Support PEM and DER key formats #5
Description
Currently, CryptoKit supports PEM and DER formats only for:
- iOS 14.0+
- macOS 11.0+
- Mac Catalyst 14.0+
- tvOS 14.0+
- watchOS 7.0+
- Xcode 12.0+
It would be nice to have utilities where we can import and export PEM formatted keys. With the newest system versions, this is already possible.
To support "older" system versions, we would need to be able to parse ASN.1 formats. This should be implemented with a ASN.1 decoder/encoder.
