The following functions have been deprecated since OpenSSL 3.0, and can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):
int DH_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func, CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func); int DH_set_ex_data(DH *type, int idx, void *arg); void *DH_get_ex_data(DH *type, int idx); int DSA_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func, CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func); int DSA_set_ex_data(DSA *type, int idx, void *arg); void *DSA_get_ex_data(DSA *type, int idx); int EC_KEY_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func, CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func); int EC_KEY_set_ex_data(EC_KEY *type, int idx, void *arg); void *EC_KEY_get_ex_data(EC_KEY *type, int idx); int RSA_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func, CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func); int RSA_set_ex_data(RSA *type, int idx, void *arg); void *RSA_get_ex_data(RSA *type, int idx); int RSA_set_app_data(RSA *type, void *arg); void *RSA_get_app_data(RSA *type); int ENGINE_get_ex_new_index(long argl, void *argp, CRYPTO_EX_new *new_func, CRYPTO_EX_dup *dup_func, CRYPTO_EX_free *free_func); int ENGINE_set_ex_data(ENGINE *type, int idx, void *arg); void *ENGINE_get_ex_data(ENGINE *type, int idx);
All functions with a TYPE of DH, DSA, RSA and EC_KEY are deprecated. Applications should instead use EVP_PKEY_set_ex_data(), EVP_PKEY_get_ex_data() and EVP_PKEY_get_ex_new_index().
All functions with a TYPE of ENGINE are deprecated. Applications using engines should be replaced by providers.
These functions handle application-specific data for OpenSSL data structures.
TYPE_get_ex_new_index() is a macro that calls CRYPTO_get_ex_new_index() with the correct index value.
TYPE_set_ex_data() is a function that calls CRYPTO_set_ex_data() with an offset into the opaque exdata part of the TYPE object.
TYPE_get_ex_data() is a function that calls CRYPTO_get_ex_data() with an offset into the opaque exdata part of the TYPE object.
For compatibility with previous releases, the exdata index of zero is reserved for ``application data.'' There are two convenience functions for this. TYPE_set_app_data() is a macro that invokes TYPE_set_ex_data() with idx set to zero. TYPE_get_app_data() is a macro that invokes TYPE_get_ex_data() with idx set to zero.
TYPE_set_ex_data() returns 1 on success or 0 on error.
TYPE_get_ex_data() returns the application data or NULL if an error occurred.
