Dear all: I try to understand RSA-OAEP with rsa_test.c and I have some questions about this file. 1. If the number is 1234567893456 in dec, that is 11F71FB11D0 in hec, how should I put it in the static unsigned char n[]? Should I put is as "\x1\x1F\x71\xFB\x11\xD0", I marked this one as order A, or "\xD0\x11\xFB\x71\x1F\x1", I marked it as order B?
2. In RSA_test.c, the key1 has the n as "\x00\xAA\x36\xAB\xCE\x88\xAC\xFD\xFF\x55\x52\x3C\x7F\xC4\x52\x3F" "\x90\xEF\xA0\x0D\xF3\x77\x4A\x25\x9F\x2E\x62\xB4\xC5\xD9\x9C\xB5" "\xAD\xB3\x00\xA0\x28\x5E\x53\x01\x93\x0E\x0C\x70\xFB\x68\x76\x93" "\x9C\xE6\x16\xCE\x62\x4A\x11\xE0\x08\x6D\x34\x1E\xBC\xAC\xA0\xA1" "\xF5" What does the first "\x00" mean? If the order of n is order A, defined in the question 1, it seems useless. If the order of n is order B, BN_num_bytes tells me the # of bytes is 64, but it should be 65. 3. How could I print the RSA_fail and RSA_erro strings? I trace the procedure to the ERR_load_RSA_strings but I have no ideas how to print it out of the standard output. 4. How could I print bn number out of the standard output?
