NAME

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

SYNOPSIS

        #include <openssl/ripemd.h>

        unsigned char *RIPEMD160(const unsigned char *d, unsigned long n,
                                 unsigned char *md);

        int RIPEMD160_Init(RIPEMD160_CTX *c);
        int RIPEMD160_Update(RIPEMD_CTX *c, const void *data, unsigned long len);
        int RIPEMD160_Final(unsigned char *md, RIPEMD160_CTX *c);

DESCRIPTION

       RIPEMD-160 is a cryptographic hash function with a 160 bit output.

       RIPEMD160() computes the RIPEMD-160 message digest of the n bytes at d and places it in md
       (which must have space for RIPEMD160_DIGEST_LENGTH == 20 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:

       RIPEMD160_Init() initializes a RIPEMD160_CTX structure.

       RIPEMD160_Update() can be called repeatedly with chunks of the message to be hashed (len
       bytes at data).

       RIPEMD160_Final() places the message digest in md, which must have space for
       RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases the RIPEMD160_CTX.

RETURN VALUES

       RIPEMD160() returns a pointer to the hash value.

       RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for success, 0
       otherwise.

NOTE

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