Hashing

Hashing, in cryptographic terms, is the process of converting input data into a fixed-size, unique string of characters using a specific cryptographic algorithm. This output, known as a hash or digest, is unique to the input data, providing a secure way to verify integrity.

Even the slightest change in the original data results in a completely different hash. Hashing is fundamental for digital signatures, blockchain security, and password protection because it allows for quick, secure data comparisons without revealing the original information.
