SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that produces a fixed-size, 256-bit (32-byte) hash value from an input of any size. It is a member of the SHA-2 family of hash functions, which includes SHA-224, SHA-256, SHA-384, and SHA-512. SHA-256 was developed by the National Security Agency (NSA) and was standardized by the National Institute of Standards and Technology (NIST).

What is a cryptographic hash function ?

A cryptographic hash function is a mathematical algorithm that takes an input (or 'message') and produces a fixed-size string of characters (the 'hash value'), which represents the data in the input. The main characteristics of a cryptographic hash function are:

Deterministic: Given the same input, the hash function will always produce the same output. One-way: It is computationally infeasible to determine the input from the output, or to find two different inputs that produce the same output. Collision-resistant: It is computationally infeasible to find two different inputs that produce the same output. Cryptographic hash functions are widely used in various applications, such as password storage, digital signatures, and data integrity checks.

How does SHA-256 work ?

SHA-1 follows the same basic structure as other cryptographic hash functions, such as MD5 and SHA-2. It takes the input message, processes it through a series of mathematical operations, and produces the output hash value.

The input message is first padded to ensure that it is a multiple of a certain block size. Then, the message is divided into blocks, and each block is processed through a series of logical operations, called 'rounds.' The output of each round is combined with the input of the next round, until all the blocks have been processed.

The exact details of the mathematical operations performed in each round are complex and beyond the scope of this article, but they involve bitwise operations (such as AND, OR, and XOR) and modular arithmetic.

Why is SHA-1 considered secure ?

SHA-1 was designed to be resistant to attacks that could be used to find collisions (two different inputs that produce the same output). When it was first released, it was considered to be a secure hash function, and it was widely used for various purposes, such as verifying the integrity of downloaded files and generating digital signatures.

However, it is important to note that no cryptographic hash function is completely secure and that all hash functions are vulnerable to attacks to some degree. The security of a hash function depends on the amount of computational power required to find collisions and on the rate at which computational power is increasing.

What are some applications of SHA-256?

SHA-256 is widely used in various applications that require a high level of security, such as:

Password storage: Many websites and applications use SHA-256 (or another cryptographic hash function) to store passwords securely. When a user creates a password, the hash function is used to create a hash value from the password, which is then stored in the database. When the user tries to log in, the password is hashed again and compared to the stored hash value. If the two hash values match, the password is considered to be correct.

Digital signatures: SHA-256 is often used to create digital signatures, which are used to authenticate the identity of the sender and to ensure the integrity of the message. A digital signature is created by combining the message with the sender's private key to create a hash value, which is then attached to the message. The recipient can verify the authenticity of the signature by using the sender's public key to recreate the hash value and comparing it to the attached hash value.

Data integrity checks: SHA-256 can be used to verify the integrity of data, such as files or messages, by creating a hash value from the data and comparing it to a stored hash value. If the two hash values match, the data is considered to be unchanged.

Cryptocurrency mining: SHA-256 is used as the proof-of-work algorithm in some cryptocurrencies, such as Bitcoin. In this application, miners compete to find a solution to a mathematical problem that involves computing a hash value that meets certain criteria. The first miner to find a solution is rewarded with a certain number of cryptocurrency coins.

Other applications: SHA-256 is also used in other applications that require a secure hash function, such as secure communication protocols and data deduplication systems.
