Heimdall is a wrapper around the Security framework for simple encryption/decryption operations.
Fixing the CocoaPods build, also making the build process a bit more stable for CommonCrypto.
This release updates Heimdall to Swift 3.0 syntax.
This change is not backwards compatible, hence the major version number increment.
This change improves the AES encryption logic (by using a non-null IV), whilst also switching over to OAEP padding rather than the PKCS#1 that was used previously.
