- Research direction
- Examine existing operation implementations in the CyberChef codebase, such as 'Gunzip' or 'Inflate', to understand the pattern for adding a new operation. The FlateDecode operation can be implemented using a library like pako (zlib port) or by directly decompressing raw deflate data. The issue suggests adding a 'FlateDecode' operation; research the CyberChef API for registering operations (likely in src/core/operations/) and refer to the issue #274 for further context. Ensure the operation is added to the appropriate category and includes necessary type definitions.
