The MD5 & SHA Checksum Utility is a tool developed by Raymond Lin. With this tool, users can verify the integrity of a file through its hash signatures. It can generate different hash functions such as  MD5, SHA-1, SHA-256, and SHA-384 signatures, and users can verify whether the hash functions match or not using the tool. The MD5 & SHA Checksum Utility has a simple interface and it’s very easy to use since all you have to do is input the file and click the hash generator that you need. One great thing about the tool is that it is completely portable, which means you can carry it around with you wherever you go. If you need a file manager that can check hash functions, the MD5 & SHA Checksum Utility is a good choice.
