Create SHA-512 Hash in Javascript
There’s nothing I love more than unraveling the complexities of code, and today, we’re going to embark on an exciting journey together. As a seasoned developer, I have to say, data integrity is one of those topics that always manage to ignite my interest. So, today, we’ll delve into the world of SHA-512 hash creation, but with a twist—we’re doing it in JavaScript. Yes, that’s right! By the end of this discussion, you’ll be well-versed in creating SHA-512 hashes in Javascript, a handy skill to have up your developer’s sleeve.
Encryption and hashing have served as the foundation for new security modules, among other network security developments. One of the most used hash algorithms is the Secure Hash Algorithm(SHA) with a digest size of 512 bits, or SHA 512.
The SHA-512 hashing algorithm is currently one of the best and secured hashing algorithms after hashes like MD5 and SHA-1 has been broken down. Due to their complicated nature it is not well accepted and SHA-256 is a general standard, but the industry is slowing moving towards this hashing algorithm.
SHA-512 is a part of the SHA 2 family of algorithms, where SHA stands for Secure Hash Algorithm. It was a joint effort between the NSA and NIST to introduce a successor to the weaker SHA 1 family. SHA2 was published in 2001 and has been effective ever since.
The hash function generates the same output hash for the same input string. This means that, you can use this string to validate files or text or anything when you pass it across the network or even otherwise. SHA-512 can act as a stamp or for checking if the data is valid or not.
SHA-512 hasn’t gained the popularity that SHA-256 is experiencing or even other types of newer hashing algorithms when it comes to real-world use in blockchain. That being said it does have a few non-blockchain applications that are noteworthy.
The 512 in the name SHA-512 refers to the final hash digest value, meaning that regardless of the amount of plaintext or cleartext, the hash value will always be 512 bits.

Create SHA3-256 Hash in Javascript
As a web developer, I’m continuously fascinated by the intricate world of cryptographygraphic hash functions. Their use in ensuring data integrity is unparalleled, and one such function that has caught my eye is SHA3-256. Today, I’m thrilled to take you on a journey, illustrating how to create a SHA3-256 Hash in Javascript. It’s a cutting-edge cryptographygraphic function that’s both robust and secure, so buckle up and prepare to dive deep into the captivating world of hashing!
Encryption and hashing have served as the foundation for new security modules, among other network security developments. One of the most used hash algorithms is the Secure Hash Algorithm(SHA) with a digest size of 256 bits, or SHA 256. Although there are numerous variations, SHA 256 has been the most often used in practical applications.
SHA-3 (Secure Hash Algorithm 3) is the latest member of the Secure Hash Algorithm family of standards. Although part of the same series of standards, SHA-3 is internally different from the MD5-like structure of SHA-1 and SHA-2. SHA-3 instances are drop-in replacements for SHA-2, intended to have identical security properties. The SHA-3 family consists of six hash functions with digests (hash values) that are 128, 224, 256, 384 or 512 bits: SHA3-224, SHA3-256, SHA3-384, SHA3-512, SHAKE128, SHAKE256.
The SHA-3 or Keccak algorithm is one of the most secure and efficient hashing algorithms and some claim that it won’t be cracked in the next 20 — 30 years. Developments in the quantum computing world might decrease that time frame but it is still one of the best hashing algorithm we have got right now.
The hash function generates the same output hash for the same input string. This means that, you can use this string to validate files or text or anything when you pass it across the network or even otherwise. SHA3-256 can act as a stamp or for checking if the data is valid or not.
The 256 in the name SHA3-256 refers to the final hash digest value, meaning that regardless of the amount of plaintext or cleartext, the hash value will always be 256 bits.
