Cisco ASA 5505 SSL/HTTPS/ASDM Won't work, Cipher fail

Does my device not support enough encryption to get ASDM/SSL/HTTP working?

First time I've ever seen this...:

%ASA-7-609001: Built local-host identity:192.168.1.1

Do you have "ssl encryption" command on the ASA that sets ciphers that are not matched with the client proposed ciphers?

Can you check using the ssl command?

It responds with :

XXX algorithms require a VPN-3DES-AES activation key.

I've tried like.. 8 of the ones it says my client is proposing.

I shouldn't need a special license to get ASDM working out of the box..

Hmm, do you have a 3DES license on your ASA, or DES? "sh ver" should show you that.

If you have DES it will not do the algorithms for SSL encryption etc.

"This platform has a base license"

So this means that I can't even run ASDM with a base license?

Hi,

It is better you get a 3DES license for your ASA.

Otherwise, one way to get it working would be to change the cipher suites being sent by the client's browser. I am not really sure of how to do that but i am pretty sure google will give you good results.

Let me now how it goes!

Cheers,

Hi,

You tried with different browsers and ssl settings?

Regards.

Great Answer Panagioti, it

Great Answer Panagioti, it worked for me.. the answer was in front of our eyes!

 

%ASA-6-725001: Starting SSL handshake with client inside:xx.xx.xx.xx/59308 for TLS session.
%ASA-7-725010: Device supports the following 3 cipher(s).
%ASA-7-725011: Cipher[1] : AES256-SHA

Thank you for pointing this!

It was helpful, thanks!

It was helpful, thanks!

I had the same problem which I was fighting with last couple days. I had to format and erase my flash during flash replacement, and ASA lost  activation code and all ciphers. After reading your post I realized what is wrong, restored the activation key and applied ciphers to SSL.

Thanks again!

I found this post, but didn't see the answer. I did find the answer elsewhere and wanted to update this post in case someone else has this issue. I had to enable a cipher that was compatible with my browser using the below command on the ASA.

ssl encryption aes256-sha1

Hope this helps someone find the answer quicker.
