initHMAC
public abstract void initHMAC(SymmetricKey key) throws java.security.DigestException, java.security.InvalidKeyException
- Deprecated.
- Initializes an HMAC digest with the given symmetric key. This also has the effect of resetting the digest.
- Throws:
java.security.DigestException
- If this algorithm is not an HMAC algorithm.java.security.InvalidKeyException
- If the given key is not valid.
- Initializes an HMAC digest with the given symmetric key. This also has the effect of resetting the digest.
update
public void update(byte input) throws java.security.DigestException
- Deprecated.
- Updates the digest with a single byte of input.
- Throws:
java.security.DigestException
- Updates the digest with a single byte of input.
update
public abstract void update(byte[] input, int offset, int len) throws java.security.DigestException
- Deprecated.
- Updates the digest with a portion of an array.
- Parameters:
input
- An array from which to update the digest.offset
- The index in the array at which to start digesting.len
- The number of bytes to digest.- Throws:
java.security.DigestException
- If an error occurs while digesting.
- Updates the digest with a portion of an array.
update
public void update(byte[] input) throws java.security.DigestException
- Deprecated.
- Updates the digest with an array.
- Parameters:
input
- An array to feed to the digest.- Throws:
java.security.DigestException
- If an error occurs while digesting.
- Updates the digest with an array.
digest
public byte[] digest() throws java.security.DigestException
- Deprecated.
- Completes digestion.
- Parameters:
If
- an error occurs while digesting.- Returns:
- The, ahem, output of the digest operation.
- Throws:
java.security.DigestException
- Completes digestion.
digest
public abstract int digest(byte[] buf, int offset, int len) throws java.security.DigestException
- Deprecated.
- Completes digesting, storing the result into the provided array.
- Parameters:
buf
- The buffer in which to place the digest output.offset
- The offset in the buffer at which to store the output.len
- The amount of space available in the buffer for the digest output.- Returns:
- The number of bytes actually stored into buf.
- Throws:
java.security.DigestException
- If the provided space is too small for the digest, or an error occurs with the digest.
- Completes digesting, storing the result into the provided array.
digest
public byte[] digest(byte[] input) throws java.security.DigestException
- Deprecated.
- Provides final data to the digest, then completes it and returns the output.
- Parameters:
input
- The digest's last meal.- Returns:
- The completed digest.
- Throws:
java.security.DigestException
- If an error occurs while digesting.
- Provides final data to the digest, then completes it and returns the output.
reset
public abstract void reset() throws java.security.DigestException
- Deprecated.
- Resets this digest for further use. This clears all input and output streams. If this is an HMAC digest, the HMAC key is not cleared.
- Throws:
java.security.DigestException
- Resets this digest for further use. This clears all input and output streams. If this is an HMAC digest, the HMAC key is not cleared.
getAlgorithm
public abstract DigestAlgorithm getAlgorithm()
- Deprecated.
- Returns the algorithm that this digest uses.
