twocrypt(2c)是一个 PoC工具，用于超狂妄者。它把两个文件加密成一个。不同的口令可以用于解译不同的变量。输出不能从单个加密文件中识别出来，并且这个工具使用一种合法的算法，这种算法本身并不意味着要隐藏任何信息。-twocrypt (2c) is a PoC tool, uses in the ultra arrogance. It encrypts two documents. The different password may use in the solution to translate the different variable. The output cannot from individually encrypt in the document to distinguish, and this tool uses one legitimate algorithm, this algorithm itself certainly did not mean must hide any information.

AML EFFICIENT APPROXIMATE MEMBERSHIP LOCALIZATION WITHIN A WEB-BASED JOIN FRAMEWORK ABSTRACT: In this paper, we propose a new type of Dictionary-based Entity Recognition Problem, named Approximate Membership Localization (AML). The popular Approximate Membership Extraction (AME) provides a full coverage to the true matched substrings from a given document, but many redundancies cause a low efficiency of the AME process and deteriorate the performance of real-world applications using the extracted substrings. The AML problem targets at locating non overlapped substrings which is a better approximation to the true matched substrings without generating overlapped redundancies. In order to perform AML efficiently, we propose the optimized algorithm P-Prune that prunes a large part of overlapped redundant matched substrings before generating them.
