Ssh is secure protocol used to manage remote systems like Linux, BSD, UNIX, network devices event windows operating systems. The traffic between systems are encrypted. Ssh uses asymmetric keys in order to encrypt and made traffic invisible to the others those resides between systems in the network. The encryption power comes from key bit size or length. In this tutorial we will look how to create 4096 bit keys.

In this example we will generate very secure key. This key size will be 4096 bit. 4096 bit keys are a lot more secure than 2048 or 1024 bit keys. If we are not transferring big data we can use 4096 bit keys without a performance problem. We will use -b option in order to specify bit size to the ssh-keygen .

What Is Crypto Key Generate Rsa Modulus 1024

R1(config)# crypto key generate rsa The name for the keys will be: R1.NETWORKLESSONS.LOCAL Choose the size of the key modulus in the range of 360 to 4096 for your General Purpose Keys. When you use the crypto key generate rsa command, it will ask you how many bits you want to use for the key size. How much should you pick? Apr 05, 2020  BlueRtr(config)#crypto key generate rsa The name for the keys will be: BlueRtr.joelrivera.com.local Choose the size of the key modulus in the range of 360 to 4096 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. /github-ubuntu-generate-ssh-key.html. May 29, 2016 The most effective and fastest way is to use command line tools: codeopenssl genrsa -out mykey.pem 4096 openssl rsa -in mykey.pem -pubout mykey.pub /codeIt’ll generate RSA key pair in code mykey.pem/code and code mykey.pub/code.

RSA is very old and popular asymmetric encryption algorithm. It is used most of the systems by default. There are some alternatives to RSA like DSA . We can not generate 4096 bit DSA keys because it algorithm do not supports.

The default key size for the ssh-keygen is 2048 bit. We can also specify explicitly the size of the key like below.

The less secure key size is 1024 bit. We do not recommend usage of this size of keys but in some situations like old systems we may need this size of keys. Here how we can generate 1024 bit key with ssh-keygen .
