WebCryptographic hashing refers to coding the information or data on blockchain into an unreadable, unhackable text. This is done using a special kind of hashing algorithm known as SHA-256 (Secure Hash Algorithm). It creates a 32-byte long hash value. The hash is always of a fixed length no matter what the length of the input value was. WebHashing is the cryptographic technique that converts data that can be any form into a unique string. Regardless of size or type, any data can be hashed using a hashing algorithm. It takes data of random length and …
