  4. add algorithms to internal table
  5. =head1 SYNOPSIS
  6. #include <openssl/evp.h>
  7. Deprecated:
  8. # if OPENSSL_API_COMPAT < 0x10100000L
  9. void OpenSSL_add_all_algorithms(void);

  11. void OpenSSL_add_all_digests(void);
  12. void EVP_cleanup(void)
  13. # endif
  14. =head1 DESCRIPTION
  15. OpenSSL keeps an internal table of digest algorithms and ciphers. It uses
  16. this table to lookup ciphers via functions such as EVP_get_cipher_byname().
  17. OpenSSL_add_all_digests() adds all digest algorithms to the table.
  18. OpenSSL_add_all_algorithms() adds all algorithms to the table (digests and
  19. ciphers).
  20. OpenSSL_add_all_ciphers() adds all encryption algorithms to the table including
  21. password based encryption algorithms.
  22. In versions prior to 1.1.0 EVP_cleanup() removed all ciphers and digests from
  23. the table. It no longer has any effect in OpenSSL 1.1.0.
  24. =head1 RETURN VALUES
  25. None of the functions return a value.
  26. =head1 SEE ALSO
  27. L<evp(7)>, L<EVP_DigestInit(3)>,
  28. L<EVP_EncryptInit(3)>
  29. =head1 HISTORY
  30. The OpenSSL_add_all_algorithms(), OpenSSL_add_all_ciphers(),
  31. OpenSSL_add_all_digests(), and EVP_cleanup(), functions
  32. were deprecated in OpenSSL 1.1.0 by OPENSSL_init_crypto() and should
  33. not be used.
