- the old configuration does not generate the key. !--- You must re-enter the ca gen rsa key command. !--- If there is a secondary PIX in a failover pair, a write standby!--- command does not copy the key from the primary to the secondary.

Cisco Guide to Harden Cisco IOS Devices - Cisco.

A bit late for an answer, but as the other answers are purely heuristic, here some background about why it takes so much longer: The slowest part of an RSA key generation is usually the Fermat test, which has to be run for each prime candidate x and consists of checking if 2x-1 = 1 modulo x using 2 can be made faster than using other. The ASA supports the SSH remote shell functionality provided in SSH Versions 1 and 2 and supports DES and 3DES ciphers. XML management over SSL and SSH is not supported. 8.4 and later The SSH default username is no longer supported. You can no longer connect to the ASA using SSH with the pix or asa username and the.

The vulnerability affects Cisco products running vulnerable Cisco ASA 9.16.1 and later or Cisco FTD 7.0.0 and later software which perform hardware-based cryptographic functions: ASA 5506-X.

The information in this document is based on Cisco CUCM 11.0, where Elliptic Curve Digital Signature Algorithm ECDSA certificates are only supported for CallManager CallManager-ECDSA. Note: CUCM 11.5 and later supports tomcat-ECDSA certificates as well. The information in this document was created from the devices in a.
