File Hash Online Calculator

What is file hash?

The file uses MD5 SHA1 SHA224 SHA256 SHA384 SHA512 algorithm to generate HASH value. By comparing this value, you can determine whether the file has been modified. This is very meaningful. For example, I downloaded a software from the Internet, but it added some malicious code. However, when you compare it with the hash value on the official website, you will find that it is not the original one from the official website.
The process of generating HASH value by HASH function is one-way and irreversible. Different inputs always output different HASH values, so it is almost possible to modify the file and generate the same HASH value.

How to use file hash calculator

As mentioned above, you need to compare the generated HASH value to determine whether the file has been changed. But how to generate the HASH value of a file? The following introduces how to use the file hash calculation tool.

1. Check the algorithm for the file hash value
2. Select the file whose hash value you want to calculate in the file area above
3. The result will be displayed in a table below the prompt.
