Files like dh.pod, etc., mostly duplicated the API-specific pod files. Removed the duplicated content; that often mean the whole file could be removed. Some of the content about internals got moved into README files in the source tree. Some content (e.g., err.pod) got moved into other pod pages.

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>.
|
|
|
|
=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.
