| Method Summary | |
| public void | clear()
| | public byte[] | sign()
| | public void | update(byte[] b, int offset, int length)
| | public void | update(byte[] b)
| | public boolean | verify(byte[] signature)
|
| HMAC | | public HMAC(MessageDigest digest, byte[] key)(Code) | | Creates a new HMAC instance
Parameters:
digest - The message digest object.
Parameters:
key - The secret key |
| HMAC | | public HMAC(String digestName, byte[] key)(Code) | | Creates a new HMAC instance
Parameters:
digestName - The name of the message digest function.
Parameters:
key - The secret key. |
| clear | | public void clear()(Code) | | Resets the HMAC object for further use
|
| sign | | public byte[] sign()(Code) | | Signs the data (computes the secure hash)
An array with the signature |
| update | | public void update(byte[] b, int offset, int length)(Code) | | Adds data to the current hash
Parameters:
b - The data
Parameters:
offset - The index at which to start adding to the hash
Parameters:
length - The number of bytes to hash |
| update | | public void update(byte[] b)(Code) | | Adds data to the current hash
Parameters:
b - The data |
| verify | | public boolean verify(byte[] signature)(Code) | | Verifies the data (computes the secure hash and compares it to the input)
Parameters:
signature - The signature to compare against true if the signature matched, false otherwise |
