Cryptoinputstream
Web/** * Wraps a given InputStream with a CryptoInputStream. The size of the data * buffer required for the stream is specified by the * "mapreduce.job.encrypted-intermediate-data.buffer.kb" Job configuration * variable. * * If the value of 'length' is > -1, The InputStream is additionally * wrapped in a LimitInputStream. WebFileInputStream in = new FileInputStream (srcFile); CryptoInputStream encryptingStream = crypto.createEncryptingStream (masterKey, in, context); FileOutputStream out = new FileOutputStream (srcFile + ".encrypted" ); IOUtils.copy (encryptingStream, out); encryptingStream.close (); out.close (); // Decrypt the file.

WebCTR crypto stream has stream characteristic which is useful for implement features like random seek. The decryption is buffer based. The key points of the decryption are (1) calculating the counter and (2) padding through stream position: counter = base + pos/ (algorithm blocksize); padding = pos% (algorithm blocksize); Webpublic HdfsDataInputStream(org.apache.hadoop.crypto.CryptoInputStream in) Method Detail. getWrappedStream public InputStream getWrappedStream() Get a reference to the wrapped output stream. We always want to return the actual underlying InputStream, even when we're using a CryptoStream. e.g. in the delegated methods below.
