RIPEMD160_INIT(3)                   OpenSSL                  RIPEMD160_INIT(3)
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(RIPEMD160_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.
