CTF Swiss Army Knife

An all-in-one Capture The Flag Challenges solving tool written in Python that combines various utilities commonly needed in CTF challenges. This tool provides a modern, user-friendly GUI interface for various CTF-related tasks on a windows environment.

Features

Cryptography

Decrypt various commonly used and advanced cypher techniques such as Caesar cipher, Vigenère cipher (along with a brute force option to get key), ROT13, Atbash, AES encryption/decryption (ECB and CBC modes), DES encryption/decryption, Triple DES support, XOR operations.

Also supports various Encoding/Decoding operations such as Base16/32/58/64/85/91 conversions, Hex encoding/decoding, Binary encoding/decoding, Decimal encoding/decoding & ASCII Manipulation Format (AMF).

Includes a Smart Detection technique for Automatic format detection and Deep analysis for encoded content. Supports Flag pattern recognition & Multiple encoding layer detection

Steganography

Supports Image Steganography techniques such as LSB (Least Significant Bit) analysis, Data extraction from images and Image format analysis.

Supports Image Audio techniques such as Spectrogram analysis and generation using matplotlib, Image to audio spectrogram conversion, Audio file analysis and Data extraction from audio

Forensics

Supports File Analysis features such as Metadata extraction, File format detection, Magic number analysis, Compression/Zip detection.

Supports External Tools if you have them installed on your device. Tools such as Steghide, Binwalk, Stegsolve, Zsteg, ExifTool, are required to be installed externally to the SYSTEM PATH for the program to detect and use them.

Format Conversion

Includes a Universal Converter for Text format conversion, Multiple input/output format support, Real-time format analysis, Smart format detection

Supported Formats: Text, Hexadecimal, Decimal, Binary, Octal, Base64, Base32, Base16, Base85

Hex Dump Analysis

Supports hex dumb analysis, editing and saving edited files for supported files formats. Also has support to automatically suggest fix for common headers using hex dump of corrupt files for various formats.

Hash Cracking

Supports hash detection and hash cracking based on brute force, dictionary, common passwords and rainbow tables.

Auto Tab

Includes a one click solution auto tab to automatically find a general or user specified text/string format within the input text/file automatically using various techniques at once and return the string if found. The auto tab may not be able to find flags/strings requiring multiple steps or advanced tools.
