|  | * | 
|  | * The bignum code uses double-width division to speed up some operations. | 
|  | * Double-width division is often implemented in software that needs to | 
|  | * be linked with the program. The presence of a double-width integer | 
|  | * type is usually detected automatically through preprocessor macros, | 
|  | * but the automatic detection cannot know whether the code needs to | 
|  | * and can be linked with an implementation of division for that type. | 
|  | * By default division is assumed to be usable if the type is present. | 
|  | * Uncomment this option to prevent the use of double-width division. | 
|  | * | 
|  | * Note that division for the native integer type is always required. | 
|  | * Furthermore, a 64-bit type is always required even on a 32-bit | 
|  | * platform, but it need not support multiplication or division. In some | 
|  | * cases it is also desirable to disable some double-width operations. For |

|  | * alternative. | 
|  | * | 
|  | * The original implementation can in addition be removed by setting the | 
|  | * MBEDTLS_ECP_NO_FALLBACK option, in which case any function for which the | 
|  | * corresponding MBEDTLS_ECP__FUNCTION_NAME__ALT macro is defined will not be | 
|  | * able to fallback to curves not supported by the alternative implementation. | 
|  | * | 
|  | * Any of these options become available by defining MBEDTLS_ECP_INTERNAL_ALT |

|  | * The mbedtls_internal_ecp_grp_capable function should return 1 if the | 
|  | * replacement functions implement arithmetic for the given group and 0 | 
|  | * otherwise. | 
|  | * The functions mbedtls_internal_ecp_init and mbedtls_internal_ecp_free are | 
|  | * called before and after each point operation and provide an opportunity to | 
|  | * implement optimized set up and tear down instructions. | 
|  | * | 
|  | * Example: In case you set MBEDTLS_ECP_INTERNAL_ALT and | 
|  | * MBEDTLS_ECP_DOUBLE_JAC_ALT, mbed TLS will still provide the ecp_double_jac() | 
|  | * function, but will use your mbedtls_internal_ecp_double_jac() if the group | 
|  | * for the operation is supported by your implementation (i.e. your | 
|  | * mbedtls_internal_ecp_grp_capable() function returns 1 for this group). If the | 
|  | * group is not supported by your implementation, then the original mbed TLS | 
|  | * implementation of ecp_double_jac() is used instead, unless this fallback | 
|  | * behaviour is disabled by setting MBEDTLS_ECP_NO_FALLBACK (in which case | 
|  | * ecp_double_jac() will return MBEDTLS_ERR_ECP_FEATURE_UNAVAILABLE). | 
|  | * | 
|  | * The function prototypes and the definition of mbedtls_ecp_group and |

|  | * This pair of functions allows one side of a connection to serialize the | 
|  | * context associated with the connection, then free or re-use that context | 
|  | * while the serialized state is persisted elsewhere, and finally deserialize | 
|  | * that state to a live context for resuming read/write operations on the | 
|  | * connection. From a protocol perspective, the state of the connection is | 
|  | * unaffected, in particular this is entirely transparent to the peer. |

|  | * Note: this is distinct from TLS session resumption, which is part of the |

|  | * establishing new connections associated to a saved session with shorter, | 
|  | * lighter handshakes, while context serialization is a local optimization in | 
|  | * handling a single, potentially long-lived connection. |

|  | * versions of the C language standards do not provide a secure implementation | 
|  | * of memset(). Therefore, MBEDTLS_PLATFORM_ZEROIZE_ALT enables users to | 
|  | * configure their own implementation of mbedtls_platform_zeroize(), for | 
|  | * example by using directives specific to their compiler, features from newer |
