This code was 26 * written by Colin Plumb in 1993, no copyright is claimed. 27 * This code is in the public domain; do with it what you wish. 28 * 29 * Equivalent code is available from RSA Data Security, Inc. 30 * This code has been tested against that, and is equivalent, 31 * except that you don't need to include two pages of legalese 32 * with every copy. 33 * 34 * To compute the message digest of a chunk of bytes, declare an 35 * MD5Context structure, pass it to MD5Init, call MD5Update as 36 * needed on buffers full of bytes, and then call MD5Final, which 37 * will fill a supplied 16-byte array with the digest. 38 * 39 * Changed so as no longer to depend on Colin Plumb's `usual.h' 40 * header definitions; now uses stuff from dpkg's config.h 41 * - Ian Jackson <ijackson@nyx.cs.du.edu>. 42 * Still in the public domain. 43 */ 44 45 #ifndef ISC_MD5_H 46 #define ISC_MD5_H 1 47 48 #include <isc/lang.h> 49 #include <isc/platform.h> 50 #include <isc/types.h> 51 52 #define ISC_MD5_DIGESTLENGTH 16U 53 #define ISC_MD5_BLOCK_LENGTH 64U 54 55 #ifdef ISC_PLATFORM_OPENSSLHASH 56 #include <openssl/evp.h> 57 58 typedef EVP_MD_CTX isc_md5_t; 59 60 #elif PKCS11CRYPTO 61 #include <pk11/pk11.h> 62 63 typedef pk11_context_t isc_md5_t; 64 65 #else 66 67 typedef struct { 68 isc_uint32_t buf[4]; 69 isc_uint32_t bytes[2]; 70 isc_uint32_t in[16]; 71 } isc_md5_t; 72 #endif 73 74 ISC_LANG_BEGINDECLS 75 76 void 77 isc_md5_init(isc_md5_t *ctx); 78 79 void 80 isc_md5_invalidate(isc_md5_t *ctx); 81 82 void 83 isc_md5_update(isc_md5_t *ctx, const unsigned char *buf, unsigned int len); 84 85 void 86 isc_md5_final(isc_md5_t *ctx, unsigned char *digest); 87 88 ISC_LANG_ENDDECLS 89 90 #endif /* ISC_MD5_H */ 91
