💖 X509_SIG_GET0 💖

okay bestie, so this is a page from the OpenSSL manual, section 3SSL — yes, the 3SSL part is the manual name, that's just how the library docs roll, we don't make the rules 💅 and today we're talking about the DigestInfo functions: X509_SIG_get0 and X509_SIG_getm. they're little peek-inside helpers. no cap.

✨ NAME ✨

X509_SIG_get0, X509_SIG_getm — DigestInfo functions 🌸

🎀 SYNOPSIS 🎀

#include <openssl/x509.h>

void X509_SIG_get0(const X509_SIG *sig, const X509_ALGOR **palg,
                   const ASN1_OCTET_STRING **pdigest);
void X509_SIG_getm(X509_SIG *sig, X509_ALGOR **palg,
                   ASN1_OCTET_STRING **pdigest);

🦋 DESCRIPTION 🦋

so X509_SIG_get0() hands you back pointers to the algorithm identifier and the digest value that are sitting inside sig. like, it opens the lil container and points at what's in there 🫶

and X509_SIG_getm() is identical to X509_SIG_get0() except the pointers it gives back are not constant and you can modify them — for example, to initialise them. that's the whole difference. the m is the "you can mess with these" version, fr fr.

👑 RETURN VALUES 👑

X509_SIG_get0() and X509_SIG_getm() return no values. like, literally nothing. they just fill in your pointers, that's it, that's the whole job. it's giving "no thoughts, head empty, output void". 🫠
