Cryptographic Hashing
Hash functions are widely used data structures in computing systems for activities like message integrity checks and information authentication. They are cryptographically "weak" since they can be solved in polynomial time, but they are difficult to decode.
How does cryptographic hashing work?
Cryptographic hash functions add security characteristics to traditional hash functions, making it more difficult to decipher a message's contents or information about recipients and senders.
Cryptographic hash functions, in particular, display the following three characteristics:
• They are "non-collision." No two input hashes should map to the same output hash.
• They can be concealed. It should be impossible to predict a hash function's input value from its result.
• They should be enjoyable to solve. Selecting an input that produces a pre-defined output should be tough. As a result, the input should be chosen from a wide range of possibilities.
Where is cryptographic hashing used?
Cryptographic hash functions are commonly employed in cryptocurrencies to anonymously transmit transaction data. Bitcoin, the first and largest cryptocurrency, for example, employs the SHA-256 cryptographic hash function in its algorithm. Similarly, IOTA, an Internet of Things platform, includes its own cryptographic hash function, Curl.
Hashes, on the other hand, have additional uses in the actual world, such as password verification, signature generation and verification, or verifying file and message integrity
Hashing is also used in cybersecurity.
