What is this?
Hex encoding is the simplest encoding scheme, representing each byte as two hexadecimal characters (0-9, a-f). Crypto libraries often print keys, IVs, and hash values this way because it's easy for humans to read and copy. It's more verbose than Base64, but its tiny character set makes it a common sight in debug logs.
