These tests do not encompass the full 8 range of available test vectors, however, if the tests 9 pass it is very, very likely that the code is correct 10 and was compiled properly. This code also serves as 11 example usage of the functions. 12 *********************************************************************/ 13 14 /*************************** HEADER FILES ***************************/ 15 #include <stdio.h> 16 #include <memory.h> 17 #include <string.h> 18 #include "md5.h" 19 20 /*********************** FUNCTION DEFINITIONS ***********************/ 21 int md5_test() 22 { 23 BYTE text1[] = {""}; 24 BYTE text2[] = {"abc"}; 25 BYTE text3_1[] = {"ABCDEFGHIJKLMNOPQRSTUVWXYZabcde"}; 26 BYTE text3_2[] = {"fghijklmnopqrstuvwxyz0123456789"}; 27 BYTE hash1[MD5_BLOCK_SIZE] = {0xd4,0x1d,0x8c,0xd9,0x8f,0x00,0xb2,0x04,0xe9,0x80,0x09,0x98,0xec,0xf8,0x42,0x7e}; 28 BYTE hash2[MD5_BLOCK_SIZE] = {0x90,0x01,0x50,0x98,0x3c,0xd2,0x4f,0xb0,0xd6,0x96,0x3f,0x7d,0x28,0xe1,0x7f,0x72}; 29 BYTE hash3[MD5_BLOCK_SIZE] = {0xd1,0x74,0xab,0x98,0xd2,0x77,0xd9,0xf5,0xa5,0x61,0x1c,0x2c,0x9f,0x41,0x9d,0x9f}; 30 BYTE buf[16]; 31 MD5_CTX ctx; 32 int pass = 1; 33 34 md5_init(&ctx); 35 md5_update(&ctx, text1, strlen(text1)); 36 md5_final(&ctx, buf); 37 pass = pass && !memcmp(hash1, buf, MD5_BLOCK_SIZE); 38 39 // Note the MD5 object can be reused. 40 md5_init(&ctx); 41 md5_update(&ctx, text2, strlen(text2)); 42 md5_final(&ctx, buf); 43 pass = pass && !memcmp(hash2, buf, MD5_BLOCK_SIZE); 44 45 // Note the data is being added in two chunks. 46 md5_init(&ctx); 47 md5_update(&ctx, text3_1, strlen(text3_1)); 48 md5_update(&ctx, text3_2, strlen(text3_2)); 49 md5_final(&ctx, buf); 50 pass = pass && !memcmp(hash3, buf, MD5_BLOCK_SIZE); 51 52 return(pass); 53 } 54 55 int main() 56 { 57 printf("MD5 tests: %s\n", md5_test() ?
