Difference Between Hash Function and Digest
The major difference between Hash Function and Message Digest is as follows-
|
Hash Function |
Digest(Message Digest) |
|---|---|
|
Hash Function is an algorithm that converts messages into hash |
Digest is the fixed-size combination of letters and numbers |
|
The major work of the hash function is to produce a message digest |
The major work of message digest is to verify the integrity of the message |
|
It is called a hash function because it hashes the input message |
It is called digest because it is made by changing the form of the original message i.e by digesting |
|
Any Hash function is considered good if it produces different digest for different messages |
Any Digest is considered good if it does proper memory management by having different values for different message |
What is the difference between a digest and a hash function?
Digest and Hash Functions are two important aspects of cryptography. In cryptography, we pass an input text from any algorithm that generates some secured text. Now that algorithm is called a hash function and that secured text is called a digest. From here we can conclude that in cryptography we pass original text from the hash function to generate a digest.
