X509Certificate.KeyUsage (Oracle Java ME Embedded)

java.lang.Object
- java.lang.Enum<X509Certificate.KeyUsage>
- - com.oracle.crypto.cert.X509Certificate.KeyUsage

All Implemented Interfaces:

java.lang.Comparable<X509Certificate.KeyUsage>

Enclosing interface:

X509Certificate
```
public static enum X509Certificate.KeyUsage
extends java.lang.Enum<X509Certificate.KeyUsage>
```
The key usage extension defines the purpose (e.g., encipherment, signature, certificate signing)of the key contained in the certificate.

- Enum Constant Detail
  - DIGITAL_SIGNATURE
```
public static final X509Certificate.KeyUsage DIGITAL_SIGNATURE
```
    Digital Signature. The digitalSignature bit is asserted when the subject public key is used for verifying digital signatures, other than signatures on certificates (bit 5) and CRLs (bit 6), such as those used in an entity authentication service, a data origin authentication service, and/or an integrity service.
  - NON_REPUDIATION
```
public static final X509Certificate.KeyUsage NON_REPUDIATION
```
    Non Repudiation. The nonRepudiation bit is asserted when the subject public key is used to verify digital signatures, other than signatures on certificates (bit 5) and CRLs (bit 6), used to provide a non-repudiation service that protects against the signing entity falsely denying some action.
  - KEY_ENCIPHERMENT
```
public static final X509Certificate.KeyUsage KEY_ENCIPHERMENT
```
    Key Encipherment. The keyEncipherment bit is asserted when the subject public key is used for enciphering private or secret keys, i.e., for key transport.
  - DATA_ENCIPHERMENT
```
public static final X509Certificate.KeyUsage DATA_ENCIPHERMENT
```
    Data Encipherment. The dataEncipherment bit is asserted when the subject public key is used for directly enciphering raw user data without the use of an intermediate symmetric cipher.
  - KEY_AGREEMENT
```
public static final X509Certificate.KeyUsage KEY_AGREEMENT
```
    Key Agreement. The keyAgreement bit is asserted when the subject public key is used for key agreement.
  - KEY_CERT_SIGN
```
public static final X509Certificate.KeyUsage KEY_CERT_SIGN
```
    Certificate Sign. The keyCertSign bit is asserted when the subject public key is used for verifying signatures on public key certificates.
  - CRL_SIGN
```
public static final X509Certificate.KeyUsage CRL_SIGN
```
    CRL Sign. The cRLSign bit is asserted when the subject public key is used for verifying signatures on certificate revocation lists.
  - ENCIPHER_ONLY
```
public static final X509Certificate.KeyUsage ENCIPHER_ONLY
```
    Encipher Only. The meaning of the encipherOnly bit is undefined in the absence of the keyAgreement bit. When the encipherOnly bit is asserted and the keyAgreement bit is also set, the subject public key may be used only for enciphering data while performing key agreement.
  - DECIPHER_ONLY
```
public static final X509Certificate.KeyUsage DECIPHER_ONLY
```
    Decipher Only. The meaning of the decipherOnly bit is undefined in the absence of the keyAgreement bit. When the decipherOnly bit is asserted and the keyAgreement bit is also set, the subject public key may be used only for deciphering data while performing key agreement.
- Method Detail
  - values
```
public static X509Certificate.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 (X509Certificate.KeyUsage c : X509Certificate.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 X509Certificate.KeyUsage valueOf(java.lang.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:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
