What is MD5 Modification Tool?
MD5 Modification Tool is a simple and practical web application that is used to slightly modify the content of a file and generate a new MD5 hash value while keeping the actual content of the file almost unchanged. The tool runs in the local browser, and your files will not be uploaded to any server, ensuring the privacy and security of your data.
Purpose of the tool
- File integrity test: Test the system's reaction to file MD5 checksum
- File deduplication test: Test how the file management system handles files with almost identical content but different MD5
- Digital signature test: Verify whether the signature system correctly identifies modified files
- Educational purpose: Demonstrate that even minor modifications can result in completely different hash values
- System security test: Evaluate the system's sensitivity to changes in file hash values
How to use
- Select file: Click the "Select file" button or drag and drop the file into the specified area
- Modify MD5: Click the "Modify MD5" button and the system will modify the file to the new MD5 value
- View results: View file information in a table, including file name, original size, original MD5 value, and modified MD5 value
