Overview ¶

hexreplace is a tool to patch binary file with hex string. Usage: hexreplace <file path> <frida new name> Example: hexreplace /Users/xxx/Desktop/frida-ios-dump/FridaGadget.dylib frida Author: suifei@gmail.com Github: https://github.com/suifei/fridare/tree/master/hexreplace Version: 2.2

changelog: - 2.2:

• Added support for ELF and PE file formats
• Added functions for describing architectures: describeMachOArch, describeELFArch, describePEArch
• Modified buildReplacements function to support different executable formats
• Unified file detection and opening logic into detectAndOpenFile function
• Refactored handleSignleArchitecture and handleMultipleArchitectures functions to handle different file formats

- 2.1:

• Refactored the Replacements structure to support multiple sections:
• Added a new 'SectionName' field to the Replacements struct
• Changed 'Replacements' to contain an 'Items' slice of Replacement structs
• Modified the buildReplacements function to return a slice of Replacements, allowing for multiple section definitions
• Updated handleSignleArchitecture and patchArchitecture functions to process multiple sections:
• Now iterates through all defined sections in the Replacements slice
• Applies replacements to each specified section individually
• Adjusted the replaceInSection function to accept a slice of Replacement structs
• Improved error handling and logging:
• Added more detailed error messages for each section processing step
• Included section names in log messages for better traceability
• Enhanced code flexibility and extensibility:
• Made it easier to add new sections for replacement in the future
• Improved code organization by grouping replacement rules by section

- 2.0: support multiple architectures, add more ARM and ARM64 subtypes, add more replacements, macho.File.Section() returns a pointer to macho.Section, add more error handling - 1.0: initial version
