Using Python I want to randomly rearrange sections of a string based on a given key. I also want to restore the original string with the same key: def rearrange(key, data): pass def restore(key, rearranged_data): pass Efficiency is not important. Any ideas? Edit: can assume key is hashable, but may be multiple types defin...
I'm trying to have Java server and C++ clients communicate over TCP under the following conditions: text mode, and binary/encrypted mode. My problem is over the eof indicator for end of stream that DataInputStream's read(byte []) uses to return with -1. If I send binary data, what's to prevent a random byte sequence happening to repres...
I'm working with a listview control which saves the data using AES encryption to a file. I need to keep the data of every item in listview in std::list class of std::string. should I just keep the data encrypted in std::list and decrypt to a local variable when its needed? or is it enough to keep it encrypted in file only? ...

Hi all, My system enables users to save their work as a draft. I'd like to encrypt the data before I persist it. I was working on this - AESKey k = new AESKey(); AESEncryptorEngine a = new AESEncryptorEngine(k); a.encrypt(byte[] data_input, int input_offset, byte[] data_output, byte[] output_offset); I however need to persist an obje...
Is there a way in PHP 5.3 to get crypt() blowfish (salt starting with $2a$) results identical to those generated by PHP 5.2? In 5.3, Zend implements all encryption algorithms internally, thus producing different results. Also, in 5.3, blowfish needs a cost parameter. Basically, is there a way to call whatever system mechanisms were used...
I need to encrypt and send data over TCP (from a few 100 bytes to a few 100 megabytes per message) in chunks from Java to a C++ program, and need to send the size of the data ahead of time so the recipient knows when to stop reading the current message and process it, then wait for the next message (the connection stays open so there's n...
I have heard that the only purpose of a salt is to prevent rainbow table attacks, but surely it must have more value than this? Would it not prevent a dictionary-based attack too? And what about brute-forcing, would a salt be of any use there? And could you explain why, please? Second, suppose I had an algorithm that took the microtime,...
