14=head1 DESCRIPTION
15
16RIPEMD-160 is a cryptographic hash function first published in 1996 belonging
17to the RIPEMD family (RACE Integrity Primitives Evaluation Message Digest).
18This implementation is only available with the legacy provider.

20=over 4
21
22=item EVP_ripemd160()
23
24The RIPEMD-160 algorithm which produces a 160-bit output from a given input.

28=head1 NOTES
29
30Developers should be aware of the negative performance implications of
31calling this function multiple times and should consider using
32L<EVP_MD_fetch(3)> with L<EVP_MD-RIPEMD160(7)> instead.
33See L<crypto(7)/Performance> for further information.
34
35=head1 RETURN VALUES
36
37These functions return a B<EVP_MD> structure that contains the
38implementation of the message digest. See L<EVP_MD_meth_new(3)> for
39details of the B<EVP_MD> structure.
