An **Extendable-Output Function** (EOF) is a concept from cryptography, particularly in the context of cryptographic primitives used for securing communications and data. It refers to a type of function that can produce an arbitrary amount of output from a relatively small amount of input. This property makes EOFs useful for applications like key derivation and secure multi-party computations.
