Method Detail

getOutputSize

int getOutputSize(int len)

Gets the size of the output buffer required to hold the output of an input buffer of the given size.

Parameters:

len - Length of input buffer.

Returns:

Size of output buffer.

doFinal

int doFinal(byte[] out,
            int outOff)
     throws CryptoException

Finish the encryption/decryption operation (e.g. apply padding).

Parameters:

out - Output buffer to receive final processing output.

outOff - Offset into output buffer where processed data should start.

Returns:

Number of bytes written to output buffer.

Throws:

CryptoException - on underlying cipher finalization errors.
