Check MD5 and SHA1 to check file integrity

When downloading files to your computer, you will be wondering if the file is missing or error. If there is a missing part, an error will occur when installing the software. To resolve the situation, when sharing the file will include the MD5 or SHA1 code of the file. We will use a specialized program to check the MD5 and SHA1 codes of the file, see if the file has any errors. And MD5 HashCalc check software is one of the useful tools to check MD5 and SHA1 codes.

MD5 and SHA1 are the types of encryption algorithms. It will convert any large or small character string into a single code. It will read the contents of your file and encode it into MD5 or SHA1. If a missing file or a file is missing or a small part of the file will change the code. So to evaluate a file will be based on MD5 or SHA1 code.

1. Check MD5 with the MD5 check Utility software

MD5 check Utility or MD5 checker is super lightweight tool to check MD5 code. This MD5 code checking software doesn't need to be installed, weighs only 100kb and this is a guide to check MD5 with it.

Download the MD5 checker to your computer, unzip the .zip file and double-click md5.exe to run the utility.

You select Verify an MD5 checksum in the Selection section, usually this section will be selected by default, but to make sure you check again.

Next, copy the MD5 code that the person who shared the file sent to you, then click Paste on the main interface of the software to paste the MD5 code.

Alternatively, you can use the Create an MD5 checksum option to generate MD5 code when you want to share files to others.

2. Check MD5, SHA1 with HashCalc

Step 1:

First, download the HashCalc software to your computer using the link below.

Step 4:

To check MD5 or SHA1 of a file, in the Data Format section select File .

In the Data section, select the 3 dot symbol and select the file you want to check in the computer. Soon in the Data section is the directory path.

Step 5:

Also at that interface, users can choose the type of encryption to test , such as checking MD5, SHA1, REPEMD160, CRC32. Then, click on Calculate to check the file.

Step 6:

After checking, we will get the encryption of the file. You will get this code to compare with the encryption of the file share. If the same means the file is fully downloaded. On the contrary, if the code is not the same, the download file has errors and we will have to reload.

Finally click Close to finish the file checking process.
