💅 ASN1_STRING_TABLE_ADD(3ossl) — like, the whole ASN1_STRING_TABLE situation, explained

okay so bestie, gather round, because we're talking about the 3ossl manual page for ASN1_STRING_TABLE, ASN1_STRING_TABLE_add, ASN1_STRING_TABLE_get, and ASN1_STRING_TABLE_cleanup — aka the ASN1_STRING_TABLE manipulation functions 🎀 no cap, it's giving "tiny table, big feelings."

🌸 NAME 🌸

ASN1_STRING_TABLE, ASN1_STRING_TABLE_add, ASN1_STRING_TABLE_get, ASN1_STRING_TABLE_cleanup — the ASN1_STRING_TABLE manipulation functions, periodt. 💖

✨ SYNOPSIS ✨

#include <openssl/asn1.h>

typedef struct asn1_string_table_st ASN1_STRING_TABLE;

int ASN1_STRING_TABLE_add(int nid, long minsize, long maxsize,
                          unsigned long mask, unsigned long flags);
ASN1_STRING_TABLE *ASN1_STRING_TABLE_get(int nid);
void ASN1_STRING_TABLE_cleanup(void);

like, that's the whole vibe right there 🫶 copy it exactly, don't come for me.

🦋 DESCRIPTION 🦋

🎀 Types

ASN1_STRING_TABLE is a table which holds string information (basically minimum size, maximum size, type and etc) for a NID object. that's it, that's the girl. she's a little lookup table and she's thriving 💅

💜 Functions

  • ASN1_STRING_TABLE_add() — adds a new ASN1_STRING_TABLE item into the local ASN1 string table based on the nid along with other parameters. lowkey iconic behavior honestly ✨

If the item is already in the table, fields of ASN1_STRING_TABLE are updated (depending on the values of those parameters, e.g., minsize and maxsize >= 0, mask and flags != 0). If the nid is standard, a copy of the standard ASN1_STRING_TABLE is created and updated with other parameters. so she doesn't wreck the original, she makes a copy first — main character energy with boundaries 🌈

  • ASN1_STRING_TABLE_get() — searches for an ASN1_STRING_TABLE item based on nid. It will search the local table first, then the standard one. local girlies first, always 🙈
  • ASN1_STRING_TABLE_cleanup() — frees all ASN1_STRING_TABLE items added by ASN1_STRING_TABLE_add(). she's the friend who shows up with a trash bag after the party 🧹💀

👑 RETURN VALUES 👑

  • ASN1_STRING_TABLE_add() returns 1 on success, 0 if an error occurred. binary queen, no in-between 🍓
  • ASN1_STRING_TABLE_get() returns a valid ASN1_STRING_TABLE structure or NULL if nothing is found. NULL is the "she's not here, girl" of return values 😭
  • ASN1_STRING_TABLE_cleanup() does not return a value. she gives nothing and that's on purpose 💅
