A PyQt5-based Windows GUI tool that uses inference models to identify the encryption or hashing algorithm behind a given ciphertext and attempts to recover the plaintext. It supports algorithms like AES, DES, 3DES, SM4, MD5, SHA, and SM3, and includes a rooted-Android memory-dump feature for analyzing encrypted parameters in mobile apps.

Use cases

• identify which encryption algorithm produced a ciphertext
• recover plaintext from encrypted request parameters during web reverse engineering
• crack MD5 or SHA hashes of captured parameters
• decrypt AES/DES ciphertext with unknown mode and padding
• analyze encrypted parameters in Android apps via memory dumping
• learn how common encryption algorithms behave in practice

When to choose

• you are reverse-engineering a website or app and need to quickly identify parameter encryption
• you have ciphertext samples and want to guess the algorithm and recover plaintext fast
• you do security research on captured traffic with encrypted fields

When to avoid

• you need a general-purpose cryptography library for production code
• you need Linux or macOS support (currently Windows-only)
• you expect guaranteed decryption without any known plaintext or key hints
