Description copied from interface: SpillCipher

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

Specified by:

encryptedMaxLength in interface SpillCipher

decryptedMaxLength

public int decryptedMaxLength(int encryptedLength)

Description copied from interface: SpillCipher

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

Specified by:

decryptedMaxLength in interface SpillCipher

encrypt

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

Description copied from interface: SpillCipher

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

Specified by:

encrypt in interface SpillCipher

Returns:

The length of the encrypted content in the destination buffer

decrypt

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

Description copied from interface: SpillCipher

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

Specified by:

decrypt in interface SpillCipher

Returns:

The length of the decrypted content in destination buffer

close

public void close()

Description copied from interface: SpillCipher

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

Specified by:

close in interface AutoCloseable

Specified by:

close in interface SpillCipher

toString

public String toString()

Overrides:

toString in class Object
