This is only 45useful with fetched B<EVP_CIPHER>s. 46 47=item evp_kdf_get_number() 48 49Keturns the internal dynamic number assigned to I<kdf>. 50 51=item evp_kem_get_number() 52 53Returns the internal dynamic number assigned to I<kem>. 54 55=item evp_keyexch_get_number() 56 57Returns the internal dynamic number assigned to the I<exchange>. 58 59=item evp_keymgmt_get_number() 60 61Returns the internal dynamic number assigned to the I<keymgmt>. 62 63=item evp_mac_get_number() 64 65Returns the internal dynamic number assigned to I<mac>. 66 67=item evp_md_get_number() 68 69Returns the internal dynamic number assigned to the I<md>. This is 70only useful with fetched B<EVP_MD>s. 71 72=item evp_rand_get_number() 73 74Returns the internal dynamic number assigned to I<rand>. 75 76=item evp_signature_get_number() 77 78Returns the internal dynamic number assigned to I<signature>. 79 80=item ossl_decoder_get_number() 81 82Returns the internal dynamic number assigned to the given I<decoder>. 83 84=item ossl_encoder_get_number() 85 86Returns the internal dynamic number assigned to the given I<encoder>. 87 88=item ossl_store_loader_get_number() 89 90Returns the internal dynamic number assigned to the given I<loader>. 91 92=back 93 94=head1 RETURN VALUES 95 96All of these functions return the provider specific identification number 97for the specified algorithm. 98 99=head1 HISTORY 100 101This functionality was added to OpenSSL 3.0. 102 103=head1 COPYRIGHT 104 105Copyright 2021 The OpenSSL Project Authors.
