        # OpenSSL::X509::Name.to_s

(from ruby core)
### Implementation from Name
---
    name.to_s         -> string
    name.to_s(format) -> string

---

Returns a String representation of the Distinguished Name. *format* is
one of:

*   OpenSSL::X509::Name::COMPAT
*   OpenSSL::X509::Name::RFC2253
*   OpenSSL::X509::Name::ONELINE
*   OpenSSL::X509::Name::MULTILINE


If *format* is omitted, the largely broken and traditional OpenSSL
format (`X509_NAME_oneline()` format) is chosen.

**Use of this method is discouraged.** None of the formats other than
OpenSSL::X509::Name::RFC2253 is standardized and may show an
inconsistent behavior through OpenSSL versions.

It is recommended to use #to_utf8 instead, which is equivalent to
calling
`name.to_s(OpenSSL::X509::Name::RFC2253).force_encoding("UTF-8")`.
