RSA example doesn't compile

[leo150]

Getting an error while trying to use methods that are declared public with an extension.
I use main branch to get RSA support.

Steps to reproduce the issue:

1. Create fresh iOS project
2. Add CryptoSwift pod: pod 'CryptoSwift', :git => '[email protected]:krzyzanowskim/CryptoSwift.git'
3. Try to use any "public" method let rsa = try? RSA(rawRepresentation: Data())
4. Get a random error: Incorrect argument label in call (have 'rawRepresentation:', expected 'keySize:')

Using other methods that were declared public with an extension has the same result:

let rsa = try? RSA(keySize: 0)
try? rsa.externalRepresentation() // No exact matches in call to instance method 'externalRepresentation'

Might be related to Swift 5.7

Is there any workaround? Thanks

Looks like it's this commit that made DEREncodable internal so public methods aren't visible anymore.
@btoms20 could you please take a look?

Thanks for catching this! Not sure why I switched everything back to internal. I'm more than happy to make the DEREncodable and DERDecodable protocols and their associated methods public again.

@nathanfallet, do you think we should open up the entirety of the DERCodable API or should we selectively open some methods and initializers (in order to keep the public facing API cleaner and more straight forward)?

/// Keep these internal 
internal init(publicDER: Array<UInt8>) throws
internal init(privateDER: Array<UInt8>) throws

/// Make this public
public init(rawRepresentation: Data) throws

Same with the exports...

/// Keep these internal
internal func publicKeyDER() throws -> Array<UInt8>
internal func privateKeyDER() throws -> Array<UInt8>

/// Make these public
public func externalRepresentation() throws -> Data
public func publicKeyExternalRepresentation() throws -> Data

Let me know what you prefer and I'll draft up a PR...

[nathanfallet]

The main goal of the library is to expose cryptographic features. However, this protocol cab be useful to be used. So making it public allows it to be used.
Mention me on the PR and I'll be happy to merge it!

@leo150 - #981 should fix this 👍

Thank you!
