41/**
42 * This class defines the Extended Key Usage Extension, which
43 * indicates one or more purposes for which the certified public key
44 * may be used, in addition to or in place of the basic purposes
45 * indicated in the key usage extension field. This field is defined
46 * as follows:<p>
47 *
48 * id-ce-extKeyUsage OBJECT IDENTIFIER ::= {id-ce 37}<p>
49 *
50 * ExtKeyUsageSyntax ::= SEQUENCE SIZE (1..MAX) OF KeyPurposeId<p>
51 *
52 * KeyPurposeId ::= OBJECT IDENTIFIER<p>
53 *
54 * Key purposes may be defined by any organization with a need. Object
55 * identifiers used to identify key purposes shall be assigned in
56 * accordance with IANA or ITU-T Rec. X.660 | ISO/IEC/ITU 9834-1.<p>
57 *
58 * This extension may, at the option of the certificate issuer, be
59 * either critical or non-critical.<p>
60 *
61 * If the extension is flagged critical, then the certificate MUST be
62 * used only for one of the purposes indicated.<p>
63 *
64 * If the extension is flagged non-critical, then it indicates the
65 * intended purpose or purposes of the key, and may be used in finding
66 * the correct key/certificate of an entity that has multiple
67 * keys/certificates. It is an advisory field and does not imply that
68 * usage of the key is restricted by the certification authority to
69 * the purpose indicated. Certificate using applications may
70 * nevertheless require that a particular purpose be indicated in
71 * order for the certificate to be acceptable to that application.<p>
72
73 * If a certificate contains both a critical key usage field and a
74 * critical extended key usage field, then both fields MUST be
75 * processed independently and the certificate MUST only be used for a
76 * purpose consistent with both fields. If there is no purpose
77 * consistent with both fields, then the certificate MUST NOT be used
78 * for any purpose.<p>
79 *
80 * @since 1.4
