Hashing

Hashing is widely used in real-time scenarios for efficient data processing and security. In password storage, it ensures user credentials are securely stored by hashing passwords before saving them. In blockchain technology, hashing links blocks together, ensuring data integrity. Hashing is also key in load balancing, where server requests are routed based on hashed data to distribute traffic evenly. In data deduplication, hash values help identify and remove duplicate files, saving storage space. Additionally, hashing is used for fast data retrieval in databases, integrity checks in data transmission, and detecting fraud or malware by comparing known hashes.
