MIFARE Classic Tool vs Rethink: DNS + Firewall + VPN
Side-by-side comparison of two open source alternatives
MIFARE Classic Tool
This is a low-level tool for reading, writing and analyzing MIFARE Classic RFID tags. It is designed for users who have at least basic familiarity with the MIFARE Classic technology. It provides several features to interact with (and only with) MIFARE Classic RFID-Tags. Read MIFARE Classic tags Save, edit and share the tag data you read Write to MIFARE Classic tags (block-wise) Clone MIFARE Classic tags (Write dump of a tag to another tag; write 'dump-wise') Key management based on dictionary-attack (Write the keys you know in a file (dictionary). MCT will try to authenticate with these keys against all sectorsand read as much as possible.) Format a tag back to the factory/delivery state Write the manufacturer block of special MIFARE Classic tags Use external NFC readers like ACR 122U Create, edit, save and share key files (dictionaries) Decode & Encode MIFARE Classic Value Blocks Decode & Encode MIFARE Classic Access Conditions Display generic tag information Display the tag data as highlighted hex Display the tag data as 7-Bit US-ASCII Display the MIFARE Classic Access Conditions as a table Display MIFARE Classic Value Blocks as integer Calcualate the BCC Quick UID clone feature Import/export/convert files In-App (offline) help and information It's open source ;) More information can be found at the README. It should work on most NFC-enabled devices but there are exceptions. Have a look at the list of devices which are known to be incompatible to MIFARE Classic.

Rethink: DNS + Firewall + VPN
Say hello to a safer, transparent, and secure Android. VPN: Connects to multiple WireGuard VPNs of your choice. Safe: Reveals network activity of installed apps and lets you disable, uninstall, or firewall them. Secure: First line of defense against spyware, ransomware, and malware that steal personal information and takeover accounts. Protects from DNS manipulation typically employed to censor websites, social media, and messaging apps. Fast: DNS Servers deployed to 300+ locations world-wide to ensure your internet is as fast and highly available as it can be. Open: Open source and free of any trackers. ***Features*** Firewall: Prevent apps from connecting to the Internet. Block spyware, malware, ransomware and more. A firewall blocks any app connecting to the Internet over WiFi or Mobile data. Since most forms of surveillance require the data to be sent the network to a server, firewalling them effectively mitigates the threat (File Managers, Alarm Clock, Calculator are few such examples of apps that do not require any Internet access to function). The firewall feature uses Accessibility Service to detect and firewall background applications. Monitoring: Keep tabs on incoming and outgoing Internet traffic. If enabled, the connectivity logs are collected and analyzed. Automated reports flag previously unknown or suspicious connections, and reveal the extent of attempt to steal data by spyware networks. In our tests, around 60% of the traffic is flagged and reported as being initiated by known spyware. Logs generated are made available in near-real time to the user for their own analysis. WireGuard: Secure outgoing Internet traffic. The app uses fast, modern, light-weight, and secure WireGuard protocol to encrypt outgoing connections to any compatible VPN provider of your choice. Anti-censorship: The app encrypts your internet connection to Domain Name System (DNS) server run by Rethink with presence in our 300+ locations world-wide. DNS servers are the address book of the internet: A DNS server provides the exact addresses you need to visit a website or open an app. Data Monitor: Track per-app and per-connection Mobile or WiFi data usage.
