public interface AEADBlockCipher
A block cipher mode that includes authenticated encryption with a streaming mode and optional associated data.
AEADParameters| Method Summary | |
|---|---|
int |
doFinal(byte[] out,
int outOff)
Finish the operation either appending or verifying the MAC at the end of the data. |

Return the name of the algorithm. |
byte[] |
getMac()
Return the value of the MAC associated with the last stream processed. |
int |
getOutputSize(int len)
return the size of the output buffer required for a processBytes plus a doFinal with an input of len bytes. |
BlockCipher |
getUnderlyingCipher()

return the size of the output buffer required for a processBytes an input of len bytes. |
void |
init(boolean forEncryption,
CipherParameters params)
initialise the underlying cipher. |
int |
processByte(byte in,
byte[] out,
int outOff)
encrypt/decrypt a single byte. |
int |
processBytes(byte[] in,
int inOff,
int len,

void init(boolean forEncryption,
CipherParameters params)
throws java.lang.IllegalArgumentException
forEncryption - true if we are setting up for encryption, false otherwise.params - the necessary parameters for the underlying cipher to be initialised.
java.lang.IllegalArgumentException - if the params argument is inappropriate.java.lang.String getAlgorithmName()
BlockCipher getUnderlyingCipher()
int processByte(byte in,
byte[] out,
int outOff)
throws DataLengthException
in - the byte to be processed.out - the output buffer the processed byte goes into.outOff - the offset into the output byte array the processed data starts at.
DataLengthException - if the output buffer is too small.
int processBytes(byte[] in,
int inOff,
int len,
byte[] out,
int outOff)
throws DataLengthException
in - the input byte array.inOff - the offset into the in array where the data to be processed starts.len - the number of bytes to be processed.out - the output buffer the processed bytes go into.outOff - the offset into the output byte array the processed data starts at.
DataLengthException - if the output buffer is too small.
int doFinal(byte[] out,
int outOff)
throws java.lang.IllegalStateException,
InvalidCipherTextException
out - space for any resulting output data.outOff - offset into out to start copying the data at.
java.lang.IllegalStateException - if the cipher is in an inappropriate state.
InvalidCipherTextException - if the MAC fails to match.byte[] getMac()
int getUpdateOutputSize(int len)
len - the length of the input.
int getOutputSize(int len)
len - the length of the input.
void reset()
