=head1 NOTES
|
|
|
|
Developers should be aware of the negative performance implications of
|
|
calling these functions multiple times and should consider using
|
|
L<EVP_CIPHER_fetch(3)> with L<EVP_CIPHER-BLOWFISH(7)> instead.
|
|
See L<crypto(7)/Performance> for further information.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
These functions return an B<EVP_CIPHER> structure that contains the
|
|
implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
|
|
details of the B<EVP_CIPHER> structure.
