Cryptography Techniques: Everything You Need to Know

WebInsecure use of cryptography is common in most mobile apps that leverage encryption. There are two fundamental ways that broken cryptography is manifested within mobile apps. First, the mobile app may use a process behind the encryption / decryption that is fundamentally flawed and can be exploited by the adversary to decrypt sensitive data. WebFor example, early cryptographic attacks on DES (before it fell to simple brute-force) revealed an attack on eight rounds (the full DES has 16 rounds). With AES-256, there is an attack that works on a simplified version of 10 rounds (the full AES has 14 rounds). ... Replay Attack. A replay attack is one in which the attacker does not decrypt ...
