did anyone ever need to register online at Bradesco? in PHP I'm presicando of (digitally signed using the PKCS # 7 standard with the RSA 2048 and SHA256 algorithms). In a search on the net I found the function
openssl_pkcs7_sign(realpath("msg.txt"), "signed.txt", 'file://'.realpath('Certificado_A1_2019.pfx'), array ('file://'.realpath('Certificado_A1_2019.pfx'), "3244234234"), array () );
which performs the cryptography of the message, but always returns the message
Warning: openssl_pkcs7_sign (): error getting private key
has anyone had this problem?
