On every purchase of ASA firewall, Cisco ships product authorization key known as PAK in printed format along with delivery. The steps remain same irrespective of ASA license feature.
- So I went to eBay last night in search for a 10-50 user license key. I find a 10-UL user key for $125.00 and purchased it. Seller had good reviews etc. During our email exchange, he asked for the SN of my ASA5505 so I gave it to him. Next he sends me an email with the license key but he says that, for free, he gave me security plus.

- The pre-shared-key is now displayed in plain text. This applies to all versions of Cisco ASA including 5505 and 5510. Now that you know how to display a Cisco ASA pre-shared-key. Cisco Asa Key Generator. Starsat 2200 hd wifi sport. Feb 18, 2010 - How to recover your Cisco ASA license after a.
1.Login to Cisco registration portal – http://www.cisco.com/go/license and enter PAK key and ASA serial number, then you will get the license key by registered email immediately.
AnyConnect for Cisco VPN Phone: Enabled perpetual. Advanced Endpoint Assessment: Enabled perpetual. UC Phone Proxy Sessions: 2 perpetual. Total UC Proxy Sessions: 2 perpetual. Botnet Traffic Filter: Enabled perpetual. Intercompany Media Engine: Disabled perpetual. This platform has an ASA 5505 Security Plus license.
Caution: When you enter the key in ASA you will need to reboot. Also always save the output of “show version” to keep it in your records prior to entering new key upgrade.
2.Enter the license key in ASA and upgrade software license, in this case, we upgrade sec plus.
(config)# activation-key <license>
(config)# write memory
(config)# reload
3.After reboot, verify that new license key is accepted
(config)# show activation-key

As an engineer myself, I am always curious about how the things work. I could even remember when I was in high school, I used my pocket money to buy a book titled Applied Cryptography, of course it is a Chinese version. I was amazed by the encryption algorithm, such as MD5, RSA, SHA, etc. I bought a DLL plug-in to make my home-brewed software have registration functionality. (I should have studied IT security, shouldn’t I?)
Time flies, I choose Mechanical Engineering to be my major in University but it did not change my ambitious as well as my field of interest. I remembered the first few days I bought my Arduino kit, I was trying to dig some interesting protocols for encryptions using that microcontroller. Well, it’s a 8-bit MCU so it is not likely possible to implement strong algorithms like RSA and MD5. I found someone making CRC32 and SHA on that platform but it will take a few seconds to get the work done.
Anyway, I am talking too much about the past so let’s get into this topic.
Just a couple of days ago, I was given 3 Cisco PIX-515E firewall with Unrestricted (UR) License. To be honest, I had really no idea with these firewalls and only know about the Cisco ISR series during that time (Yes, I am studying CCNA at the moment and the PIX firewalls are unwanted free gift from one eBay seller.). Soon after, I found the ASA could be a very useful equipment in networking as they are capable of doing not only the fire fighters job, but also be NAT/PAT tasks.
I watched a youtube video and the instructor tried to use valid Serial Number and Activation Keys to activate the “virtual” PIX-515E in GNS3 software. As a result, I was getting much more interested in the activation key algorithms than ever! I had a brief look on the eBay.com.au, there were couple of sellers who were selling UR Licenses at a premium price and it looked like a must have (handy) bundle for CCNP students.
I was accidentally got an article on one Russia website, and one of the ‘hacker’ revealed the software algorithm for the UR license key so I would like to write an English version to make it clearer.
Please ignore above paragraphs if you are above the CCNA level :-).
I need to grab a working SN and Key to verify the process is all working. So I grabbed a victim on eBay:
Licensed features for this platform:
Maximum Physical Interfaces : 6
Maximum VLANs : 25
Inside Hosts : Unlimited
Failover : Active/Active
VPN-DES : Enabled
VPN-3DES-AES : Enabled
Cut-through Proxy : Enabled
Guards : Enabled
URL Filtering : Enabled
Security Contexts : 2
GTP/GPRS : Disabled
VPN Peers : Unlimited
This platform has an Unrestricted (UR) license.
Serial Number: 809112952
Running Activation Key: 0x4b7c1873 0x54ce958f 0x7b74b95e 0x569def49
Firstly, we need to convert the Serial Number from DEC to HEX. Just use the calculator to conduct the conversion.
DEC(809112952)=HEX(0x 30 3A 15 78)
Secondly, we need to make the inversion of the digits.
30 3A 15 78 => 78 15 3A 30 => 78153A30
Cisco Asa 5520 Activation Key Generator
Refer to the original discussion, we need to put inverted value of the license type mark (AES+DES+UR = 0x00000039) to the beginning of the SN we have just converted.
“39000000” + “78153A30” = 3900000078153A30
Then we needs a MD5 conversion using a perl syntax:
If you are running or having a Mac or Linux based O/S, just using the following command:
Cisco Asa License Key Generator Download
perl -e ‘use Digest::MD5 qw(md5_hex); print md5_hex(pack(“H*”, “390000006C394E30“))’
If you cannot have access to the Linux or Unix based PC, you can use online compiler, such as: http://www.tutorialspoint.com/execute_perl_online.php. You need to remember that the command will be slightly different:
qw(md5_hex); print md5_hex(pack(“H*”, “390000006C394E30“))
Cisco Asa License Key
You will get the following result:
73187c4b 8f95ce54 5eb9747b 49ef9d56
Last step, we need to separate the result to 4 groups (shown above), and make the inversion AGAIN to get the final result! You’ll get the same result with our victim’s answer:
0x4b7c1873 0x54ce958f 0x7b74b95e 0x569def49
Not that bad!
