MD5collision实验通关代码

注意建议先执行task4

task1
echo “a”>prefix
md5collgen -p prefix -o out1.bin out2.bin
md5sum out1.bin out2.bin
sha256sum out1.bin out2.bin
xxd out1.bin
xxd out2.bin
finish
exit

task2
echo “ac”>prefix
md5collgen prefix -o out1.bin out2.bin
echo “ass”>suffix
cat out1.bin suffix.txt > out1_long.bin
cat out2.bin suffix.txt > out2_long.bin
md5sum out1_long.bin out2_long.bin
sha256sum out1_long.bin out2_long.bin
finish
exit

task3
hex task3
vi task3.sh
(3040;prefix P suffix;prefix Q suffix)
./task3.sh
md5sum a1.out a2.out
sha256sum a2.out a1.out
./a1.out
./a2.out
finish
exit

task4
hex task4
vi task4-1.sh
(3040)
vi task4-2.sh
(120;prefix P suffix_1 P suffix_2;prefix Q suffix_1 P suffix_2)
./task4-1.sh
./task4-2.sh
md5sum a1.out a2.out
sha256sum a1.out a2.out
./a1.out
./a2.out
finish
exit

task5
echo “print(“Hello”)”>task5.py
md5collgen -o out1.py out2.py
md5sum out1.py out2.py
hex out1.py
hex out2.py
finish
exit
