How to generate a valid key.pem to test the workflow? #6

Closed liuxuan30 closed 4 years ago

liuxuan30 commented 4 years ago

I tried to create key.pem following https://github.com/starkbank/ecdsa-python:

openssl ecparam -name secp256k1 -genkey -out privateKey.pem
openssl ec -in privateKey.pem -pubout -out publicKey.pem

and then rename privateKey.pem to key.pem next to the server py file.

however when running showing ads, it throws:

it seems it failed to read public key? please fix and maybe add a doc about this. thank you

你找到什么办法了吗？我也在苦苦探索同样的问题·······

danielxt7 commented 4 years ago

Hey @liuxuan30 & @Treagzhao - we wrote skadnetwork_server to work with keys compatible with what Apple is issuing for adnetworks registering for SKAdNetwork - Apple are using a different ecdsa curve: prime256v1. so please generate the key this way:

openssl ecparam -name prime256v1 -genkey -out privateKey.pem

we have tried ,but the prime256v1 has a param head like this

-----BEGIN EC PARAMETERS----- BgUrgQQACg== -----END EC PARAMETERS-----

and the python server could not read this ,it occurs an error. How can I fix this?

actually, you can workaround by not passing the key so it will generate the key pair for you
