MIFARE Classic

Here are the steps to follow in order to read your cards. Your goal is to find as many keys as possible. The keys unlock sections of your card for the Flipper to read them - you must have a card. Once you read enough sections, you can use an emulated or cloned card at the original card reader to unlock it (sometimes even without finding all of the keys!).

Reading the card

Steps:

1. Dictionary attack: Try to scan your MIFARE Classic card with NFC -> Read. It will try a dictionary attack of default keys to unlock your card, as well as any keys you may have found through other methods. Do not interrupt the dictionary attack, it may take a while! If it finds 32/32 keys (or 80/80) with 16/16 sectors (or 40/40), congratulations and proceed to "Emulation". If not, continue to step 2.
2. Mfkey32 attack (): If you have only a few keys found or no keys found, you can get mor

Developer experience, libraries, performance… (2021/11)

I'll preface this with three things. 1. I prefer schemes over Common Lisps, and I prefer Racket of the Schemes. 2. There is more to it than the points I raise here. 3. I assume you have no previous experience with Lisp, and don't have a preference for Schemes over Common Lisp. With all that out of the way... I would say Common Lisp/SBCL. Let me explain

1. SBCL Is by far the most common of the CL implementations in 2021. It will be the easiest to find help for, easiest to find videos about, and many major open source CL projects are written using SBCL
2. Download a binary directly from the website http://www.sbcl.org/platform-table.html (even for M1 macs) to get up and running (easy to get started)
3. Great video for setting up Emacs + Slime + Quick Lisp https://www.youtube.com/watch?v=VnWVu8VVDbI

Now as to why Common Lisp over Scheme

ARN Base Pattern :-

arn:<aws_parition>:<aws_service>:[<aws_region>]:<account_id>:<root | resource_type>:/<resource_name>[/<sub_resource_names>...]

i. <aws_partition>
Regex - (aws|aws-us-gov|aws-cn)

ii. <aws_service> - No fixed pattern
iii. <aws_region> - No fixed pattern
Most of the regions occur in combination of 2 letter followed by "-" followed by a combination of direction based word , followed by a "-" and then a digit.
