Hash Collider 0.5.0
2.543

2.543

Purpose of this tool is to help modders to reverse Jenkins hashes to original strings or find compatible random collisions, which can be used instead of hash in XML files.
Application contains english dictionary and also dictionary from words fround in GTA, which can be used to brute-force hashes. Also dictionary of already known hash names is included to instantly resolve community known hashes.
THIS TOOL IS WORK-IN-PROGRESS AND NOT FEATURE COMPLETE!

CHANGE LOG
version 0.5.0:
Main purpose of this release was heavy refactoring of rest of the UI to completely remove lag during search and unlock limits of HashCollider even further. UI now can handle tens of thousands of hashes and millions resolved strings without any issues. This change mainly justifies moving HashCollider across v0.5 milestone.
- Changed list view in "Found matches" with custom/in-house tree view implementation, which heavily improves performance. This also adds possibility and collapse/expand hash groups at will
- Added counter to "Hash list" tab showing of number of added hashes/dictionary matches/random collisions/resolved strings in list
- Added counter to "Found matches" tab showing how many hash groups/hash names is found in list
- Added searching feature for possibility to limit resolved strings to exact number of characters (will be optimized further in future updates)
- Added current hashrate/speed in progress bar
- Whitespace characters around inserted hashes are now ignored (around inserted strings was ignored before already)
- Fixed bug, when application was unable to load dictionaries when placed in path containing non-ascii characters
- Fixed bug, when multiple same strings were found, which was caused by combination of different words making same string (all found strings are now deduplicated before adding into result list)
- Fixed bug, when sometimes checking resolved string in "Found matches" tab does not copy string into "Hash list" tab
- Fixed possible division by zero exception when starting search
- Further code optimizations and refactoring, improving performance and reducing EXE size by roughly 30%
version 0.4.9:
- IMPORTANT: Fixed new bug introduced in 0.4.8, when adding strings instead of hashes did not added hashes into the list
- Replaced all internal dictionaries/hash tables with more optimized ones
- Further improved speed of adding new hashes and hashnames (approximately 100.000 per second)
- Optimized synchronization code of thread searching for random collisions, leading to better performance and CPU utilization
- Other performance improvements across the app
version 0.4.8:
- Completely rewritten code around hash list view, now using much faster virtual mode. Because of this, working with thousands of hashes is fast and without long delays and UI lagging (2nd list of resolved names is not affected and does not use this optimization)
- Fixed position of Threads select when window is resized
version 0.4.7:
- Added support for adding hashes also as Int32 (negative decimal values) when format set on "dec"
- Added checkbox "Update ListBox" to "Found matches" tab - unchecking will pause adding new findings into list, which saves CPU time to update UI and you can also look into list without constant jumps of content
- Added option "Try also without separator" into "Resolver settings" form to try connect words with and without separator also (which is needed if you are not sure if separator is present, or it might not be present between every word, for example "VehicleSpeed_Default" which is not "VehicleSpeedDefault" nor "Vehicle_Speed_Default")
- Added possibility to add multiple word separators into "Resolver settings" which allows you to search all combinations (if you add "_,-" you will search "a_b_c", "a_b-c", "a-b_c" and also "a-b-c")
- Added note into "Resolver settings" which tells you how many hashes needs to be tested for 1-2 word and 1-3 word combination, which might help you to guess how extensive searching it will be
- Added separate code for resolving single hash, which leads to approx. 5% speed boost
- Improved searching thread synchronization which results in less lags and freezes and better CPU utilization, especially during UI update when match found
- Fixed irregular bug with division by zero error
- Updated memory manager
version 0.4.6:
- Added icons into main menu, popup menu and hash list, including icon informing user which hashes are currently in search
- Added field "Must ends with" to specify phrase with which found name must ends in resolver settings
- Added option "Add checked names to custom dictionary" to popup menu in "Found matches" list
- Unlocked menu item File > New project (Ctrl+N) to clear everything with one click and start over
- Added menu Help with some usefull links and information
- Added warning when resuming search after changing hash list to inform user that changes will not affect resumed search
- Added options "Don't search where dictionary match/random collision/resolved string already exists" in resolver settings
- Fixed bug where "Copy selected resolved string(s), dictionary match(es) or collision(s)" did not actually copied resolved string
version 0.4.5
- Optimized resolving performance by approx. 22%
- Optimized adding found matches to list to prevent infinite freezing with big batches of hashes
- Added progress bar for resolving hashes to show in what part of n-word combination search is
- Other minor fixes, improvements and performance optimizations
version 0.4.4
- Added possibility to Pause / Resume working job
- Fixed bug with "Copy selected hash(es)" which copied wrong binary data instead of selected hash
- Fixed crash on closing app during running job
version 0.4.3
- Implemented multi-threading support, which allows you to boost resolving speed by number of your CPU cores (for now working only for dictionary brute-force resolving, not for random collision search)
- Added scrollbars to textareas
- Fixed bug, where long lines in textareas were wrapped and added as individual lines
- Replaced memory manager (improves performance a little)
- Fixed few memory leaks
- Small cleanup of dictionary
hotfix version 0.4.2.1
- Fixed serious bug when resolving with prefixes found collisions only for first prefix in list (sorry about that, but if you searched with prefixes and did not find what you were looking for, you should repeat search now)
- Fixed bug where decimal hashes were not accepted above signed int max (2147483648 and up)
version 0.4.2:
- Added option to add hashes in decimal format
- Added "Select all" option to context menus
- Added separate text box for adding hashes computed from strings
- Added separate column "Resolved string" for strings resolved by dictionary brute-forcing
- Branched popup menu items "Delete selected" and "Delete all" in "Hash list" to allow deleting content of any column
- Branched popup menu items "Copy selected name(s)" in "Found matches" to allow copying names only or grouped names
- Fixed drawing and component positioning issues when form is resized
- Fixed progress bar stretching and animating issue
- Fixed bug which allowed to rename item in list views, which actually had no effect
- Fixed bug where checking name in "Found matches" did not transfer it to "Hash list" table in some cases
- Fixed bug where certain event was fired too often during hash resolving, which could lead to performance degradation on long lists
- Updated US dictionary, now containing also inflected variants and plurals
Application contains english dictionary and also dictionary from words fround in GTA, which can be used to brute-force hashes. Also dictionary of already known hash names is included to instantly resolve community known hashes.

Glad to see this in the public. Hopefully the community will take an interest in helping find these hashes! Great work.
Sounds useful. Could you make a demonstration video for it?
@MrGTAmodsgerman I will try to make some instructional video when I will implement all planned features.
@dav90 Ok ;)
@MrGTAmodsgerman So my friend Dilapidated made tutorial video for me, you can check it above in image section :)
@dav90 Thank you and your friend
Thanks ;)
@dav90 excellent work
Awesome update <3
