Create Apple Developer p12 signing Identity from Windows

Before starting you'll need to install OpenSSL.

  1. Generate an RSA key (or use an existing one):

    openssl genrsa -out keyname.key 2048

  2. Create a certificate signing request (skip all question fields but Country Name, Common Name and Email Address).

    1. openssl req -new -key keyname.key -out CertificateSigningRequest.certSigningRequest

    2. Upload it to Apple Developer portal and download the new Certificate.

  3. Transcode Certificate to PEM format

    openssl x509 -in ios_development.cer -inform DER -out ios_development.pem -outform PEM

  4. Create p12 from PEM. You must set a password to avoid errors when using it in some CI systems like Bitrise.

    openssl pkcs12 -export -inkey keyname.key -in ios_development.pem -out ios_development.p12
