Method Detail

values

public static SHA2[] 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 (SHA2 c : SHA2.values())
    System.out.println(c);

Returns:

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

valueOf

public static SHA2 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

sha256

public static net.openhft.chronicle.bytes.BytesStore sha256(net.openhft.chronicle.bytes.BytesStore message)

Generate sha256 hash for a given message

Parameters:

message - - the message to hash

Returns:

- the sha256 hash

sha256

Generate hash for a given message

Parameters:

result - - the BytesStore to hold the result

message - - the message to hash

Returns:

- the sha256 hash

appendSha256

public static void appendSha256(net.openhft.chronicle.bytes.Bytes<?> hash256,
                                net.openhft.chronicle.bytes.BytesStore<?,?> message)

Append the sha256 hash of a message to a given Bytes handle

Parameters:

hash256 - - the Bytes handle onto which the sha256 hash is appended

message - - the message to hash

sha512

public static net.openhft.chronicle.bytes.BytesStore sha512(net.openhft.chronicle.bytes.BytesStore message)

Generate sha512 hash for a given message

Parameters:

message - - the message to hash

Returns:

- the sha256 hash
