=head1 DESCRIPTION
|
|
|
|
MD4 is a cryptographic hash function standardized in RFC 1320 and designed by
|

=head1 NOTES
|
|
|
|
Developers should be aware of the negative performance implications of
|
|
calling this function multiple times and should consider using
|
|
L<EVP_MD_fetch(3)> with L<EVP_MD-MD4(7)> instead.
|
|
See L<crypto(7)/Performance> for further information.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
These functions return a B<EVP_MD> structure that contains the
|
|
implementation of the message digest. See L<EVP_MD_meth_new(3)> for
|
|
details of the B<EVP_MD> structure.
|
|
|
|

|
|
