用vb实现的文本加密算法

VHDL implementation of the twofish cipher for 128,192 and 256 bit keys. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.-VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.

对音频信号分帧加窗,对每帧进行三阶小波变换,取其逼近系数平均值(一般为零).在此嵌入二值图像 并有对潜入水印信号进行盲检,恢复其嵌入水印-Sub-frame of the audio signal increases the Hamming window for each frame impletment third-order wavelet transform, whichever is close to the average coefficient (usually zero). according to this embedding binary image and resume its embedded watermark from the watermark signal by the Blind detection

硬件求解平方根源代码加密 (硬件求解平方根的，将license添加到原有的MaxplusII或QuartusII的license中就可以直接使用，但源代码加密。altera提供 )-solving square root of the hardware encryption code (square root of the hardware solution will be added to the original license MaxplusII or Quartus II of the license which can be directly used, but the source code encryption. ALTERA provide)

线性移位寄存器是流密码的重要组成部分，该程序就是实现该方法。- The linearity shift register is the stream cipher important constituent, this procedure realizes this method.
