Enum Constant Detail

SHA256

public static final HashFunction SHA256

Use Java implementation of SHA256 (code 2)

SHA3

public static final HashFunction SHA3

Use Bouncy Castle implementation of SHA3 (code 3). As of Bouncy Castle 1.53, this has been renamed to Keccak.

SCRYPT

public static final HashFunction SCRYPT

Use Java implementation of Scrypt

Keccak25

public static final HashFunction Keccak25

Use proprietary NXT implementation of Keccak with 25 rounds (code 25)

RIPEMD160

public static final HashFunction RIPEMD160

RIPEMD160_SHA256

public static final HashFunction RIPEMD160_SHA256

Method Detail

values

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

Returns:

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

valueOf

public static HashFunction valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getHashFunction

public static HashFunction getHashFunction(byte id)

getId

public byte getId()

hash

public abstract byte[] hash(byte[] input)
