encryption key

Secret decoder string

An encryption key is a string of data used to encode or decode information, making it unreadable without the matching key.

Keys function like passwords but are typically longer and generated algorithmically rather than chosen by humans.

In symmetric encryption, the same key locks and unlocks; in asymmetric systems, paired public and private keys work together.

Never share your private encryption key.
