X509_NAME_GET0_DER(3SSL)
β¨ X509_NAME_GET0_DER π
okay bestie, welcome to the OpenSSL corner of the man pages (it's the 3SSL family, iykyk) β today's episode is all about X509_NAME_get0_der, aka the glow-up shortcut for peeking at an X509_NAME's DER encoding without doing a whole copy situation. no cap. π
πΈ NAME πΈ
X509_NAME_get0_der β get X509_NAME DER encoding
π¦ SYNOPSIS π¦
#include <openssl/x509.h>
int X509_NAME_get0_der(const X509_NAME *nm, const unsigned char **pder,
size_t *pderlen);
π DESCRIPTION π
so the tea is this: X509_NAME_get0_der() hands you back an internal pointer to the encoding of an X509_NAME structure, and it drops it right into *pder, with the length being *pderlen bytes. that's it, that's the whole vibe. β¨
it's giving main character energy for applications that wanna examine the encoding of an X509_NAME structure without copying it. no extra malloc, no duplicate bytes, just... look at it. respectfully. π
lowkey important: that pointer is internal. you're borrowing it, not keeping it. the word "internal" is doing a LOT of work here, bestie. π
β RETURN VALUES β
1β success, slay, we ate π0β an error occurred π
