35/**
36 * The reasonCode is a non-critical CRL entry extension that identifies
37 * the reason for the certificate revocation. CAs are strongly
38 * encouraged to include reason codes in CRL entries; however, the
39 * reason code CRL entry extension should be absent instead of using the
40 * unspecified (0) reasonCode value.
41 * <p>The ASN.1 syntax for this is:
42 * <pre>
43 * id-ce-cRLReason OBJECT IDENTIFIER ::= { id-ce 21 }
44 *
45 * -- reasonCode ::= { CRLReason }
46 *
47 * CRLReason ::= ENUMERATED {
48 * unspecified (0),
49 * keyCompromise (1),
50 * cACompromise (2),
51 * affiliationChanged (3),
52 * superseded (4),
53 * cessationOfOperation (5),
54 * certificateHold (6),
55 * removeFromCRL (8),
56 * privilegeWithdrawn (9),
57 * aACompromise (10) }
