com.sun.midp.crypto.SHA
| Constructor Summary | |
| | SHA()
Create SHA digest object. |
| Method Summary | |
| public Object | clone()
Clones the MessageDigest object. | | public int | digest(byte[] buf, int offset, int len)
Completes the hash computation by performing final operations
such as padding. | | public String | getAlgorithm()
Gets the message digest algorithm. | | public int | getDigestLength()
Gets the length (in bytes) of the hash. | | public void | reset()
Resets the MessageDigest to the initial state for further use. | | public void | update(byte[] inBuf, int inOff, int inLen)
Accumulates a hash of the input data. |
| SHA | | SHA()(Code) | | Create SHA digest object.
|
| clone | | public Object clone()(Code) | | Clones the MessageDigest object.
a clone of this object |
| digest | | public int digest(byte[] buf, int offset, int len) throws DigestException(Code) | | Completes the hash computation by performing final operations
such as padding. The digest is reset after this call is made.
Parameters:
buf - output buffer for the computed digest
Parameters:
offset - offset into the output buffer to begin storing the digest
Parameters:
len - number of bytes within buf allotted for the digest the number of bytes placed into buf
exception:
DigestException - if an error occurs. |
| getAlgorithm | | public String getAlgorithm()(Code) | | Gets the message digest algorithm.
algorithm implemented by this MessageDigest object |
| getDigestLength | | public int getDigestLength()(Code) | | Gets the length (in bytes) of the hash.
byte-length of the hash produced by this object |
| reset | | public void reset()(Code) | | Resets the MessageDigest to the initial state for further use.
|
| update | | public void update(byte[] inBuf, int inOff, int inLen)(Code) | | Accumulates a hash of the input data. This method is useful when
the input data to be hashed is not available in one byte array.
Parameters:
inBuf - input buffer of data to be hashed
Parameters:
inOff - offset within inBuf where input data begins
Parameters:
inLen - length (in bytes) of data to be hashed
