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 <string.h> 17 #include <memory.h> 18 #include "md2.h" 19 20 /*********************** FUNCTION DEFINITIONS ***********************/ 21 int md2_test() 22 { 23 BYTE text1[] = {"abc"}; 24 BYTE text2[] = {"abcdefghijklmnopqrstuvwxyz"}; 25 BYTE text3_1[] = {"ABCDEFGHIJKLMNOPQRSTUVWXYZabcde"}; 26 BYTE text3_2[] = {"fghijklmnopqrstuvwxyz0123456789"}; 27 BYTE hash1[MD2_BLOCK_SIZE] = {0xda,0x85,0x3b,0x0d,0x3f,0x88,0xd9,0x9b,0x30,0x28,0x3a,0x69,0xe6,0xde,0xd6,0xbb}; 28 BYTE hash2[MD2_BLOCK_SIZE] = {0x4e,0x8d,0xdf,0xf3,0x65,0x02,0x92,0xab,0x5a,0x41,0x08,0xc3,0xaa,0x47,0x94,0x0b}; 29 BYTE hash3[MD2_BLOCK_SIZE] = {0xda,0x33,0xde,0xf2,0xa4,0x2d,0xf1,0x39,0x75,0x35,0x28,0x46,0xc3,0x03,0x38,0xcd}; 30 BYTE buf[16]; 31 MD2_CTX ctx; 32 int pass = 1; 33 34 md2_init(&ctx); 35 md2_update(&ctx, text1, strlen(text1)); 36 md2_final(&ctx, buf); 37 pass = pass && !memcmp(hash1, buf, MD2_BLOCK_SIZE); 38 39 // Note that the MD2 object can be re-used. 40 md2_init(&ctx); 41 md2_update(&ctx, text2, strlen(text2)); 42 md2_final(&ctx, buf); 43 pass = pass && !memcmp(hash2, buf, MD2_BLOCK_SIZE); 44 45 // Note that the data is added in two chunks. 46 md2_init(&ctx); 47 md2_update(&ctx, text3_1, strlen(text3_1)); 48 md2_update(&ctx, text3_2, strlen(text3_2)); 49 md2_final(&ctx, buf); 50 pass = pass && !memcmp(hash3, buf, MD2_BLOCK_SIZE); 51 52 return(pass); 53 } 54 55 int main() 56 { 57 printf("MD2 tests: %s\n", md2_test() ?
