X.500 distinguished name

type attribute =

| CN of string
| Serialnumber of string
| C of string
| L of string
| ST of string
| O of string
| OU of string
| T of string
| DNQ of string
| Mail of string
| DC of string
| Given_name of string
| Surname of string
| Initials of string
| Pseudonym of string
| Generation of string
| Street of string
| Userid of string
| Other of Asn.oid * string

The variant of a relative distinguished name component, as defined in X.500: an attribute type and value.

module Relative_distinguished_name : Stdlib.Set.S with type elt = attribute

Relative_distinguished_name is a set of attributes.

type t = Relative_distinguished_name.t list

A distinguished name is a list of relative distinguished names, starting with the most significant component.

val equal : t -> t -> bool

equal a b is true if the distinguished names a and b are equal.

val make_pp : 
  format:[ `RFC4514 | `OpenSSL | `OSF ] ->
  ?spacing:[ `Tight | `Medium | `Loose ] ->
  unit ->
  t Fmt.t

make_pp () creates a customized pretty-printer for t.

parameter format
Determines RDN order, escaping rules, and the default spacing:
- `RFC4514 produces the RFC4514. RDNs are written in reverse order of the ASN.1 representation and spacing defaults to tight.
- `OpenSSL produces the a format similar to OpenSSL. RDNs are written in the order of the ASN.1 representation, and spacing defaults to loose.
- `OSF emits RDNs in the order they occur in the ASN.1 representation, each prefixed by a slashes, using tight spacing. This format is designed by analogy to RFC4514, substituting slash for comma an semicolon, and may currently not be fully compliant with the OSF specifications.

parameter spacing
Determines whether to add space around separators:
- `Tight to not add any redundant space,
- `Medium to add space after comma and around plus signs, and
- `Loose to also add space around equality signs.
This parameter is currently ignored for the OSF format.
The pretty-printer can be wrapped in a box to control line breaking and set it apart, otherwise the RDN components will flow with the surrounding text.

val pp : t Fmt.t

pp ppf dn pretty-prints the distinguished name. This is currently Fmt.hbox (make_pp ~format:`OSF ()). If your application relies on the precise format, it is advicable to create a custom formatter with make_pp to guard against future changes to the default format.

val common_name : t -> string option

common_name t is Some x if the distinguished name t contains a CN x, None otherwise.

val decode_der : string -> (t, [> `Msg of string ]) Stdlib.result

decode_der cs is dn, the ASN.1 decoded distinguished name of cs.

val encode_der : t -> string

encode_der dn is octets, the ASN.1 encoded representation of the distinguished name dn.
