In contrast, closed-source software is easier to place back doors or traps, and the NSA key found in the Windows operating system is compelling evidence. Open source can bring security Closed-source software is no better than the security of Open-source software, and, conversely, OSS has the capacity and potential to provide better security, as evidenced by the following examples: OpenBSD, currently o

, and slower, but safer, and better at resistance to analysis and differentiation. 3) SHA1 and others The SHA1 is designed by the NIST NSA to work with DSA, which produces a 160bit hash value for inputs that are less than 264 in length, and therefore has a better anti-poor (brute-force) nature. The SHA-1 design is based on the same principle as the MD4 and imitates the algorithm. So what's the use of these hash algorithms? The application of hash
