Fwd: Create a signed file from detached signature and clear file content

[Antonio Iacono <antiac@xxxxxxxxx>]

Hi,
assuming I have the following:
- data.txt
- data.p7s (the detached signature)

Can I generate the bundled (p7m) signed file ?

I tried:

content = BIO_new_file("data.txt", "rb");
signature = BIO_new_file("data.p7s", "rb");
p7 = d2i_PKCS7_bio(signature, NULL);
PKCS7_set_detached(p7, 0);
bundled = BIO_new_file("bundled.p7m", "wb");
i2d_PKCS7_bio_stream(bundled, p7, content, 0);

but the generated file (bundled.p7m) is identical to the signature file (data.p7s)

Thanks,

Antonio
