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.
Oct 17, 2019 Dismiss Join GitHub today. GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together. Nov 27, 2012 RSA generate key in C Hi all, as I need to generate RSA key by modulus and exponent. I have used the OPENSSL before, is it any other choice to do these operation? Nov 2012 Posts 1,393. It sounds like you want to implement the RSA key generation yourself. In that case, look up information about the algorithm and try to implement it. Keys can be used for Data Encryption and Digital Signing. They can be generated by OpenSSL which i have talked about in a previous article. OpenSSL – Generate a RSA Key and Keystore Actually, the Java JDK also provides API for creating key pair. Done =) Reference: RSA encryption in Java.
Generate ssh key pair ansible list. EC2 doesn't like when you put a full path for the.pem key file.So, I moved EC2-Kibi-Enterprise-Deployment.pem into /.ssh, added it to the authentication agent with ssh-add using: ssh-add /.ssh/EC2-Kibi-Enterprise-Deployment.pemAnd corrected the key line in my var file to key: EC2-Kibi-Enterprise-Deployment.pemThe same if you use EC2 cli tools, don't specify a full path to the key file. The solution has been found. Ec2-run-instances ami-d1ec01a6 -t t2.medium -region eu-west-1 -key EC2-Kibi-Enterprise-Deployment.pem.
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).
Aug 23, 2012 openssl: RSAgeneratekey, problems i'm working on linux and i have a problem. The RSAgeneratekey generate always the same public key on different running, and on different sources. Here is the command line for RSA key generation: OpenSSL: Documents, genrsa(1) So you could see what's different between your code and how 'openssl' does it. Openssl: RSAgeneratekey, problems The RSAgeneratekey generate always the same public key on different running, and on different sources. How can i generate always different key for each call?
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

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.” |
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
Warning Rsa Rsa_generate_key Is Deprecated Compile In Linux
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.
Warning Rsa Rsa_generate_key Is Deprecated Compile In Microsoft
| 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.
