O2I_SCT_LIST(3ossl)

📦 version 3.5.0, in opensuse-leap 16.0

✨ NAME ✨

okay so bestie, welcome to the O2I_SCT_LIST(3ossl) manual page — yes, that’s the 3ossl manual — and it’s serving decode and encode realness for Signed Certificate Timestamp lists in TLS wire format. 💅

The whole squad is o2i_SCT_LIST, i2o_SCT_LIST, o2i_SCT, and i2o_SCT. They decode and encode Signed Certificate Timestamp lists in TLS wire format. Periodt. 🎀

🛠️ SYNOPSIS 🛠️

#include <openssl/ct.h>

STACK_OF(SCT) *o2i_SCT_LIST(STACK_OF(SCT) **a, const unsigned char **pp,
                            size_t len);
int i2o_SCT_LIST(const STACK_OF(SCT) *a, unsigned char **pp);
SCT *o2i_SCT(SCT **psct, const unsigned char **in, size_t len);
int i2o_SCT(const SCT *sct, unsigned char **out);

💅 DESCRIPTION 💅

The SCT_LIST and SCT functions are very similar to the i2d and d2i family of functions, except that they convert to and from TLS wire format, as described in RFC 6962. It’s giving “same family energy, different wire-format fit.” 🦋

And if you want the tea on how the parameters are treated and what the return values are, go peek at d2i_SCT_LIST(3) — it’s all there, bestie. 👑

🫶 RETURN VALUES 🫶

All of the functions have return values consistent with those stated for d2i_SCT_LIST(3) and i2d_SCT_LIST(3). That’s the return-value lore, no cap. ☕
