Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#hostname jinyan

jinyan(config)#ip domain-name jinyan.com

jinyan(config)#crypto key ge

jinyan(config)#crypto key generate rsa

The name for the keys will be: jinyan.jinyan.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]: 512

% Generating 512 bit RSA keys, keys will be non-exportable...[OK]
