public class SHA1InterleaveDigest extends java.lang.Object implements Digest, Memoable
The complete input is buffered until doFinal(byte[], int) is called: leading
zero bytes are removed, a further leading byte is removed if the remaining length is odd,
the even-numbered and odd-numbered bytes are then hashed separately with SHA-1, and the
two hashes are interleaved to form the 40 byte result.
