The resulting hash is unique to the original data and is often used for data verification and integrity checks. _ Hashing is the process of converting data into a fixed-length string of characters using a mathematical algorithm
• Used to securely store passwords by hashing them and comparing the hash values during authentication.• Employed in digital signatures and blockchain technology to ensure data integrity.
Hashing is a one-way function that converts data into a fixed-length output, while encryption is a reversible process that converts data into ciphertext and back into plaintext.
Even if the database is compromised, attackers cannot reverse the hash to retrieve the original password. Hashing secures passwords by converting them into unique hashes, which are stored in databases
However, MD5 and SHA-1 are considered weak and have been replaced by stronger algorithms like SHA-256. Common algorithms include MD5, SHA-1, and SHA-256
