SSHFP record

A Secure Shell fingerprint record is a type of resource record in the Domain Name System (DNS) which identifies SSH keys that are associated with a host name. The acquisition of an SSHFP record needs to be secured with a mechanism such as DNSSEC for a chain of trust to be established.

Structure
; : The name of the object to which the resource record belongs (optional) ; : Time to live (in seconds). Validity of Resource Records (optional) ; : Protocol group to which the resource record belongs (optional) ; : Algorithm (0: reserved, 1: RSA, 2: DSA, 3: ECDSA, 4: Ed25519, 6: Ed448) ; : Algorithm used to hash the public key (0: reserved, 1: SHA-1, 2: SHA-256) ; : Hexadecimal representation of the hash result, as text == Example ==
Example
In this example, the host with the domain name host.example.com uses a Ed25519 key with the SHA-256 fingerprint 123456789abcdef67890123456789abcdef67890. This output would be produced by a ssh-keygen -r host.example.com. command on the target server by reading the existing default SSH host key (Ed25519). In newer releases of the OpenSSH suite, ssh-keyscan -D $HOSTNAME can be used to produce a similar result, by connecting to the host over the network. == See also ==
