加密算法
Test Driver for Crypto++, a C++ Class Library of Cryptographic Primitives:
- To generate an RSA key
cryptest g
- To encrypt and decrypt a string using RSA
cryptest r
- To calculate MD5, SHS, and RIPEMD-160 message digests:
cryptest m file
- To encrypt and decrypt a string using DES-EDE in CBC mode:
cryptest t
- To encrypt or decrypt a file
cryptest e|d input output
- To share a file into shadows:
cryptest s <pieces> <pieces-needed> file
(make sure file has no extension, if you re running this under DOS)
- To reconstruct a file from shadows:
cryptest j output file1 file2 [....]
- To gzip a file:
cryptest z <compression-level> input output
- To gunzip a file:
cryptest u input output
- To run validation tests:
cryptest v
- To run benchmarks:
cryptest b [time for each benchmark in seconds]
工程計(jì)算MATLAB code to calculate the reorthogonalized sine tapers
input: N = the length of the time series data to be tapered
p = the number of tapers requested
I = the gap structure a vector of length N
I(t) = 1 if there is data at time t, t=1, ..., N
I(t) = 0 if there is a gap at time t
output: X = N-by-p vector of the reorthogonalized sine taper
his project was built and tested with WinAVR-20060125.
Make sure the MCU target define in the Makefiles corresponds to the AVR you are using!!
To build the code, just install WinAVR and run "make" from the console in echomaster and
echoslave subdirs.
"make program" will program the device if you have a AVRISP attached.
Remember to set the AVR device to at least 8MHz. The AVR may use the programmable clock
from MC1319x, just remember to check if the MC1319x and SPI communication is working FIRST!
Otherwise you wont get any clock signal to the AVR and then you can t program it or reset
the fuses!
The MC1319x has default clock output of 32kHz so you will have to set your programmer to
a very low frequency (<=32kHz/4) to be able to program it while it is running on that!
8點(diǎn)基二fft
Fast Fourier Transform (FFT).
Using 8 points, takes about 1.2 ms to execute one FFT.
Sets up General Purpose Timer 1 to generate events at 10 kHz.
Will produce 10 kHz output on T1PWM and T1PWM pins.
The book "The Finite Difference Time Domain for Electromagnetics" by Karl Kunz and Raymond Luebbers, CRC Press, 1993, contains an FDTD code and output files in Appendix B. The same code and output files are contained in this directory.
EXAMPLE SOURCE CODE FOR IMPLIB FILTER
This filter accepts input through the standard input stream, convertsit and outputs it to the standard output am. The streams are linkedthrough pipes, such that the input stream is the output from the import librarian being invoked, and the output stream is connected to the message window of the IDE, ie.
EXAMPLE SOURCE CODE FOR TASM FILTER
his filter accepts input through the standard input stream, converts it and outputs it to the standard output stream. The streams are linked
through pipes, such that the input stream is the output from the assembler
being invoked, and the output stream is connected to the message window of the IDE, ie.

* AT N+1 EQUALLY SPACED POINTS IN THE INTERVAL [A,B].
