ccm_cipher, ccm_dinit, ccm_einit, ccm_generic_auth_decrypt, ccm_generic_auth_encrypt,
ccm_generic_gettag, ccm_generic_setaad, ccm_generic_setiv, ccm_get_ctx_params,
ccm_initctx, ccm_set_ctx_params, ccm_stream_final, ccm_stream_update
gcm_aad_update, gcm_cipher, gcm_cipher_final, gcm_cipher_update
gcm_dinit, gcm_einit, gcm_get_ctx_params, gcm_initctx, gcm_one_shot
gcm_set_ctx_params, gcm_setiv, gcm_stream_final, gcm_stream_update
tdes_dinit, tdes_dupctx, tdes_einit, tdes_freectx
