This post analyzes and compares the security of SHA256, SHA512 and MD5 hash algorithms. It finds SHA512 to be the most cryptographically secure hash overall, with SHA256 a close second, and MD5 considered broken.

Reasons why SHA512 is superior to MD5

MD5, or Message-Digest Algorithm 5, creates a 128-bit hash value. This is like creating a unique fingerprint that is 128 characters long. It's powerful, but it's not perfect. In fact, MD5 has been found to have vulnerabilities that could allow someone to create two different pieces of data with the same hash value. That's a no-no in digital forensics!

On the other hand, SHA-1, or Secure Hash Algorithm 1, creates a 160-bit hash value. That's a fingerprint that is 160 characters long! SHA-1 is considered more secure than MD5, but it also has vulnerabilities. In fact, experts recommend moving to even stronger hash functions like SHA-256 or SHA-3 for critical applications.

So, which hash function should you use? Well, it depends on your specific needs. If you're dealing with less critical data and need to save on processing power, MD5 might be sufficient. But if you're dealing with sensitive data that needs the highest level of protection, consider using SHA-256 or SHA-3. Remember, the choice of hash function could mean the difference between catching a criminal and letting them slip through your fingers.

SHA-2 includes significant changes from its predecessor, SHA-1. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits:[5] SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256. SHA-256 and SHA-512 are novel hash functions computed with eight 32-bit and 64-bit words, respectively. They use different shift amounts and additive constants, but their structures are otherwise virtually identical, differing only in the number of rounds. SHA-224 and SHA-384 are truncated versions of SHA-256 and SHA-512 respectively, computed with different initial values. SHA-512/224 and SHA-512/256 are also truncated versions of SHA-512, but the initial values are generated using the method described in Federal Information Processing Standards (FIPS) PUB 180-4.
SHA-2 was first published by the National Institute of Standards and Technology (NIST) as a U.S. federal standard. The SHA-2 family of algorithms are patented in the U.S.[6] The United States has released the patent under a royalty-free license.[5]
As of 2011, the best public attacks break preimage resistance for 52 out of 64 rounds of SHA-256 or 57 out of 80 rounds of SHA-512, and collision resistance for 46 out of 64 rounds of SHA-256.[1][2]

SHA-3 (Secure Hash Algorithm 3) is the latest[4] member of the Secure Hash Algorithm family of standards, released by NIST on August 5, 2015.[5][6][7] Although part of the same series of standards, SHA-3 is internally different from the MD5-like structure of SHA-1 and SHA-2.
