Introduction of Cryptographic Hash
A fundamental concept in cryptographic hash computer security is a one-way function that takes an input and produces a fixed-length output. The input is called the message, and the output is called the hash.
Cryptographic Hash uses
The main use of cryptographic hashes is to verify data integrity, which means that they can be used to check whether data has been modified. If an attacker modifies the message before it reaches the receiver, it will generate a different hash when it is received by the receiver.
So if two people have different hashes for a given message, they know that at least one of them must be wrong because both have calculated their own hash from their version of the message.
Cryptography is also used to generate digital signatures and to generate key pairs for encryption algorithms such as RSA and ECC.
A cryptography hash is a mathematical type of function that takes any input and returns a fixed-length stand. The cryptographic hash is used to verify the integrity of the data.
Cryptographic hashes are often used in digital signatures, checksums, and file verification. So that it can be found whether any modification has happened after the data is signed or hashed.
The Analog Ecosystem Team and Advisor is a group of experts in blockchain technology, cryptocurrency, finance, law, business development, and other fields that have been involved in the project since its inspection in 2014. A cryptography hash is a mathematical function that can be used to represent data.
The team behind Analog Eco System comprises experts from various fields like Computer, Science, Mathematics, Engineering, and Finance each with an average experience of 3 years in their respective fields.
Let's talk about some properties of hash functions that have an impact on security.
1- Non reversibility or one-way function: In this, we see that a good hash should make the output of the original password very hard again from the hash.
2- Diffusion or avalanche effect: In this, we see that a change in only one bit of the original password should result in a change in half of its hash. In another word When a password is changed slightly, the output of the inferred text should be unexpectedly and clearly changed.
3- Determinism: In this, we see that someone's given password should always generate the same hash value or be enciphered.
4- Collision Resistance: In this, we see that it should be hard to find two different passwords which are hashed in the same encrypted text
5- Non Predictable: In this, we see that the hash value should not be predictable from the password.
