add_entry

        # OpenSSL::X509::Name.add_entry

(from ruby core)
### Implementation from Name
---
    name.add_entry(oid, value [, type], loc: -1, set: 0) => self

---

Adds a new entry with the given *oid* and *value* to this name.  The
*oid* is an object identifier defined in ASN.1.  Some common OIDs are:

C
:   Country Name
CN
:   Common Name
DC
:   Domain Component
O
:   Organization Name
OU
:   Organizational Unit Name
ST
:   State or Province Name


The optional keyword parameters *loc* and *set* specify where to insert
the new attribute. Refer to the manpage of X509_NAME_add_entry(3) for
details. *loc* defaults to -1 and *set* defaults to 0. This appends a
single-valued RDN to the end.
