Online SHA-224 hash generator

The Secure Hash Algorithm (SHA) is a family of cryptographic hash function published by the National Institute of Standard and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), which include:

  • SHA-0
  • SHA-1
  • SHA-2 suite
  • SHA-3

For this article, we will discuss how to generate hashes using SHA224, a member of the SHA-2 suite.

What is the SHA224 hash

The Sha224 algorithm is part of the Sha-2 algorithm suite and is based on the Sha256 algorithm. It was first published in 2004 and produces a hash of 224bit. The SHA-224 has a block size of 512 bits, and the initial input is divided into 32-bit words for processing. Each block of data goes through 64 rounds of operations before the final hash is produced.

What is it used for

The SHA-224 hash algorithm can be found in several security technologies:

  • Transport Layer Security(TLS)
  • Internet Protocol Security(IPSec)
  • Pretty Good Privacy(PGP)
  • Secure/Multipurpose Internet Mail Extensions(S/MIME)
  • Secure Shell(SSH)

Also, asides from being the core component of the above protocols, they can be used for :

  • Authenticating data
  • Password Hashing
  • Blockchain technologies

About the online SHA224 Hash Generator Tool

The sha224 hash generator is an online tool that helps a user generate sha224 hash seamlessly. It accepts user input and generates a fixed output hash value. As a result, developers and other users do not have to manually create an algorithm to create these hashes.

How to Generate SHA224 Hash

Generating a hash from the Freenerdtool free online SHA-224 hash generator tool can be achieved through the following steps:

  • Step 1: goto the Freenerdtool online SHA-224 generator website.
  • Step 2: type or copy and paste the string you wish to hash into the text area provided
  • Step 3: Now submit the string by clicking on the submit button, and the tool processes your input and generates the SHA-224 hash value equivalent.

Now let's look at an example: Type in the following "Hello World" and click submit. Next, we will see a value: "ac230f15fcae7f77d8f76e99adf45864a1c6f800655da78dea956112" generated just below the input area. This value is the Hashed equivalent of the "Hello world".

Advantages of the SHA-224 hash

SHA-224 hash algorithm has the advantages of being:

  • One-way functions: If given an SHA-224 hash value, it will be impossible to decode the input string that generated it. Many online security systems assume these attacks are impractical since they cannot determine a suitable input from the SHA-224 hash.
  • Collision-resistant: Two inputs cannot produce the same hash.
  • Fast to calculate: When an input string is keyed into a hash generator, the generated hash shows up almost immediately.
  • Deterministic: This implies that the input string of the same value generates the same hash output. For instance, the hash output for "Hello World" will always be "ac230f15fcae7f77d8f76e99adf45864a1c6f800655da78dea956112".

SHA-224 vs SHA-256

As with SHA-224, SHA-256 has the same block size, operation rounds, and word size. However, SHA-256 outputs 256 bits, whereas SHA-224 outputs 224 bits. Also, because of the length of SHA-256 hash output, it is commonly referred to as a secure hashing algorithm.

Is sha224 secure?

There is no definitive answer to this question as the security of a hash function depends on a number of factors. However, SHA-224 is generally considered to be a secure hash function.
