MD5 & Sha Checksum Utility Download Free

Checksums are a fundamental tool in verifying data integrity, used to check if files have not been altered or corrupted during transmission or storage. Among the most widely used checksum algorithms are MD5 (Message-Digest Algorithm 5) and SHA (Secure Hash Algorithm). This article explores these algorithms, their utility, and their applications.

What is a Checksum?
A checksum is a value computed from the data of a file or a message. It’s a kind of fingerprint of that data, and allows users to check whether their data is unchanged. Whenever a file is sent or stored, its checksum can be calculated and compared to the original. If the checksums match, then probably nothing has happened to the data; if they don’t, then probably something has happened.

MD5 Checksum
Overview
MD5 was invented by Ronald Rivest in 1991. It provides a 128-bit hash value, usually represented in a 32-character hexadecimal number. Though it had widespread usage in data integrity checks, weaknesses have been discovered that make it less secure in cryptographic applications.

Features
Hash Length: 128 bits (16 bytes)
Output Format: Usually represented in hexadecimal
Speed: Fast calculation, making it suitable for large files
Vulnerabilities
Susceptible to collision attacks, that is where two different input results yield the same hash value.
Uses
Verify integrity of files: verifies if any file has changed.
Download checksums; commonly accompany downloading software to test file integrity
Digital Signatures; In some digital signing schemes this has been deployed.
Using MD5 Example
In the Unix-like command prompt to write an MD5 checksum execute the following from your console.
bash
Copy
md5sum filename.txt
This command outputs the MD5 checksum for the specified file.

SHA Checksum
Overview
SHA is a family of cryptographic hash functions, with SHA-1 and SHA-256 being the most commonly used. SHA-1 produces a 160-bit hash, while SHA-256 produces a 256-bit hash, making them more secure compared to MD5.

Hash Length:
SHA-1: 160 bits (20 bytes)
SHA-256: 256 bits (32 bytes)
Output Format: Typically represented in hexadecimal
Security: More robust against collision attacks compared to MD5, especially SHA-256
Uses
Data Integrity: Widely used in SSL/TLS certificates and also in digital certificates.
Blockchain Technology: SHA-256 is the base of other cryptocurrencies including Bitcoin.
Software Distribution: Used to assure the integrity of the packaged software.
Example of SHA
To create a SHA-256 checksum on a Unix-like system you may use;
