Method Detail

decryptFirstBytes

public byte[] decryptFirstBytes(byte[] bits)

Description copied from class: DecryptionTool

Decrypts the beginning of the file and returns its clear-text binary representation.

Specified by:

decryptFirstBytes in class DecryptionTool

Parameters:

bits - the first chunk of data of the datafile. The input byte array can contain zero-bytes padding (eg. case of DEFLATE compression in Zip files, the decompressed data can be smaller than the source chunk). The implementation of the method should discard the padding (all zero bytes at the end of the array).

Returns:

Decrypted binary data or the input byte array if Tool is not compatible with this input.

decryptInputStream

public java.io.InputStream decryptInputStream(java.io.InputStream is)

Description copied from class: DecryptionTool

Wraps the source InputStream into deciphering input stream

Specified by:

decryptInputStream in class DecryptionTool

Parameters:

is - InputStream created by ByteVec (H2O-specific behavior is expected!)

Returns:

InputStream of decrypted data
