rfc2253

An RFC 2253 parser and formatter for X.500/X.501 distinguished names, used in LDAPv3 and SSL certificates. Version 0.2.0 is the latest stable release; the package has infrequent updates. It provides parse, format, and escape functions, plus DistinguishedName and RelativeDistinguishedName classes with methods like match, get, getAll, and has. Unlike alternatives (e.g., ldapjs DN), rfc2253 focuses strictly on parsing and formatting according to RFC 2253 without extra LDAP client features. Requires an ES2015-compatible Map global; for older Node.js versions, a polyfill like core-js may be needed.
