RIPEMD160(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 );

  void RIPEMD160_Init(
	  RIPEMD160_CTX *c );

  void RIPEMD160_Update(
	  RIPEMD_CTX *c, const void *data,		      unsigned long
  len );

  void RIPEMD160_Final(
	  unsigned char *md, RIPEMD160_CTX *c );

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

  The RIPEMD160() function 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:

  The RIPEMD160_Init() function initializes a RIPEMD160_CTX structure.

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

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

  Applications should use the higher level functions , such as
  EVP_DigestInit(), instead of calling the hash functions directly.

  The ripemd() function conforms to ISO/IEC 10118-3 (draft).

RETURN VALUES
  The RIPEMD160() function returns a pointer to the hash value.

  The RIPEMD160_Init(), RIPEMD160_Update(), and RIPEMD160_Final() functions
  do not return values.

HISTORY
  The RIPEMD160(), RIPEMD160_Init(), RIPEMD160_Update(), and
  RIPEMD160_Final() functions are available since SSLeay 0.9.0.
