Cryptography and hashing
WebIntroduction. This article provides a simple model to follow when implementing solutions to protect data at rest. Passwords should not be stored using reversible encryption - secure password hashing algorithms should be used instead. The Password Storage Cheat Sheet contains further guidance on storing passwords. WebIn cryptography, a salt is random data that is used as an additional input to a one-way function that hashes data, a password or passphrase. Salts are used to safeguard passwords in storage. Historically, only the output from an invocation of a cryptographic hash function on the password was stored on a system, but, over time, additional …
