Method Detail

encrypt

byte[] encrypt(byte[] input)

Encrypts the input data using a symmetric cipher.

Parameters:

input - Plaintext data to encrypt.

Returns:

Ciphertext output.

encrypt

void encrypt(InputStream input,
             OutputStream output)

Encrypts the data from the input stream onto the output stream using a symmetric cipher.

The caller is responsible for providing and managing the streams (e.g. closing them when finished).

Parameters:

input - Input stream containing plaintext data to encrypt.

output - Output stream containing ciphertext produced by cipher in encryption mode.

decrypt

byte[] decrypt(byte[] input)

Decrypts the input data using a block cipher.

Parameters:

input - Ciphertext data to encrypt.

Returns:

Plaintext output.

decrypt

void decrypt(InputStream input,
             OutputStream output)

Decrypts the data from the input stream onto the output stream using a symmetric cipher.

The caller is responsible for providing and managing the streams (e.g. closing them when finished).

Parameters:

input - Input stream containing ciphertext data to decrypt.

output - Output stream containing plaintext produced by cipher in decryption mode.
