Hello!

I am want to create new merchant ID, so I did all necessary actions on the developer portal and now I am trying to create certificate via sending certificate signing request and getting the following error:

CSR algorithm/size incorrect. Expected: ECC(256)

So, I went to certificate signing reqest manager and set tick to "Let me specify key pair information" , where I manually set ECC (256) algorithm.

Thus did same things as here Unable to create a Merchant ID Certificate from an ECC 256 certificate signing request , but selected ECC 256 which is required.

Then I tried again, but I am getting same error.

CSR algorithm/size incorrect. Expected: ECC(256)

Can you help me with this? Can't it be an issues of new UI ?

P.S.: I have tried all algorithms, just in case.

Hi,

The issue dissapeared after some time for me (hour or so). You can try again now, I guess.

The Certificate Signing Request for the Merchant Identity Certificate requires the RSA-2048 algorithm. As an alternative, you can use openSSL to generate the CSR via the following steps:

Execute the following openSSL command to create a private key:

openssl genrsa -out privateKey.key 2048

Execute the following openSSL command to generate a certificate signing request (CSR) from the private key:

openssl req -new -key privateKey.key -out certificateSigningRequest.csr

Login to the Apple Developer Portal and upload the CSR file. You can then download the newly generated certificate.
