You can extract hash values ​​from text, files, and folders (all files inside a folder) and use them as fingerprints.
Even the slightest change to text, files, or folders completely changes the hash value.
By extracting the hash value and comparing it to the previous hash value, you can determine whether the contents of the text, file, or folder have been altered, forged, or corrupted.
If the content is not changed, the same hash value is extracted every time it is extracted, and if the content is changed even by one character, a completely different hash value is extracted.
This app extracts the hash value of text, file, folder, etc., stores and compares the extracted hash value, and provides the convenience of management.
