| 40 | =head1 NOTES
|
|---|
| 41 |
|
|---|
| 42 | Developers should be aware of the negative performance implications of
|
|---|
| 43 | calling these functions multiple times and should consider using
|
|---|
| 44 | L<EVP_CIPHER_fetch(3)> instead.
|
|---|
| 45 | See L<crypto(7)/Performance> for further information.
|
|---|
| 46 |
|
|---|
| 47 | =head1 RETURN VALUES
|
|---|
| 48 |
|
|---|
| 49 | These functions return an B<EVP_CIPHER> structure that contains the
|
|---|
| 50 | implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
|
|---|
| 51 | details of the B<EVP_CIPHER> structure.
