|
|
RIPEMD160, RIPEMD160_Init, RIPEMD160_Update, RIPEMD160_Final -
|
RIPEMD-160 hash function
|
|
=head1 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);
|
|
=head1 DESCRIPTION
|
|
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>.
|
|
Applications should use the higher level functions
|
L<EVP_DigestInit(3)|EVP_DigestInit(3)> etc. instead of calling the
|
hash functions directly.
|
|
=head1 RETURN VALUES
|
|
RIPEMD160() returns a pointer to the hash value.
|
|
RIPEMD160_Init(), RIPEMD160_Update() and RIPEMD160_Final() return 1 for
|
success, 0 otherwise.
