Method Detail

update

public byte[] update(byte[] input,
                     int inOff,
                     int inLen)

Continue a multiple-part encryption or decryption operation.

Specified by:

update in class AsymmetricHybridCipher

Parameters:

input - byte array containing the next part of the input

inOff - index in the array where the input starts

inLen - length of the input

Returns:

the processed byte array.

doFinal

public byte[] doFinal(byte[] input,
                      int inOff,

               throws javax.crypto.BadPaddingException

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

Specified by:

doFinal in class AsymmetricHybridCipher

Parameters:

input - the input buffer

inOff - the offset in input where the input starts

inLen - the input length

Returns:

the new buffer with the result

Throws:

javax.crypto.BadPaddingException - if this cipher is in decryption mode, and (un)padding has been requested, but the decrypted data is not bounded by the appropriate padding bytes
