All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<CertificateBuilder.ExtendedKeyUsage>

Enclosing class:

CertificateBuilder
```
public static enum CertificateBuilder.ExtendedKeyUsage
extends java.lang.Enum<CertificateBuilder.ExtendedKeyUsage>
```
The extended key usage field specify what the certificate and key is allowed to be used for.
A certificate can have many key usages. For instance, some certificates support both client and server usage for TLS connections.
The key usage must be checked by the opposing peer receiving the certificate, and reject certificates that do not permit the given usage.
For instance, if a TLS client connects to a server that presents a certificate without the server-authentication usage, then the client must reject the server certificate as invalid.

```
public static CertificateBuilder.ExtendedKeyUsage[] 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.ExtendedKeyUsage c : CertificateBuilder.ExtendedKeyUsage.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.ExtendedKeyUsage 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
  - getOid
