Please create RSA keys (of at least 768 bits size) to enable SSH v2.
Kim(R1)(config)#crypto key generate rsa
The name for the keys will be: Kim(R1).Router
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
