The public part of an asymmetric cryptography key pair. It can be safely distributed and is used for example to verify digital signatures, encrypt data for the owner of the private key, or authenticate SSH connections.
Why it matters
The public half of a key pair: it can be shared without risk. Used to verify signatures and encrypt messages that only the private key owner can decrypt.
What's missing without it
Without separating keys into public and private, secure communication would require a prior, confidential agreement of a secret with each party.
When it is used
When adding SSH access to a server, verifying digital signatures, or setting up encrypted communication.
How we use it
The administrator's public SSH key is stored on the server to accept logins using the corresponding private key.
