I built a Python deobfuscator using AST transformers - Noctyra

Hey everyone! I just released Noctyra , a tool i built to handle Python deobfuscation using AST transformers. It's been a fun side project and I figured it was time to share it. Why AST and not regex? Most quick deobfuscation scripts you'll find online rely on regex replacements or target specific obfuscators. That works for simple cases, but fall apart easily when the obfuscation is layered or unknown. Noctyra works directly on the Abstract Syntax Tree (AST). Instead of treating the code as text, it: Parses the source into an AST Applies a sequence of transformers on the nodes Unparses the result back into clean, readable and formated Python This means it can handle things like constant folding, resolving encoded strings, junk code without ever caring about formatting or unreadable code. How the pipeline works The pipeline runs transformers in iterations until the AST stops changing between passes. This is what makes it effective against layered obfuscation. For example, something lik
