I am having the most difficult time trying to figure out the process for just getting my development .p12 figured out. Full disclosure, being a windows user does not make my life any easier. Seems fairly straightforward on a mac (which I do not have) So I thought I would come here and see if I could collect information on getting working certs and keys on windows pc. Here's what I have so far: -OpenSSL -openssl req -nodes -newkey rsa:2048 -keyout private_key.key -out cer_sign_request.csr Generates a key and a sign request. went to dev portal submit CSR --> recieved CER -back to OpenSSL -openssl x509 -in ios_development.cer -inform DER -out ios_development.pem -outform PEM CER-->PEM -openssl pkcs12 -export -inkey keyname.key -in ios_development.pem -out ios_development.p12 -"No cert in -in file 'ios_development.pem' matches private key" so here I am. Lost. Mind you I've tried the process in a few different ways and now I am on a mission to find my "private_key" somehow with no way to access keychain. I dunno feels convuluted. for good reason I am sure. If anyone has a streamlined version of how to get this done I will be forever indebted to you. Your time is greatly appreciated. for futher context I am just trying to get an eas build on my phone from expo. Thankyou!
