Dear Friend
I am have unabled the cisco SDM on my pc, and able to get the http for my router 1841:
I have done below configuraiton in my R1841
1.Generate Encryption key for (used in ssh and https)
conf t
ip domain-name lab.com
!
!
2.Turn on the Https
conf t
ip http server
3.create a privilege level 15 account
conf t
username abhi privilege 15 secret nagar
4. configure your vty and https access ports for previlege 15 and to use the local user database
conf t
ip http authentication local
line vty 0 4
login local
5. install Java on your pc and access the router using a web browser and SDM
But still I am not able to launch the SDM.
Below things I could not able to perform, on R1841, Version 12.4(1c)
crypto key generate rsa general-keys
ip http secure-server
Can you please help me why I am not able to get the above commands, and does my SDM not work due to this or anything else need to be done?

The reason why you can not generate the RSA keys and perform any action that involves encryption is that the IOS of your 1841 does not support encryption. Here is the image file that it is running
System image file is "flash:c1841-ipbase-mz.124-1c.bin"
and this image does not support encryption. If it did support encryption then the image name would include k9 in the file name.

If the router is covered by an active maintenance program so that you can download new code then upgrading the IOS is certainly possible. And the code that you are running 12.4(1c) is actually quite old.
There are two factors to consider when we look at what code is running and what code you might want to change to. The obvious factor is the version of code which is indicated in the numeric value (12.4(1c) or the recent 12.4(24)). The other factor is what is frequently referred to as Feature Set or in recent code may be called the licensing level. And this is the one that controls whether encryption is supported or not. You could upgrade to the new 12.4(24) and if you still use the IP Base without encryption then you still would not be able to generate RSA keys etc. And if you change to a feature set that does support encryption then you could generate RSA keys whether you were still at 12.4(1c) or at the new 12.4(24).
