Abstract
The MD5-SHA checker program calculates and compares the selected hash code of the choosed file. This Java program uses the MessageDigest class, and generate MD5, SHA-1, SHA-256, SHA-384, SHA-512 hash codes. On Windows platform runs the md5hash.jar code with jre1.8.0_131 or higher version of JVM. Under Ubuntu Linux operating system must install the openjdk-8.
$ sudo apt install openjdk-8-jdk openjdk-8-jre-headless
If the default associated program for jar files is java, then download and double click to start. Otherwise the application runs with the following command:
$ java -jar md5hash.jar
How to check hash codes?
- Choose a file or type the path and file name.
- Copy or type the added hash code.
- Calculate and check the selected hash value.
If the typed and calculated hash values are the same:

And the two hash values are different:
