MD4 and MD5 hash functions
#include <openssl/md4.h>unsigned char *
MD4(const unsigned char *d, unsigned long n, unsigned char *md); int
MD4_Init(MD4_CTX *c); int
MD4_Update(MD4_CTX *c, const void *data, unsigned long len); int
MD4_Final(unsigned char *md, MD4_CTX *c);
#include <openssl/md5.h>unsigned char *
MD5(const unsigned char *d, unsigned long n, unsigned char *md); int
MD5_Init(MD5_CTX *c); int
MD5_Update(MD5_CTX *c, const void *data, unsigned long len); int
MD5_Final(unsigned char *md, MD5_CTX *c);
MD5() compute the MD4 and MD5 message digest of the n bytes at d and place it in md, which must have space for
MD5_DIGEST_LENGTH== 16 bytes of output. If md is
NULL, the digest is placed in a static array. The following functions may be used if the message is not completely stored in memory:
MD5_Init() initializes a MD5_CTX structure.
MD5_Update() can be called repeatedly with chunks of the message to be hashed (len bytes at data).
MD5_Final() places the message digest in md, which must have space for
MD5_DIGEST_LENGTH== 16 bytes of output, and erases the MD5_CTX.
MD4_Final() are analogous using an MD4_CTX structure. Applications should use the higher level functions EVP_DigestInit(3) etc. instead of calling these hash functions directly.
MD5() return pointers to the hash value.
MD5_Final() return 1 for success or 0 otherwise. EVP_DigestInit(3)
MD5_Final() appeared in SSLeay 0.4 or earlier and have been available since OpenBSD 2.4.
MD4_Final() first appeared in OpenSSL 0.9.6 and have been available since OpenBSD 2.9.
