文件加密使用,可以实现对PC上文件进行加密解密功能(document encryption use, the PC can be achieved on the document encryption and decryption functions)

sha256的签名算法，纯C实现，已验证正确，在控制台上直接运行即可，(sha256 signature algorithm, pure C implementation ，has been verified properly and can be run directly on the console.)

本程序是仿射密码的加密与解密，用C语言编写的，经测试没有问题(This procedure is affine password encryption and decryption, written in C, tested no problem)

整体思路 用createkey.java 文件来产生秘钥，用jiami.java 文件来实 现加密，用jiemi.java 文件来实现解密,用BigInteger.java 来实现 大数的表示及运算，用rsa.java 来实现前端图形界面显示。有关函 数见五个文件里的具体实现。 (The overall outlook createkey.java document used to generate secret keys, used to achieve jiami.java file encryption, used to achieve jiemi.java documents declassified by BigInteger.java to achieve expression of large numbers and calculations, using rsa.java to achieve front-end graphical interface display. Related functions, see the five concrete realization of the document.)

用C/C++实现加解密算法及其应用：AES 和基于AES 的CMAC(Encryption and decryption algorithm and its application with C/C++: AES and CMAC based on AES)

Program that runs AES/RSA algorithm multiple times for different input values and outputs their run times for benchmarking purposes. Written in Visual C#

此为Keeloq算法的解密C代码，keeloq最常用于无线门锁装置。(KeeLoq is a proprietary hardware-dedicated NLFSR-based block cipher. The uni-directional command transfer protocol was designed by Frederick Bruwer, PhD, CEO at Nanoteq (Pty) Ltd)

一个周期3的多表代替密码，第1个表由密钥字法产生（密钥字自拟），第2个表由洗牌法产生（注意，字母a~z与数字0~25一一对应），第三个表由公式法产生（数学公式自拟，注意它须是Z26上的一个一一变换）(a cycle of three multi-table instead of passwords, a table by key word method, (key word from the intended), Table No. 2 produced by shuffling method (note, a letter with a number of z ~ 0 ~ 25 he gathers), 3rd tables generated by the formula (from the proposed mathematical formula, it should pay attention to the Z26 is a transformation on January 1))

对于ECC 进行加密解密运算，这里主要是ECDSA的签名(For ECC encryption and decryption operations, where mainly ECDSA signature)
