All Implemented Interfaces:

Serializable, Comparable<SignatureHashAlgorithms>

public enum SignatureHashAlgorithms
extends Enum<SignatureHashAlgorithms>

Hashing algorithms available for the PKCS#7/CMS signature digest (the "Hash Algorithm" Adobe Reader shows under Signature Details). SHA-256 is the modern default; SHA-1 remains selectable only for compatibility with legacy validators and is cryptographically weak.

Enum Constant Detail

SHA256

public static final SignatureHashAlgorithms SHA256

SHA-256 algorithm (default, recommended).

SHA384

public static final SignatureHashAlgorithms SHA384

SHA-384 algorithm.

SHA512

public static final SignatureHashAlgorithms SHA512

SHA-512 algorithm.

SHA1

public static final SignatureHashAlgorithms SHA1

SHA-1 algorithm (legacy, cryptographically weak. Avoid for new signatures).

Method Detail

values

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

Returns:

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

valueOf

public static SignatureHashAlgorithms 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 int getValue()
