Method Summary

Modifier and Type	Method	Description
void	close()	Destroys the cipher, preventing future use.
int	decrypt(byte[] encryptedData, int inputOffset, int length, byte[] destination, int destinationOffset)	Decrypts the contents of the input buffer into the destination buffer, returning the number of bytes written into the destination buffer
int	decryptedMaxLength(int encryptedLength)	Calculates the required buffer size to decrypt data with the given encrypted length
int	encrypt(byte[] data, int inputOffset, int length, byte[] destination, int destinationOffset)	Encrypts the contents of the input buffer into the destination buffer returning the number of bytes written into the destination buffer
int	encryptedMaxLength(int inputLength)	Calculates the maximum required buffer size to encrypt input data with the given length

Method Details

encryptedMaxLength

int encryptedMaxLength(int inputLength)

Calculates the maximum required buffer size to encrypt input data with the given length

encrypt

int encrypt(byte[] data,
 int inputOffset,
 int length,
 byte[] destination,
 int destinationOffset)

Encrypts the contents of the input buffer into the destination buffer returning the number of bytes written into the destination buffer

Returns:

The length of the encrypted content in the destination buffer

decryptedMaxLength

int decryptedMaxLength(int encryptedLength)

Calculates the required buffer size to decrypt data with the given encrypted length

decrypt

int decrypt(byte[] encryptedData,
 int inputOffset,
 int length,
 byte[] destination,
 int destinationOffset)

Decrypts the contents of the input buffer into the destination buffer, returning the number of bytes written into the destination buffer

Returns:

The length of the decrypted content in destination buffer

close

void close()

Destroys the cipher, preventing future use. Implementations should allow this to be called multiple times without failing.
