This software is open source. You can obtain the latest source code from the SHA1 Collision Detection GitHub repository or browse below for the source code associated with a specific release. If you make any changes which you feel improves this application, please let us know via our Contact Page.

Stable version released on 9/11/2008 (Recommended)
Files available with this release: 1
  • Minor performance changes.

Version released on 4/16/2008
  • Minor performance tweaks & typo corrections.

  • 1) The /Priority switch now sets the process and thread priority to NORMAL.

    2) If you specify the thread count to be equal to the number of processors (without regard to logical / physical CPUs), the process will set each of the worker threads to a separate ideal processor.
    Note: The process will NOT set the threads CPU affinity, it only sets the CPU "Ideal Process" which acts as a hint to the internal windows thread scheduler.

    3) The process now employs the use of a "wait event" to monitor thread completion as opposed to the polling method which was used in the past versions.

    4) Corrected several "typos".
  • Fixed under/over flow issue.

  • Resolved two issues which would cause the process to run indefinitely:

    1) Converted all character generation functions to use unsigned chars.
    2) You can now only generate strings with characters between 0 and 254 (this version ommits ascii character 255).

Version released on 2/8/2008
  • Version is a complete rewrite from previous versions with many internal changes.
  • Rewrote the string generator to be completely thread safe. Also fixed issue where not all combinations were being generated due to a bug in the load distribution scheduler.
  • Added new command line parameters.
  • Added new command line parameters. These new parameters give you full control over generation functionality.

    /Hash: 40 character SHA1 hash value.

    /Start: Optional - The starting length of the collision check.

    /Len: The ending length of the collision check.

    /Min: The starting ASCII character of the character range to use in generation.

    /Max: The ending ASCII character of the character range to use in generation.

    /Priority: Runs the application at normal priority, Default is low.
