    API

    getCommonNames(buffer[, encoding])

    Extracts common names (with "alternative" if present) from buffer. Both der and pem encodings supported.

    toRegEx(names)

    Generates regular expression that match any of common name extracted before. Supports RegEx simplification, so wildcard and non-wildcard domains are grouped into single expression.
