# Fingerprint

A fingerprint is a 256 bit 64 character hexadecimal user identifier for users.
Fingerprints are used in defining users in [transactions](@/transaction_docs.md) and [blocks](@/block_docs.md).

## Fingerprint Generation

A user's finger print is generated via applying SHA256 sum of the user's public RSA key.
