    WinHasher

    Very simple file and text hashing tool for Windows

    Tiny script will find hash digest of files or text by calling on Microsoft's "certutil.exe", using MD4, MD5, SHA1, SHA256, SHA384, or SHA512. Simple and self explanatory. *EDIT 5/3/25, I just realized that there is another project entitled "WinHasher", it appears to kind of do the same thing but uses native code rather than Microsoft's "certutil". If that's what you're looking for, it's here: https://github.com/gpfjeff/winhasher

    TraySafe

    TraySafe

    Elegant and reliable profile data storage

    ...PIN functionality is included in versions 1.1.0 and above. The serious perk of the app is that all the info is saved as encrypted data in the data.tsf file in the program directory. The simple yet effective encryption algorithm has a password hash, salt key and vigenère cipher key that are changed with every update. The only thing you have to do when updating is to delete the .tsf files and re-enter all your info again so that it can be encrypted using the new parameters. Detailed How-To can be found in the project wiki.

    SHAFT — Simple Hash Functions Test

    Collision tests for third-party hash functions implementations.

    This project conducts collision tests on many hash functions, trying to find options for those interested in leaving SHA-1 (which is kind of imperative these days). Tests are conducted on a per-environment basis, so that each environment will produce some specific results. Also, user can choose criterion such as: * attempts per second; * collision attempts per max attempts supported; and * power consumption.
