| Field Summary | |
| MD5State | finals
If Final() has been called, finals is set to the current finals
state. | | static byte | padding
| | MD5State | state
|
| Method Summary | |
| public synchronized byte[] | Final()
Returns array of bytes (16 bytes) representing hash as of the
current state of this object. | | public synchronized void | Init()
| | public void | Update(MD5State stat, byte buffer, int offset, int length)
| | public void | Update(byte buffer, int offset, int length)
| | public void | Update(byte buffer, int length)
| | public void | Update(byte buffer)
| | public void | Update(byte b)
| | public void | Update(String s)
Update buffer with given string. | | public void | Update(int i)
| | public static String | asHex(byte hash)
Turns array of bytes into string representing each byte as
unsigned hex number. | | public String | asHex()
|
| finals | | MD5State finals(Code) | | If Final() has been called, finals is set to the current finals
state. Any Update() causes this to be set to null.
|
| padding | | static byte padding(Code) | | Padding for Final()
|
| state | | MD5State state(Code) | | MD5 state
|
| MD5 | | public MD5()(Code) | | Class constructor
|
| MD5 | | public MD5(Object ob)(Code) | | Initialize class, and update hash with ob.toString()
Parameters:
ob - Object, ob.toString() is used to update hashafter initialization |
| Final | | public synchronized byte[] Final()(Code) | | Returns array of bytes (16 bytes) representing hash as of the
current state of this object. Note: getting a hash does not
invalidate the hash object, it only creates a copy of the real
state which is finalized.
Array of 16 bytes, the hash of all updated bytes |
| Init | | public synchronized void Init()(Code) | | Initialize MD5 internal state (object can be reused just by
calling Init() after every Final()
|
| Update | | public void Update(MD5State stat, byte buffer, int offset, int length)(Code) | | Updates hash with the bytebuffer given (using at maximum length bytes from
that buffer)
Parameters:
state - Which state is updated
Parameters:
buffer - Array of bytes to be hashed
Parameters:
offset - Offset to buffer array
Parameters:
length - Use at maximum `length' bytes (absolutemaximum is buffer.length) |
| Update | | public void Update(byte buffer, int offset, int length)(Code) | | Plain update, updates this object
|
| Update | | public void Update(byte buffer, int length)(Code) | | |
| Update | | public void Update(byte buffer)(Code) | | Updates hash with given array of bytes
Parameters:
buffer - Array of bytes to use for updating the hash |
| Update | | public void Update(byte b)(Code) | | Updates hash with a single byte
Parameters:
b - Single byte to update the hash |
| Update | | public void Update(String s)(Code) | | Update buffer with given string.
Parameters:
s - String to be update to hash (is used ass.getBytes()) |
| Update | | public void Update(int i)(Code) | | Update buffer with a single integer (only & 0xff part is used,
as a byte)
Parameters:
i - Integer value, which is then converted tobyte as i & 0xff |
| asHex | | public static String asHex(byte hash)(Code) | | Turns array of bytes into string representing each byte as
unsigned hex number.
Parameters:
hash - Array of bytes to convert to hex-string Generated hex string |
| asHex | | public String asHex()(Code) | | Returns 32-character hex representation of this objects hash
String of this object's hash |
