Sign XML with OpenSSL in PHP (Solved)?

Question

PHP

Good afternoon!
There is XML, I need to sign it in PKCS#7 format, I use openssl on php.
My code

if (openssl_pkcs7_sign($fileName.'.xml', $fileName.'_signed.xml', "cert.pem",
        array("private.key", "passphrase"),
        array("To" => "[email protected]", // keyed syntax
            "From: [email protected]")
    )) {
       echo 111;
    }

Unity does not display, I do not understand why.
Through the terminal I use this

openssl smime -sign -in file.xml -signer cert.pem -inkey private.key -out file_signed.xml -outform PEM

and after asking for input pass phrase private key errors occur

Googled errors. I didn’t find anything sensible, I didn’t substitute any parameters, I can’t sign it.
Please help, where to dig at least, or if there is a ready-made example.
Thank you!
=====================
I solved the first two errors.
There are two more left.

It turned out that the service sent the wrong certificate.

Answer 1

maybe add a flag -t rsa
