SHA1Hasher

• java.lang.Object

Fields Summary
private final SHA1	sha1

Constructors Summary
public SHA1Hasher() Create a new SHA1Hasher instance sha1 = new SHA1();

Methods Summary
public byte[]	calculateHash(byte[] bytes) Calculate the SHA-1 hash for the given bytes. param bytes data to hash return 20-byte hash ByteBuffer buff = ByteBuffer.wrap( bytes ); return calculateHash( buff );
public byte[]	calculateHash(java.nio.ByteBuffer buffer) Calculate the SHA-1 hash for the given buffer. param buffer data to hash return 20-byte hash sha1.reset(); return sha1.digest( buffer );
public byte[]	getDigest() Finish the hash calculation. return 20-byte hash return sha1.digest();
public void	reset() Resets the hash calculation. sha1.reset();
public void	restoreHashState() Restore the hasher state from previous save. sha1.restoreState();
public void	saveHashState() Save the current hasher state for later resuming. sha1.saveState();
public void	update(byte[] data) Start or continue a hash calculation with the given data. param data input update( ByteBuffer.wrap( data ));
public void	update(byte[] data, int pos, int len) Start or continue a hash calculation with the given data, starting at the given position, for the given length. param data input param pos start position param len length update( ByteBuffer.wrap( data, pos, len ));
public void	update(java.nio.ByteBuffer buffer) Start or continue a hash calculation with the given data. param buffer data input sha1.update( buffer );
