Online SHA-384 hash generator
Since the SHA-2 algorithm was published, it has gained a massive audience and application cases. This growth is a result of how secure its hashing pattern is.
Several cryptographic hashes make up the SHA-2 algorithm. The National Security Agency (NSA) first published it in 2001. They followed Merkle-Damgård's construction. The SHA-2 consists of six hashes with message digests that are 224, 256, 384 or 512 bits.
These six hashes include: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, and SHA-512/256.
This article will discuss the SHA-384, highlighting its benefits and use cases.
What is the Sha-384 hash?
As part of the SHA-2 algorithm, the Sha384 hash outputs a 384 bits message digest. It succeeds Sha256 immediately. It has a block size of 1024 bits and a word size of 64 bits. Each block of the message requires 80 rounds to be processed. It is approximately 50% faster than the SHA-224 and SHA-256.
Properties of the Sha-384
Hash functions convert input strings of any length into fixed-length output strings called hashes at their base state.
Not only do they have the property above, but they are also:
- Deterministic, in the sense that a given input generates the same output.
- A one-way function. A given output value cannot realise the input value.
- Collision resistant. This implies two inputs cannot result in the same hash.
- Fast to calculate. This is because it is computed in 64-bit word size.
- Alter sensitive. Therefore, even small changes in the input result in different hash outputs.
About the Online Sha384 hash generator
Just like most hash, the sha384 hash has its generators. These are free tools designed to create hashes from user inputs. Hence, we have the Freenerdtool designed online sha384 hash generator tool.
How to Generate Sha384 hash online
Now, let's use the Freenerdtool to generate a SHA384 hash. The following steps will guide us:
Let's begin by visiting Freenerdtool's sha-384 free online hash generator.
Next, type or copy and paste into the provided text area in the tool. For instance, let's type in "Hello world".
Lastly, click the "Submit" button to submit the input value. Then the online tool will process the input and output a value. Now, we will receive a hash "9203b0c4439fd1e6ae5878866337b7c532acd6d9260150c80318e8ab8c27ce330189f8df94fb890df1d298ff360627e1".
Use cases for the Sha384 hash
As a secure algorithm, SHA-384 has several applications. Some of these include:
- Password hashing.
- Email hashing.
- Integrity Check of Data.
- Application in Government Data Protection.
Apart from these common uses, SHA384 has many other use case. They are also seen in some security protocols like:
Secure Shell(SSH), Internet Protocol Security(IPSec), and Transport Layer Security(TLS).
Comparison between Sha-384 and Sha-224 hash
When comparing Sha384 and Sha224, the Sha384 is roughly 50% faster on a 64-bit machine. The main difference between Sha384 and Sha224 is the size of the output. While Sha384 produces a 384-bit (48 byte) output, Sha224 produces a 224-bit (28 byte) output. The larger output size of Sha384 offers more security than the smaller one from Sha224. However, both hashes are resistant to length extension attacks.
The sha384 hash is not as popular with the public as its predecessor, the sha256. However, it is a viable alternative to 256 when looking for speed. Additionally, it is resistant to length extension attacks, unlike the 256 and sha-512.
