Hash CheckSum is a free utility for calculating hashes from given text or from files stored on the device.

Fast and simple application for generating and comparing MD5, SHA-1, SHA-224, SHA-256, SHA-384, SHA-512 and CRC-32 hashes of files or text.

The calculated hash can be copied to the clipboard for reuse elsewhere.

The first tab allows to calculate the hash of the given string.
The second tab helps you count hash files located in the internal or external memory of your device. The file size and the last modified date are also displayed.

The last feature helps you compare calculated hashes with other hashes, but in general, you can compare any hash by simply pasting it.

A hash (also called a checksum or digest) is a digital fingerprint, which uniquely identifies a string or file.

The hash function is often used in cryptography to generate strong passwords. They are also used to check file integrity.
