hashing

Hashing is the process of using a hash function to convert data into a unique code or hash value. It is commonly used for data integrity checks, encryption, and efficient data retrieval.

How can you compare hashing and encryption for information security?

Hashing and encryption are both cryptographic techniques used for information security, but they serve different purposes. Hashing is a one-way function that converts data into a fixed-length string of characters, while encryption is a two-way process that transforms data into a coded format that can be reversed using a key. Hashing is primarily used for data integrity verification and password storage, while encryption is used to protect data confidentiality during transmission or storage.

How can I handle and store user passwords securely in my web application?

Storing user passwords securely in a web application is crucial to protect user accounts from unauthorized access. One of the best practices is to hash and salt passwords before storing them in the database. This involves using cryptographic algorithms to convert passwords into a fixed-length string of characters that cannot be reversed. Additionally, using a unique salt for each password adds an extra layer of security by preventing attackers from easily cracking the passwords using rainbow tables or precomputed hashes.
