Method Detail

isUnlimitedStrength

public static boolean isUnlimitedStrength()

Checks if unlimited cryptographic strength is supported. If not download the appropriate jurisdiction policy files for your Java edition:

JCE Unlimited Strength Jurisdiction Policy Files for Java 7

JCE Unlimited Strength Jurisdiction Policy Files for Java 8

Returns:

true if unlimited cryptographic strength is supported, false if not.

isSupported

public static boolean isSupported(JWSAlgorithm alg)

Checks if the specified JWS algorithm is supported by the default system JCA provider(s).

Parameters:

alg - The JWS algorithm. Must not be null.

Returns:

true if the JWS algorithm is supported, else false.

isSupported

public static boolean isSupported(JWSAlgorithm alg,
                                  Provider provider)

Checks if a JWS algorithm is supported by the the specified JCA provider.

Parameters:

alg - The JWS algorithm. Must not be null.

provider - The JCA provider. Must not be null.

Returns:

true if the JWS algorithm is supported, else false.

isSupported

public static boolean isSupported(JWEAlgorithm alg)
