Cryptographic Recommendation Summary

This post contains recommendation summaries for password security and cryptographic topics including password complexity & storage, hash functions, symmetric & asymmetric encryption, MACs, ...

Sequential Payload Generator

This tool generates a list of sequential payloads starting and ending at the specified numbers. These values can be arbitrarily large and outputted as integers, HEX values, or base64 encoded string...

XOR Encryption Cracker

This is a tool for breaking the encryption of messages that have been XOR encrypted using a repeated key. This method uses statistics (letter frequencies and use of common words, bigrams, and trigr...

Cracking WPA2-PSK with Hashcat

This post will cover how to crack Wi-Fi passwords (with Hashcat) from captured handshakes using a tool like airmon-ng. Install hcxtools Extract Hashes Crack with Hashcat Install hcxtools ...

Getting Started with airmon-ng

This post will show how to get started using aircrack-ng to discover wi-fi networks, capture handshakes, deauth clients, and crack passwords. Setup airmon-ng Install aircrack-ng Suit...

Cryptography - Byte by Byte ECB Decryption

In this post we’ll cover how to attack an oracle function that encrypts user supplied data concatenated with an unknown string under ECB mode while using a constant but unknown key. This post will...

Cryptography - Breaking Repeating Key XOR Encryption

In this post we’ll cover how to decrypt messages that have been XOR encrypted using a repeated key, such as 84 d2 7a 09. The method we’ll be using to break the encryption uses statistics (letter fr...
