NAME

6       RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final -
7       RIPEMD-160 hash function

SYNOPSIS

10        #include <openssl/ripemd.h>
11
12        unsigned char *RIPEMD160(const unsigned char *d, unsigned long n,
13                                 unsigned char *md);
14
15        int RIPEMD160_Init(RIPEMD160_CTX *c);
16        int RIPEMD160_Update(RIPEMD160_CTX *c, const void *data, unsigned long len);
17        int RIPEMD160_Final(unsigned char *md, RIPEMD160_CTX *c);

DESCRIPTION

20       RIPEMD-160 is a cryptographic hash function with a 160 bit output.
21
22       RIPEMD160() computes the RIPEMD-160 message digest of the n bytes at d
23       and places it in md (which must have space for RIPEMD160_DIGEST_LENGTH
24       == 20 bytes of output). If md is NULL, the digest is placed in a static
25       array.
26
27       The following functions may be used if the message is not completely
28       stored in memory:
29
30       RIPEMD160_Init() initializes a RIPEMD160_CTX structure.
31
32       RIPEMD160_Update() can be called repeatedly with chunks of the message
33       to be hashed (len bytes at data).
34
35       RIPEMD160_Final() places the message digest in md, which must have
36       space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases the
37       RIPEMD160_CTX.
38

RETURN VALUES

40       RIPEMD160() returns a pointer to the hash value.
41
42       RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for
43       success, 0 otherwise.

NOTE

46       Applications should use the higher level functions EVP_DigestInit(3)
47       etc. instead of calling these functions directly.
