Animated_C2123858182008
- Usually we see static Captcha, now we will make an imated Captcha. Now this cool. What does the captcha look like? It just like the ordinary Captcha, the difference is the letters are moving and animated. You can set your Captcha setting quickly suc
Basic_Capt212557922008
- How to make a very basic captcha image and validate the form input to make sure the code matches. Does not use sessions of any sort. The image also just uses the built in PHP fonts so no need to load font files. I also put three random lines in the

rc4
- 实现RC4加密算法，其是密钥长度可变的流加密算法簇。之所以称其为簇，是由于其核心部分的S-box长度可为任意，但一般为256字节。该算法的速度可以达到DES加密的10倍左右。RC4算法的原理很简单，包括初始化算法和伪随机子密码生成算法两大部分。-RC4 encryption algorithm to achieve, it is the variable key length stream cipher algorithm clusters. It is called a cluster, i

KG
- 序列密码也称为流密码（Stream Cipher），它是对称密码算法的一种。序列密码具有实现简单、便于硬件实施、加解密处理速度快、没有或只有有限的错误传播等特点，因此在实际应用中，特别是专用或机密机构中保持着优势，典型的应用领域包括无线通信、外交通信。若能以一种方式产生一随机序列（密钥流），这一序列由密钥所确定，则利用这样的序列就可以进行加密，即将密钥、明文表示成连续的符号或二进制，对应地进行加密。-Stream cipher is also known as Stream Cipher (St
