Router#config t
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]
 
jinyan(config)#ip ssh time-out 60
*?? 1 0:1:7.740:  RSA key size needs to be at least 768 bits for ssh version 2
