Fundamentally, since its inception by EAY years ago, "OpenSSL"
has provided two things to other software developers: A very
popular implementation of the SSL protocols defined by
Netscape/Mozilla/IETF, and an equally popular library of
fundamental cryptographic building blocks such as large
numbers and various types of encryption and decryption.
My criticism of the OpenSSL changes in the future version
1.1.0 is that they are removing the most flexible building
blocks from the part that is intended to be used.

2014 saw some widely published problems with various SSL
"Heartbleed" was a programming error found *only* in
the OpenSSL SSL code and did not affect the handful of
competing SSL implementations (such as the NSS one by
Mozilla and the STUNNEL one by Microsoft). Essentially,
heartbleed allowed people to put a hook through the
keyhole and steal the key from behind the locked door.
"Poodle" was a new way to attack a known weakness in
the old version 3.0 of the SSL protocol, affecting all
implementations, combined with a weakness in how Web
Browsers work around bad SSL libraries that refuse to
even reply to requests for protocol version 3.1 ("TLS
1.0"). On top of that, it turned out that a few minor
competing SSL implementations (not OpenSSL, NSS and
STUNNEL) never implemented the TLS 1.0 protection
against the known weakness, leading to a rumor that
poodle affected all "TLS 1.0" implementations, and
not just the few broken ones.
