Enum Constant Detail

PLAIN

public static final PkceMethod PLAIN

The code challenge is identical to the code verifier.

S256

public static final PkceMethod S256

The code challenge is a SHA-256 hash of the code verifier.

NONE

public static final PkceMethod NONE

The OAuth 2.0 provider does not support PKCE at all.

Method Detail

values

public static PkceMethod[] 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 (PkceMethod c : PkceMethod.values())
    System.out.println(c);

Returns:

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

valueOf

public static PkceMethod 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

getCodeChallenge

public abstract String getCodeChallenge(String verifier)

Returns the code challenge to send on the authorization request.

Parameters:

verifier - the random code verifier associated with the request.

Returns:

the transformed code challenge.
