### OpenVPN - Make CPassepartoutCryptoOpenSSL agnostic of PassepartoutKit - Move Allocation/ZeroingData from PassepartoutKit to package for internal use - Rename ZeroingData.count to .length for consistency with NSData - Duplicate some Data manipulation code in CryptoOpenSSL - Retain a simplified version of ZeroingData in PassepartoutKit (AutoerasingData) ### WireGuard - Make WireGuardKit imports `internal`
