Enum Constant Detail

digitalSignature

public static final KeyUsage digitalSignature

for SSL client certificates, S/MIME signing certificates, and object-signing certificates.

nonRepudiation

public static final KeyUsage nonRepudiation

for some S/MIME signing certificates and object-signing certificates.

keyEncipherment

public static final KeyUsage keyEncipherment

or SSL server certificates and S/MIME encryption certificates.

dataEncipherment

public static final KeyUsage dataEncipherment

when the subject's public key is used to encrypt user data instead of key material.

keyAgreement

public static final KeyUsage keyAgreement

when the subject's public key is used for key agreement.

keyCertSign

public static final KeyUsage keyCertSign

for all CA signing certificates.

cRLSign

public static final KeyUsage cRLSign

for CA signing certificates that are used to sign CRLs.

encipherOnly

public static final KeyUsage encipherOnly

if the public key is used only for enciphering data. If this bit is set, keyAgreement should also be set.

decipherOnly

public static final KeyUsage decipherOnly

if the public key is used only for deciphering data. If this bit is set, keyAgreement should also be set.

Field Detail

OID

public static final String OID

OID of KeyUsage.

Method Detail

values

public static KeyUsage[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (KeyUsage c : KeyUsage.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static KeyUsage valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

value

public int value()

Returns:

the integer value representing this usage.
