Caesar-code
凯撒密码作为一种最为古老的对称加密体制,在古罗马的时候都已经很流行,他的基本思想是:通过把字母移动一定的位数来实现加密和解密。例如,如果密匙是把明文字母的位数向后移动三位,那么明文字母B就变成了密文的E,依次类推,X将变成A,Y变成B,Z变成C,由此可见,位数就是凯撒密码加密和解密的密钥。个人原创。(Caesar password as one of the most ancient symmetric encryption system in ancient Rome have been very popular, his basic idea is: by the letters move a certain number of bits to achieve encryption and decryption. For example, if the key is the number of bits of plaintext letters backward move three, the plaintext letter B into a ciphertext E, and so on, X will become Y-become a B,, and Z becomes C Thus, the median is the Caesar cipher encryption and decryption keys. Personal originality.)

ECC_TEST
椭圆曲线(ECC)算法是一种公钥算法,它比流行的RSA算法有很多优点:
1)安全性能更高 , 如160位ECC与1024位RSA、DSA有相同的安全强度。
2)计算量小,处理速度快, 在私钥的处理速度上(解密和签名),ECC比RSA、DSA快得多。
3)存储空间占用小 ECC的密钥尺寸和系统参数与RSA、DSA相比要小得多, 所以占用的存储空间小得多。
4)带宽要求低。(OPENSSL ECC
