Get public key from .DER file about swiftyrsa HOT 7 CLOSED

@hdoria Thanks for opening an issue! What's the content of error?

from swiftyrsa.

key: (null) - Error Domain=SwiftyRSA.SwiftyRSAError Code=1 "(null)"

from swiftyrsa.

I've created a new Swift project and now I can see the full error:

SwiftyRSAError(message: "Invalid byte at index 18 (51) for public key header"): file /Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-800.0.63/src/swift/stdlib/public/core/ErrorType.swift, line 178

The certificate is below. What am I missing?

certificado.der.zip

@hdoria Got it, you're trying to load a certificate as opposed to a public/private key. To fix this, you'll need to extract the public key with openssl:

openssl x509 -pubkey -noout -in cert.pem  > pubkey.pem

See http://stackoverflow.com/questions/17143606/how-to-save-public-key-from-a-certificate-in-pem-format

Eventually we might want to add public key extraction from a certificate.

I'm still having trouble getting my .der file to be a valid Public Key. How could you do the above command with a .der file, I'm not having any luck. Or better yet, how can I just get the .der file to work in the constructor. I tried both with and without the Bundle parameter (I just used Bundle.main)

@mattbarker016 Any chance you could share this DER file here?

I think I resolved my issue, can you see if it checks out? It's a closed issue from today, July 21.
