Method Details

doubleDigest

public static byte[] doubleDigest(byte[] input)

See doubleDigest(byte[], int, int).

Parameters:

input - A byte array to double digest.

Returns:

The SHA-256 hash of the SHA-256 hash of the given input.

doubleDigest

public static byte[] doubleDigest(byte[] input,
 int offset,
 int length)

Calculates the SHA-256 hash of the given byte range, and then hashes the resulting hash again. This is standard procedure in XRPL. The resulting hash is in big endian form.

Parameters:

input - A byte array to double digest.

offset - The beginning index of the input to digest.

length - The length of the input to digest.

Returns:

The SHA-256 hash of the SHA-256 hash of the given input.
