- Enum Constant Detail
  - NONE
```
public static final ClientAuthMethod NONE
```
    "none" (0).
    The Client does not authenticate itself at the Token Endpoint, either because it uses only the Implicit Flow (and so does not use the Token Endpoint) or because it is a Public Client with no Client Secret or other authentication mechanism.
  - CLIENT_SECRET_BASIC
```
public static final ClientAuthMethod CLIENT_SECRET_BASIC
```
    "client_secret_basic" (1).
    Clients that have received a client_secret value from the Authorization Server authenticate with the Authorization Server in accordance with Section 3.2.1 of OAuth 2.0 [RFC6749] using the HTTP Basic authentication scheme.
  - CLIENT_SECRET_POST
```
public static final ClientAuthMethod CLIENT_SECRET_POST
```
    "client_secret_post" (2).
    Clients that have received a client_secret value from the Authorization Server, authenticate with the Authorization Server in accordance with Section 3.2.1 of OAuth 2.0 [RFC6749] by including the Client Credentials in the request body.
  - CLIENT_SECRET_JWT
```
public static final ClientAuthMethod CLIENT_SECRET_JWT
```
    "client_secret_jwt" (3).
    Clients that have received a client_secret value from the Authorization Server create a JWT using an HMAC SHA algorithm, such as HMAC SHA-256. The HMAC (Hash-based Message Authentication Code) is calculated using the octets of the UTF-8 representation of the client_secret as the shared key.
    
    The Client authenticates in accordance with JSON Web Token (JWT) Profile for OAuth 2.0 Client Authentication and Authorization Grants [OAuth.JWT] and Assertion Framework for OAuth 2.0 Client Authentication and Authorization Grants [OAuth.Assertions].
  - PRIVATE_KEY_JWT
```
public static final ClientAuthMethod PRIVATE_KEY_JWT
```
    "private_key_jwt" (4).
    Clients that have registered a public key sign a JWT using that key. The Client authenticates in accordance with JSON Web Token (JWT) Profile for OAuth 2.0 Client Authentication and Authorization Grants [OAuth.JWT] and Assertion Framework for OAuth 2.0 Client Authentication and Authorization Grants [OAuth.Assertions].
  - TLS_CLIENT_AUTH
```
public static final ClientAuthMethod TLS_CLIENT_AUTH
```
    "tls_client_auth" (5).
    Clients authenticate with the Authorization Server using X.509 certificates as defined in "Mutual TLS Profiles for OAuth Clients".
    
    Since:
    
    2.7
  - SELF_SIGNED_TLS_CLIENT_AUTH
```
public static final ClientAuthMethod SELF_SIGNED_TLS_CLIENT_AUTH
```
    "self_signed_tls_client_auth" (6).
    Clients authenticate with the Authorization Server using self-signed certificates as defined in "Mutual TLS Profiles for OAuth Clients".
    
    Since:
    
    2.11
  - ATTEST_JWT_CLIENT_AUTH
```
public static final ClientAuthMethod ATTEST_JWT_CLIENT_AUTH
```
    "attest_jwt_client_auth" (7).
    OAuth 2.0 Attestation-Based Client Authentication.
    
    Since:
    
    3.74, Authlete 3.0

```
public static ClientAuthMethod[] 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 (ClientAuthMethod c : ClientAuthMethod.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ClientAuthMethod 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
  - getValue
```
public short getValue()
```
    Get the integer representation of this enum instance.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Enum<ClientAuthMethod>
  - getByValue
```
public static ClientAuthMethod getByValue(short value)
```
    Find an instance of this enum by a value.
    
    Parameters:
    
    value - The integer representation of the instance to find.
    
    Returns:
    
    An instance of this enum, or null if not found.
  - parse
```
public static ClientAuthMethod parse(String method)
```
    Convert String to ClientAuthMethod.
    
    Parameters:
    
    method - Client authentication method. For example, "client_secret_basic".
    
    Returns:
    
    ClientAuthMethod instance, or null.
  - toBits
```
public static int toBits(EnumSet<ClientAuthMethod> set)
```
  - toArray
```
public static ClientAuthMethod[] toArray(int bits)
```
  - toSet
```
public static EnumSet<ClientAuthMethod> toSet(int bits)
```
  - toSet
```
public static EnumSet<ClientAuthMethod> toSet(ClientAuthMethod[] array)
```
  - isSecretBased
```
public boolean isSecretBased()
```
    Check if this instance represents a client-secret-based client authentication method.
    
    Returns:
    
    true if this instance is either CLIENT_SECRET_BASIC or CLIENT_SECRET_POST.
    
    Since:
    
    2.47
  - isJwtBased
```
public boolean isJwtBased()
```
