Crash on macOS 10.15 Catalina due to libcrypto loading

[piger]

Loading the unversioned libcrypto library will crash the Python process on macOS 10.15 Catalina:

pychef/chef/rsa.py

Lines 6 to 9 in 216cbb2

	if sys.platform == 'win32' or sys.platform == 'cygwin':
	_eay = CDLL('libeay32.dll')
	else:
	_eay = CDLL(find_library('crypto'))

The crash dialog shows:

Application Specific Information:
/usr/lib/libcrypto.dylib
abort() called
Invalid dylib load. Clients should not load the unversioned libcrypto dylib as it does not have a stable ABI.

Hi as a "quick and dirty" fix you can do the following:
brew install openssl
and change the CDLL(find_library('crypto')) to CDLL('/usr/local/Cellar/openssl@1.1/1.1.1d/lib/libssl.1.1.dylib')
