[Richard Levitte]
Changes between 1.1.1 and 1.1.1a [xx XXX xxxx]
*) Fixed the issue that RAND_add()/RAND_seed() silently discards random input
if its length exceeds 4096 bytes. The limit has been raised to a buffer size
of two gigabytes and the error handling improved.
This issue was reported to OpenSSL by Dr. Falko Strenzke. It has been
categorized as a normal bug, not a security issue, because the DRBG reseeds
automatically and is fully functional even without additional randomness
provided by the application.
Changes between 1.1.0i and 1.1.1 [11 Sep 2018]

There are two phases to the use of DES encryption. The first is the

actual encryption. A DES key is of type I<DES_cblock>. This type
