WebA cryptographic hash function maps data of arbitrary size to a fixed size, and has some special properties. A rough specification of a hash function is as follows: hash (value: array) -> vector (for some fixed N) An example of a hash function is SHA1 , which is used in Git. WebCryptographic keys can “wear out”. The easiest solution for this is regular key rotation. If this looks like it will still be an issue for you, seek out a mode/library designed to avoid this (such as the AWS Encryption SDK) or find an expert. Working around this problem is beyond the current scope of this document.
