Cisco asa activation key generator serial#Unlike product authorization key (PAK) licenses, smart licenses are not tied to a specific serial number. With the realease of 9.3 for ASA’s Cisco introduced Smart Licensing where it lets you purchase and manage a pool of licenses centrally. If you cannot have access to the Linux or Unix based PC, you can use online compiler, such as. If you are running or having a Mac or Linux based O/S, just using the following command: Then we needs a MD5 conversion using a perl syntax: 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. Secondly, we need to make the inversion of the digits. Just use the calculator to conduct the conversion. Cisco asa activation key generator serial number#Running Activation Key: 0x4b7c1873 0x54ce958f 0x7b74b95e 0x569def49įirstly, we need to convert the Serial Number from DEC to HEX. This platform has an Unrestricted (UR) license. I need to grab a working SN and Key to verify the process is all working. =Please ignore above paragraphs if you are above the CCNA level :-).= Cisco asa activation key generator license key#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. As a result, I was getting much more interested in the activation key algorithms than ever! I had a brief look on the, 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 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. 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. 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.). Just a couple of days ago, I was given 3 Cisco PIX-515E firewall with Unrestricted (UR) License. I found someone making CRC32 and SHA on that platform but it will take a few seconds to get the work done.Īnyway, I am talking too much about the past so let’s get into this topic. Well, it’s a 8-bit MCU so it is not likely possible to implement strong algorithms like RSA and MD5. I remembered the first few days I bought my Arduino kit, I was trying to dig some interesting protocols for encryptions using that microcontroller. 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 should have studied IT security, shouldn’t I?) I bought a DLL plug-in to make my home-brewed software have registration functionality. I was amazed by the encryption algorithm, such as MD5, RSA, SHA, etc. 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. =WARNING: This article is for Academic purposes ONLY and not with intention to make profits or resell.=Īs an engineer myself, I am always curious about how the things work.
