NAME

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

SYNOPSIS

10        #include <openssl/ripemd.h>
11
12       The following functions have been deprecated since OpenSSL 3.0, and can
13       be hidden entirely by defining OPENSSL_API_COMPAT with a suitable
14       version value, see openssl_user_macros(7):
15
16        unsigned char *RIPEMD160(const unsigned char *d, unsigned long n,
17                                 unsigned char *md);
18
19        int RIPEMD160_Init(RIPEMD160_CTX *c);
20        int RIPEMD160_Update(RIPEMD160_CTX *c, const void *data, unsigned long len);
21        int RIPEMD160_Final(unsigned char *md, RIPEMD160_CTX *c);
22

DESCRIPTION

24       All of the functions described on this page are deprecated.
25       Applications should instead use EVP_DigestInit_ex(3),
26       EVP_DigestUpdate(3) and EVP_DigestFinal_ex(3).
27
28       RIPEMD-160 is a cryptographic hash function with a 160 bit output.
29
30       RIPEMD160() computes the RIPEMD-160 message digest of the n bytes at d
31       and places it in md (which must have space for RIPEMD160_DIGEST_LENGTH
32       == 20 bytes of output). If md is NULL, the digest is placed in a static
33       array.
34
35       The following functions may be used if the message is not completely
36       stored in memory:
37
38       RIPEMD160_Init() initializes a RIPEMD160_CTX structure.
39
40       RIPEMD160_Update() can be called repeatedly with chunks of the message
41       to be hashed (len bytes at data).
42
43       RIPEMD160_Final() places the message digest in md, which must have
44       space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases the
45       RIPEMD160_CTX.
46

RETURN VALUES

48       RIPEMD160() returns a pointer to the hash value.
49
50       RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for
51       success, 0 otherwise.
52

NOTE

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