Enum CertificateBuilder.KeyUsage

java.lang.Object

java.lang.Enum<CertificateBuilder.KeyUsage>

io.netty.pkitesting.CertificateBuilder.KeyUsage

All Implemented Interfaces:

Serializable, Comparable<CertificateBuilder.KeyUsage>

Enclosing class:

CertificateBuilder

public static enum CertificateBuilder.KeyUsage
extends Enum<CertificateBuilder.KeyUsage>

The key usage field specify what the certificate and key is allowed to be used for.

These key usages are specified by the X.509 standard, and some of them are deprecated.

See the CertificateBuilder.ExtendedKeyUsage for other commonly used key usage extensions.

See ITU-T X.509 (10/2019) section 9.2.2.3 for the precise meaning of these usages.

Enum Constant Summary

Enum Constants

Enum Constant	Description
contentCommitment	This key usage is deprecated by X.509, and commitment may instead be derived from the actual use of the keys.
cRLSign	For verifying the Certificate Authority's signature on a Certificate Revocation List.
dataEncipherment	For enciphering user data, but not keys or security information.
decipherOnly	For use with keyAgreement to limit the key to deciphering only.
digitalSignature	For verifying digital signatures, for entity authentication, for entity authentication, or for integrity verification.
encipherOnly	For use with keyAgreement to limit the key to enciphering only.
keyAgreement	For use in public key agreement.
keyCertSign	For verifying the Certificate Authority's signature on a public-key certificate.
keyEncipherment	For enciphering keys or other security information.

Method Summary

Modifier and Type	Method	Description
static CertificateBuilder.KeyUsage	valueOf(String name)	Returns the enum constant of this type with the specified name.
static CertificateBuilder.KeyUsage[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

digitalSignature

public static final CertificateBuilder.KeyUsage digitalSignature

For verifying digital signatures, for entity authentication, for entity authentication, or for integrity verification.

contentCommitment

public static final CertificateBuilder.KeyUsage contentCommitment

This key usage is deprecated by X.509, and commitment may instead be derived from the actual use of the keys.

For verifying digital signatures that imply the signer has "committed" to the content being signed. This does not imply any specific policy or review on part of the signer, however.

keyEncipherment

public static final CertificateBuilder.KeyUsage keyEncipherment

For enciphering keys or other security information.

dataEncipherment

public static final CertificateBuilder.KeyUsage dataEncipherment

For enciphering user data, but not keys or security information.

keyAgreement

public static final CertificateBuilder.KeyUsage keyAgreement

For use in public key agreement.

keyCertSign

public static final CertificateBuilder.KeyUsage keyCertSign

For verifying the Certificate Authority's signature on a public-key certificate.

This implies digitalSignature and contentCommitment, so they do not need to be specified separately.

cRLSign

public static final CertificateBuilder.KeyUsage cRLSign

For verifying the Certificate Authority's signature on a Certificate Revocation List.

This implies digitalSignature and contentCommitment, so they do not need to be specified separately.

encipherOnly

public static final CertificateBuilder.KeyUsage encipherOnly

For use with keyAgreement to limit the key to enciphering only.

The meaning of this without the keyAgreement bit set is unspecified.

decipherOnly

public static final CertificateBuilder.KeyUsage decipherOnly

For use with keyAgreement to limit the key to deciphering only.

The meaning of this without the keyAgreement bit set is unspecified.

Method Detail

values

public static CertificateBuilder.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 (CertificateBuilder.KeyUsage c : CertificateBuilder.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 CertificateBuilder.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
