BUAA-CryptoLab

BUAA-Cryptolab,consists of some basic crypto algorithms and some baby exploit scripts.

description

• lab1

  Lab1 includes some basic arithmetic functions which we learned in AITMC.For instance,exCRT,miller-Rabin prime test,print all primes within $5\times 10^{10}$​ by sieve of Euler and bitset.Some of them were written in CryptoLab.py.

• lab2

  $GF(2^8)$​ Galois field's operations.

• lab3

  classical cryptography

• lab4

  DES & some optimization of DES from speed and safety.

• lab5

  AES & the generation of SBOX.

• lab6

  Block cipher's working pattern by SM4,contained ECB,CBC,CTR,CFB,and also padding oracle attack to CBC mode.

• lab7

  Lab7 is about stream cipher: BBS,RC4 and ZUC.

• lab8

  Lab8 is the big project1:Try to accelerate your encryption function.I choose to accelerate SM4,eventually,its speed is 1.06Gb/s.

• lab9

  Lab9 is about rsa and rsa's very classic attacking methods,like the wiener attack.

• lab10

  Lab10 is about elliptic curve,its arithmetic and encoding of messages in transit,Diffie Hellman demo and SM2 digital signature demo.

• lab11

  Lab11 is about hash,such as SHA1.py,SM3.py.It's very pity that I have no time to play with the second birthday attack. That sounds very intriguing.

• lab12

  Lab12 is the big project2.I choose the hacking part and helped the assistant to build 5 services on our school's CTFd. Here are those 5 services' code and dockerfile.

• lab13

  Lab13 is about digital signature.It contains 3 signature demos with 3 different algorithms.

the flowchartgen.py is used to generate a flowchart of the program.
