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 "sha1.h" 19 20 /*********************** FUNCTION DEFINITIONS ***********************/ 21 int sha1_test() 22 { 23 BYTE text1[] = {"abc"}; 24 BYTE text2[] = {"abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq"}; 25 BYTE text3[] = {"aaaaaaaaaa"}; 26 BYTE hash1[SHA1_BLOCK_SIZE] = {0xa9,0x99,0x3e,0x36,0x47,0x06,0x81,0x6a,0xba,0x3e,0x25,0x71,0x78,0x50,0xc2,0x6c,0x9c,0xd0,0xd8,0x9d}; 27 BYTE hash2[SHA1_BLOCK_SIZE] = {0x84,0x98,0x3e,0x44,0x1c,0x3b,0xd2,0x6e,0xba,0xae,0x4a,0xa1,0xf9,0x51,0x29,0xe5,0xe5,0x46,0x70,0xf1}; 28 BYTE hash3[SHA1_BLOCK_SIZE] = {0x34,0xaa,0x97,0x3c,0xd4,0xc4,0xda,0xa4,0xf6,0x1e,0xeb,0x2b,0xdb,0xad,0x27,0x31,0x65,0x34,0x01,0x6f}; 29 BYTE buf[SHA1_BLOCK_SIZE]; 30 int idx; 31 SHA1_CTX ctx; 32 int pass = 1; 33 34 sha1_init(&ctx); 35 sha1_update(&ctx, text1, strlen(text1)); 36 sha1_final(&ctx, buf); 37 pass = pass && !memcmp(hash1, buf, SHA1_BLOCK_SIZE); 38 39 sha1_init(&ctx); 40 sha1_update(&ctx, text2, strlen(text2)); 41 sha1_final(&ctx, buf); 42 pass = pass && !memcmp(hash2, buf, SHA1_BLOCK_SIZE); 43 44 sha1_init(&ctx); 45 for (idx = 0; idx < 100000; ++idx) 46 sha1_update(&ctx, text3, strlen(text3)); 47 sha1_final(&ctx, buf); 48 pass = pass && !memcmp(hash3, buf, SHA1_BLOCK_SIZE); 49 50 return(pass); 51 } 52 53 int main() 54 { 55 printf("SHA1 tests: %s\n", sha1_test() ?
