Episode 20 — Hashing, Salting, Digital Signatures, Obfuscation, and Crypto Tools (1.3)
This episode explains several cryptographic concepts that are often confused on the exam. Hashing creates a fixed output used to verify integrity, while salting adds unique random data before hashing passwords to make precomputed attacks harder. Digital signatures support authentication, integrity, and non-repudiation by proving that data was signed with a private key and has not been altered. Obfuscation hides or disguises information but is not the same as strong encryption. Students should also understand crypto tools conceptually, including how they support certificate handling, key generation, hashing, signing, encryption testing, and troubleshooting secure communication problems.
