fwknop stands for "Firewall Knock Operator" and is an upcoming piece of software that will be released at the DEFCON 12 conference in July, 2004 in Las Vegas. fwknop implements network access controls (via iptables) based on a flexible port knocking mini-language, but with a twist it combines port knocking and passive operating system fingerprinting to make it possible to do things like only allow, say, Linux-2.4/2.6 systems to connect to your SSH daemon. fwknop supports shared, multi-protocol port knock sequences along with both relative and absolute timeouts, and coded port knock sequences encrypted with the Rijndael block cipher.

對稱/分組密碼一般分為流加密(如OFB、CFB等)和塊加密(如ECB、CBC等)。對于流加密,需要將分組密碼轉(zhuǎn)化為流模式工作。對于塊加密(或稱分組加密),如果要加密超過塊大小的數(shù)據(jù),就需要涉及填充和鏈加密模式,文中提到的ECB和CBC等就是指鏈加密模式。 本文將要介紹了AES對稱加密/分組加密/流密碼及其ECB、CBC、CFB、OFB和CTR五種對稱加密模式。

This work briefly explains common cryptosystems and details two most popular private-key ciphers: DES ,which is probably the most widely used, and AES, which is intended to replace DES.

Free open-source disk encryption software for Windows Vista/XP, Mac OS X, and Linux Main Features: * Creates a virtual encrypted disk within a file and mounts it as a real disk. * Encrypts an entire partition or storage device such as USB flash drive or hard drive. * Encrypts a partition or drive where Windows is installed (pre-boot authentication). * Encryption is automatic, real-time (on-the-fly) and transparent. * Provides two levels of plausible deniability, in case an adversary forces you to reveal the password: 1) Hidden volume (steganography) and hidden operating system. 2) No TrueCrypt volume can be identified (volumes cannot be distinguished from random data). * Encryption algorithms: AES-256, Serpent, and Twofish. Mode of operation: XTS. Further information regarding features of the software may be found in the:http://www.truecrypt.org/

1、更正了原來的1.0版本的所有內(nèi)存泄漏問題。 2、使用了文件讀寫的緩沖技術(shù),對加密與解密在速度上都有一定的加快。 3、使用了進度條來顯示加密與解密的進度,使其過程更加生動,不單調(diào)。 4、使用了多線程技術(shù),這對于有多處理機的計算機來說,速度有一定的提高。 5、使用了與原始AES加密/解密算法中對狀態(tài)數(shù)組按列處理等價的按行來處理數(shù) 據(jù)(當然在相應(yīng)的函數(shù)中也作了相應(yīng)的修改),避免了對狀態(tài)數(shù)組的轉(zhuǎn)置操作, 加快了加密與解密的速度。 6、提供了檢查所選擇的存放加密/解密文件的磁盤空間是否足夠的功能。對于所選擇的磁盤空間不夠時不會給出提示,并不進行加密/解密,以免浪費時間。 7、添加了可以根據(jù)所選密鑰長度類型,從指定文件中導入密鑰的功能(注:在從給定的文件中所讀入的字符串中若是有
