Method Detail

values

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

Returns:

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

valueOf

public static SignatureAndHashAlgorithm.SignatureAlgorithm 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

getAlgorithmByCode

public static SignatureAndHashAlgorithm.SignatureAlgorithm getAlgorithmByCode(int code)

Gets an algorithm by its code.

Parameters:

code - The algorithm's code.

Returns:

The algorithm or null if no algorithm is defined for the given code by RFC 5246, Appendix A.4.1, or RFC 8422, Section 5.1.3.

getCode

public int getCode()

Gets the code of this algorithm as defined by RFC 5246, Appendix A.4.1, or RFC 8422, Section 5.1.3.

Returns:

The code.

isEcdsaCompatible

public boolean isEcdsaCompatible()

Gets ECDSA compatibility.

Returns:

true, for ECDSA compatible signature, false, otherwise.

Since:

2.4
