A digital certificate or identity certificate is an electronic document which uses a digital signature to bind a public key with an identity, information such as the name of a person or an organization, their address, and so forth. The certificate can be used to verify that a public key belongs to an individual.
Oct 16, 2019 Reasons to Store Multiple RSA Keys on a Router. Configuring multiple RSA key pairs allows the Cisco IOS software to maintain a different key pair for each CA with which it is dealing or the software can maintain multiple key pairs and certificates with the same CA. Aug 22, 2013 myswitch(config)# crypto key generate rsa The name for the keys will be: myswitch.thegeekstuff.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. Jul 21, 2017 Peer public RSA key modulus values up to 4096 bits are automatically supported. The largest private RSA key modulus is 4096 bits. Therefore, the largest RSA private key a router may generate or import is 4096 bits. However, RFC 2409 restricts the private key size to 2048 bits or less for RSA.
In a typical public key infrastructure (PKI) scheme, the signature will be of a certificate authority (CA). However, there are situations where it is not possible use a CA, so the only solutions is to use a self-signed certificate, an identity certificate that is signed by the same entity whose identity it certifies.
Router1(config)#crypto key generate rsa The name for the keys will be: Router1.oreilly.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. How many bits in the modulus 512: 1024 Generating RSA keys. Jan 21, 2018 This section contains the following tasks that can be used for exporting and importing RSA keys. Whether you are using PKCS12 files or PEM files, exportable RSA keys allow you to use existing RSA keys on Cisco IOS routers instead of having to generate new RSA keys if the main router were to fail. Exporting and Importing RSA Keys in PKCS12 Files. How I create RSA key and enable SSH access in Cisco VG202, in a Cisco router I use the next commands(but in a VG not exists): conf t. Crypto key generate rsa modulus 1024 ip domain-name domain-name ip ssh version 2 ip ssh time-out 120 ip ssh authentication-retries 3 line vty 0 4 transport input telnet ssh end.
The standard used by Cisco is X.509, an ITU-T standard for a public key infrastructure (PKI) and Privilege Management Infrastructure (PMI). X.509 specifies, amongst other things, standard formats for public key certificates, certificate revocation lists, attribute certificates, and a certification path validation algorithm.
The most common use of certificates is for HTTPS-based web sites. A web browser validates that an SSL web server is authentic, so that the user can feel secure that his/her interaction with the web site has no eavesdroppers and that the web site is who it claims to be. Other uses are VPN lan2lan, GetVPN and so on.
There are two different approaches to create a self-signed certificate: automatic or manual.
To automatically create an rsa key pairs and a certificate, enable the https server:
Where is the certificate?
Remember: Save the configuration to save the certificate!
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:
Create a local PKI:
Remembers: The “subject-name” is the name of the entity whose public key the certificate identifies. For instance, “O” identify the “Organization” and “CN” the Common name
Obtain the certificate from the local certificate authority:
Remember: You must save the configuration to save the certificate!
To see more information about the certificates and the rsa keys are, you can use these commands:
- show crypto pki certificates
- show crypto pki trustpoints
- show crypto key mypubkey rsa
