New Approaches for Building Cryptographic Hash Functions

New Approaches for Building Cryptographic Hash Functions

Cryptographic hash functions are a fundamental primitive, utilized in numerous security applications. With the recent attacks against many widely deployed hash functions (e.g., MD5, SHA-1), the search is on for new, secure hash functions to re-establish security of all the various protocols that rely on them. At the same time, hash functions ...

Day 23/365, follow me for more such content Your password is NEVER stored as plain text. Instead, apps store a hashed version of your password. Here’s what happens: 1️⃣ You type your password 2️⃣ The app runs it through a cryptographic hash function (like bcrypt / Argon2) 3️⃣ The output is a random-looking hash 4️⃣ Only this hash is saved in the database 🔒 Why hashing? * Hashing is one-way (cannot be reversed) * Even developers cannot see your password * If the database is hacked, attackers get

Password cracking 101 - MD5 is broken! MD5 (Message-Digest Algorithm 5) is a widely known cryptographic hash function developed by Ronald Rivest in 1991, which produces a 128-bit (16-byte) hash value, typically represented as a 32-character hexadecimal number. It was originally designed to verify data integrity by generating a unique digital fingerprint of input data, ensuring that even small changes in the input produce significantly different hash outputs. However, MD5 is now considered crypto
