Hi, In the file: profiling\aes_example\spy.cpp Why the key[] are all 0x00? In the code line: “int fd = open("./libcrypto.so", O_RDONLY);”， is the libcrypto.so a special file which must be reloaded? Or can I replace it with other any .so file? The size of this file must can full reload in the L1 Cache or L2 Cache size? What is the function of maccess(void *p)?

feel free to change the key.

this is the code to attack the OpenSSL AES T-Table implementation, you need to compile that first.

Read the source code ;)
