I once used an old Mac OS X in order to extract a Cisco AnyConnect certificate from Keychain that wasn't possible to extract in any other way. https://reverseengineering.stackexchange.com/questions/6043/extract-non-extractable-private-key-from-os-x-keychain/6044#6044 https://reverseengineering.stackexchange.com/questions/6043/... I've first tried recompiling the Keychain app, but it had too many dependencies that were not trivial to build, so, using an older Mac, in that case, was the easiest way to get the private key from my own keychain.
