# SSHFP

`SSHFP` adds a [SSH Public Key Fingerprint record](https://www.rfc-editor.org/rfc/rfc4255) to the domain. The record contains a fingerprint of a SSH server which can be validated before SSH clients are establishing the connection.

**Algorithm** (type of the key)

| ID | Algorithm |
| -- | --------- |
| 0  | reserved  |
| 1  | RSA       |
| 2  | DSA       |
| 3  | ECDSA     |
| 4  | ED25519   |

**Type** (fingerprint format)

| ID | Algorithm |
| -- | --------- |
| 0  | reserved  |
| 1  | SHA-1     |
| 2  | SHA-256   |

`value` is the fingerprint as a string.
