💖 OpenSSL_add_all_algorithms — the girlies' guide 💖

okay so bestie, you're looking at the OPENSSL_ADD_ALL_ALGORITHMS(3SSL) man page, from the OpenSSL manual set, and honestly? it's a lil bit of a throwback ep. let's get into it 💅

✨ NAME ✨

OpenSSL_add_all_algorithms, OpenSSL_add_all_ciphers, OpenSSL_add_all_digests, EVP_cleanup — add algorithms to internal table 🫶

🌸 SYNOPSIS 🌸

#include <openssl/evp.h>

The following functions have been deprecated since OpenSSL 1.1.0, and can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):

void OpenSSL_add_all_algorithms(void);
void OpenSSL_add_all_ciphers(void);
void OpenSSL_add_all_digests(void);

void EVP_cleanup(void);
not the deprecated era 😭 these are giving "we don't do that anymore" energy, so don't say I didn't warn you.

🦋 DESCRIPTION 🦋

So here's the tea, bestie: OpenSSL keeps an internal table of digest algorithms and ciphers. It uses this table to lookup ciphers via functions such as EVP_get_cipher_byname(). it's like the algorithm catalog, and these functions are the ones stocking the shelves ✨

  • OpenSSL_add_all_digests() adds all digest algorithms to the table.
  • OpenSSL_add_all_algorithms() adds all algorithms to the table (digests and ciphers, both of them, the whole thing, no skips).
  • OpenSSL_add_all_ciphers() adds all encryption algorithms to the table, including password based encryption algorithms.
  • In versions prior to 1.1.0, EVP_cleanup() removed all ciphers and digests from the table. It no longer has any effect in OpenSSL 1.1.0. literally just vibing there doing nothing 💀

👑 RETURN VALUES 👑

None of the functions return a value. not a single one. all void, all mysterious, all "my job here is done" energy 🙈

🔥 SEE ALSO 🔥

go read these if you want the full lore bestie, iykyk ⭐

💜 HISTORY 💜

The OpenSSL_add_all_algorithms(), OpenSSL_add_all_ciphers(), OpenSSL_add_all_digests(), and EVP_cleanup() functions were deprecated in OpenSSL 1.1.0 by OPENSSL_init_crypto() and should not be used.

fr fr, don't use them. OPENSSL_init_crypto() ate and left no crumbs, and the rest is history 🎀

and that's the whole page, bestie 💖 this was version 4.0.3, dated 2026-09-29, from the OPENSSL_ADD_ALL_ALGORITHMS(3SSL) manual — periodt. now go forth and not call these functions 🧚✨
