| =head1 NAME
 | |
| 
 | |
| RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final -
 | |
| RIPEMD-160 hash function
 | |
| 
 | |
| =head1 SYNOPSIS
 | |
| 
 | |
|  #include <openssl/ripemd.h>
 | |
| 
 | |
| The following functions have been deprecated since OpenSSL 3.0, and can be
 | |
| hidden entirely by defining B<OPENSSL_API_COMPAT> with a suitable version value,
 | |
| see L<openssl_user_macros(7)>:
 | |
| 
 | |
|  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);
 | |
| 
 | |
| =head1 DESCRIPTION
 | |
| 
 | |
| All of the functions described on this page are deprecated.
 | |
| Applications should instead use L<EVP_DigestInit_ex(3)>, L<EVP_DigestUpdate(3)>
 | |
| and L<EVP_DigestFinal_ex(3)>.
 | |
| 
 | |
| RIPEMD-160 is a cryptographic hash function with a
 | |
| 160 bit output.
 | |
| 
 | |
| RIPEMD160() computes the RIPEMD-160 message digest of the B<n>
 | |
| bytes at B<d> and places it in B<md> (which must have space for
 | |
| RIPEMD160_DIGEST_LENGTH == 20 bytes of output). If B<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 B<RIPEMD160_CTX> structure.
 | |
| 
 | |
| RIPEMD160_Update() can be called repeatedly with chunks of the message to
 | |
| be hashed (B<len> bytes at B<data>).
 | |
| 
 | |
| RIPEMD160_Final() places the message digest in B<md>, which must have
 | |
| space for RIPEMD160_DIGEST_LENGTH == 20 bytes of output, and erases
 | |
| the B<RIPEMD160_CTX>.
 | |
| 
 | |
| =head1 RETURN VALUES
 | |
| 
 | |
| RIPEMD160() returns a pointer to the hash value.
 | |
| 
 | |
| RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for
 | |
| success, 0 otherwise.
 | |
| 
 | |
| =head1 NOTE
 | |
| 
 | |
| Applications should use the higher level functions
 | |
| L<EVP_DigestInit(3)> etc. instead of calling these
 | |
| functions directly.
