| 16 | |
| Matt Caswell | f3cd81d | 2016-04-06 11:19:55 +0100 | [diff] [blame] | 17 | Prior to OpenSSL 1.1.0 RAND_cleanup() erases the memory used by the PRNG. This |
| 18 | function is deprecated and as of version 1.1.0 does nothing. No explicit |
| 19 | initialisation or de-initialisation is necessary. See L<OPENSSL_init_crypto(3)>. |
