Constructor Detail

JrpcgenSHA

public JrpcgenSHA()

Create a new SHA-1 hashing object.

Method Detail

update

public void update(byte b)

Update the hash using a single byte (8 bits).

Parameters:

b - Byte to hash.

update

public void update(short s)

Update the hash using a short integer (16 bits).

Parameters:

s - Short integer to hash.

update

public void update(int i)

Update the hash using an integer (32 bits).

Parameters:

i - Integer to hash.

update

public void update(String s)

Update the hash using a string.

Parameters:

s - String to hash.

reset

public void reset()

Reset the hashing engine to start hashing another set of innocent bytes.

getDigest

public byte[] getDigest()

Retrieve the digest (that is, informally spoken, the "hash value").

Returns:

digest as a series of 20 bytes (80 bits).

getHash

public long getHash()

Return first 64 bits of hash digest for use as a serialization UID, etc.

Returns:

hash digest with only 64 bit size.
