Module Dns.SshfpSource

Secure shell fingerprint

The secure shell (SSH) applies trust on first use, and can store fingerprints as SSHFP records in DNS, which is then used as a second channel.

Sourcetype algorithm =
  1. | Rsa
  2. | Dsa
  3. | Ecdsa
  4. | Ed25519
  5. | Unknown of int
    (*

    The type of supported algorithms.

    *)
Sourceval algorithm_to_int : algorithm -> int

algorithm_to_int a is the 8 bit integer representation of algorithm a.

Sourceval int_to_algorithm : int -> algorithm

int_to_algorithm i decodes i to the algorithm constructor.

Sourceval pp_algorithm : algorithm Fmt.t

pp_algorithm ppf a pretty-prints the algorithm a on ppf.

Sourcetype typ =
  1. | SHA1
  2. | SHA256
  3. | Unknown of int
    (*

    The type of supported SSH fingerprint types.

    *)
Sourceval typ_to_int : typ -> int

typ_to_int t is the 8 bit integer representation of typ t.

Sourceval int_to_typ : int -> typ

int_to_typ i decodes i to the typ constructor.

Sourceval pp_typ : typ Fmt.t

pp_typ ppf t pretty-prints the typ t on ppf.

Sourcetype t = {
  1. algorithm : algorithm;
  2. typ : typ;
  3. fingerprint : string;
}

The type of a SSH fingerprint record, consisting of algorithm, typ, and actual fingerprint.

Sourceval pp : t Fmt.t

pp ppf t pretty-prints the SSH fingerprint record t on ppf.

Sourceval compare : t -> t -> int

compare a b compares the SSH fingerprint record a with b by comparing the individual fields in order.
