Subject: [PATCH 1/2] Fixes ERL-675
RSA options rsa_mgf1_md, rsa_oaep_md, and rsa_oaep_label do not work.
PR #838, which reimplemented various parts of the crypto application to use
OpenSSL EVP APIs was merged manually. During the manual merge the macro
define for HAVE_RSA_OAEP_MD was lost. The result being that setting
rsa_mgf1_md and rsa_oaep_md for any other value than sha causes the nif to
Support for configurable MGF1 digests and OAEP labels is available in
OpenSSL version 1.1.0, a cursory look at libressl does not seem to reveal
support, so it is not added in this PR.
The defective functionality has been returned by defining HAVE_RSA_OAEP_MD
alongside HAVE_CHACHA20_POLY1305, i.e. OpenSSL >= 1.1.0 and NOT libressl.
