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.
Cisco Pix 515 Software Have RegistrationI bought a DLL plug-in to make my home-brewed software have registration functionality.
![]() 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, its 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 lets get into this topic. Just a couple of days ago, I was given 3 Cisco PIX-515E firewall with Unrestricted (UR) License. Cisco Pix 515 Free Gift FromTo 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 NATPAT tasks. Cisco Pix 515 Serial Number And ActivationI 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. 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: ActiveActive VPN-DES: Enabled VPN-3DES-AES: Enabled Cut-through Proxy: Enabled Guards: Enabled URL Filtering: Enabled Security Contexts: 2 GTPGPRS: 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. A 15 78 78 15 3A 30 78153A30 Refer to the original discussion, we need to put inverted value of the license type mark (AESDESUR 0x00000039 ) to the beginning of the SN we have just converted. You need to remember that the command will be slightly different: qw(md5hex); print md5hex(pack(H, 390000006C394E30 )) 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 Youll get the same result with our victims answer: 0x4b7c1873 0x54ce958f 0x7b74b95e 0x569def49 Not that bad WordPress Permalinks on LEMP Raspberry Pi 2 Has Arrived Leave a Reply Cancel You must be logged in to post a comment.
