Method Detail

initEncryptMode

void initEncryptMode(Key key)

Generates a Cipher object that implements the specified transformation, initializes cipher vector and initializes cipher to encryption mode with a key and a set of algorithm parameters.

Parameters:

key - the encryption key

Throws:

HDIVException - if there is an initialization error.

initDecryptMode

void initDecryptMode(Key key)

Generates a Cipher object that implements the specified transformation, initializes cipher vector and initializes cipher to decryption mode with a key and a set of algorithm parameters.

Parameters:

key - the encryption key

Throws:

HDIVException - if there is an initialization error.

encrypt

byte[] encrypt(byte[] data)

Encrypts data in a single-part operation, or finishes a multiple-part operation. The data is encrypted depending on how this cipher was initialized.

The bytes in the input buffer, and any input bytes that may have been buffered during a previous update operation, are processed, with padding (if requested) being applied. The result is stored in a new buffer.

if any exception is thrown, this cipher object may need to be reset before it can be used again.

Parameters:

data - The input buffer to encrypt

Returns:

The new buffer with the result

decrypt

byte[] decrypt(byte[] data)

Decrypts data in a single-part operation, or finishes a multiple-part operation. The data is decrypted depending on how this cipher was initialized.

The bytes in the input buffer, and any input bytes that may have been buffered during a previous update operation, are processed, with padding (if requested) being applied. The result is stored in a new buffer.

if any exception is thrown, this cipher object may need to be reset before it can be used again.

Parameters:

data - The input buffer to decrypt

Returns:

The new buffer with the result
