What is a hash?
Hashes are the product of cryptographic algorithms of varying complexity. When a file is run through a hashing algorithm, a sequence of characters is created. This sequence, or hash, is unique to that file. Any changes to the file would alter the hashing and would produce a different result.
Why is checking hashes important?
Most reputable sites that offer file downloads will provide the file’s hash. These hashes are important to check because they verify the file’s integrity. They will confirm that the file wasn’t altered or switched in any way.

What is the difference between MD5 and SHA?
Main Differences Between SHA and MD5 1 The main difference between SHA and MD5 is that SHA connotes a cryptographic hash function developed by NIST, while MD5 is a commonly used hash function that produces a 128-bit hash value from a file with a varying string length. 2 Each abbreviation represents a different full form. SHA stands for the Secure Hash Algorithm, while MD5 stands for the Message Digest Algorithm. 3 The maximum condensation length for each algorithm is different. SHA can process an input message with a maximum length of 2 64 – to – 2 128 bits. This is condensed to form a 160- 512 bit message digest. While MD5 can take a message of any length and condense it into a 128-bit message digest. 4 SHA is comparatively more secured as a cryptographic hash algorithm than MD5. 5 The MD5 algorithm is much faster than the SHA version. However, the optimized SHA1 version was developed as an improvement over the initial algorithm and is considerably faster than MD5. 6 Several serious attacks have been reported over the MD5 algorithm, while the SHA version- especially the improved variants- report fewer attacks. 7 The MD5 algorithm is more susceptible to cyber threats and hacker attacks, as its interface is easier to crack as compared to the more improve SHA versions like SHA-1.

Common Hash Functions
- There are several hash functions that are widely used. All were designed by mathematicians and computer scientists. Over the course of further research, some have been shown to have weaknesses, though all are considered good enough for noncryptographic applications.
Using Hash Values For Validation
- A typical use of hash functions is to perform validation checks. One frequent usage is the validation of compressed collections of files, such as .zip or .tar archive files. Given an archive and its expected hash value (commonly referred to as a checksum), you can perform your own hash calculation to validate that the archive you received is complete and uncorrupted.
