💅 ECPKPARAMETERS_PRINT — the OpenSSL girlies' guide

okay bestie, welcome to ECPKPARAMETERS_PRINT(3SSL), a page from the OpenSSL manual. sit down, grab a boba, because these two functions are deprecated and we're gonna talk about them anyway. periodt. 💖

✨ NAME ✨

ECPKParameters_print, ECPKParameters_print_fp — functions for decoding and encoding ASN1 representations of elliptic curve entities 🌀

🎀 SYNOPSIS 🎀

#include <openssl/ec.h>

okay so here's the thing: the following functions have been deprecated since OpenSSL 3.0, and you can hide them entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):

int ECPKParameters_print(BIO *bp, const EC_GROUP *x, int off);
int ECPKParameters_print_fp(FILE *fp, const EC_GROUP *x, int off);

like… they still exist, but they're giving retired-popstar energy. 🫶

🌸 DESCRIPTION 🌸

All of the functions described on this page are deprecated. not me being dramatic — it's literally written right there. Applications should instead use EVP_PKEY_print_params(3). ✨

The ECPKParameters represent the public parameters for an EC_GROUP structure, which represents a curve. 🌈 (yes, a whole curve. main character behavior.)

The ECPKParameters_print() and ECPKParameters_print_fp() functions print a human-readable output of the public parameters of the EC_GROUP to bp or fp. The output lines are indented by off spaces. 🎀 (so off is your little aesthetic indent budget — use it wisely.)

💀 RETURN VALUES 💀

ECPKParameters_print() and ECPKParameters_print_fp() return 1 for success and 0 if an error occurs.

that's it. no in-between. success or flop. 1 or 0. 🍓

and that's the whole page, bestie!! mwah 💋 this was version 4.0.3, dated 2026-09-29, in the OpenSSL 3SSL manual set — literally iconic, no cap. bye bb, go print some params (or, like, use EVP_PKEY_print_params(3) instead, fr fr). 🎀💖✨
