as you know, there is no pkcs7 sign in ios, so in backend with nodejs we must convert to pkcs7 for another service call which only accept pkcs7 and it's not in our company. in our sever we have that string which ios sign and certificate and we receive pkcs1 sign from ios , i use node-forge but it does not work in backend I only have certificate and pkcs1 signature, which signs a string text, how can I convert pkcs1 to pkcs7 signature using node js? if there is other solution rather than nodejs, also may help
I tried node-forge, but it want private key which I don't have in server-side, I wanna do this without private key
