Unless otherwise specified: + * - Bignum parameters called \p A, \p B, ... are inputs, and are + * not modified by the function. + * - For operations modulo some number, the modulus is called \p N + * and is input-only. + * - Bignum parameters called \p X, \p Y are outputs or input-output. + * The initial content of output-only parameters is ignored. + * - Some functions use different names that reflect traditional + * naming of operands of certain operations (e.g. + * divisor/dividend/quotient/remainder). + * - \p T is a temporary storage area. The initial content of such + * parameter is ignored and the final content is unspecified. + * - **Bignum sizes**: bignum sizes are always expressed in limbs. + * Most functions work on bignums of a given size and take a single + * \p limbs parameter that applies to all parameters that are limb arrays. + * All bignum sizes must be at least 1 and must be significantly less than + * #SIZE_MAX. The behavior if a size is 0 is undefined. The behavior if the + * total size of all parameters overflows #SIZE_MAX is undefined. + * - **Parameter ordering**: for bignum parameters, outputs come before inputs. + * Temporaries come last. + * - **Aliasing**: in general, output bignums may be aliased to one or more + * inputs. As an exception, parameters that are documented as a modulus value + * may not be aliased to an output. Outputs may not be aliased to one another. + * Temporaries may not be aliased to any other parameter. + * - **Overlap**: apart from aliasing of limb array pointers (where two + * arguments are equal pointers), overlap is not supported and may result + * in undefined behavior. + * - **Error handling**: This is a low-level module. Functions generally do not + * try to protect against invalid arguments such as nonsensical sizes or + * null pointers. Note that some functions that operate on bignums of + * different sizes have constraints about their size, and violating those + * constraints may lead to buffer overflows. + * - **Modular representatives**: functions that operate modulo \p N expect + * all modular inputs to be in the range [0, \p N - 1] and guarantee outputs + * in the range [0, \p N - 1]. If an input is out of range, outputs are + * fully unspecified, though bignum values out of range should not cause + * buffer overflows (beware that this is not extensively tested). + */ + +/* + * Copyright The Mbed TLS Contributors + * SPDX-License-Identifier: Apache-2.0 OR GPL-2.0-or-later + */ + +#ifndef MBEDTLS_BIGNUM_CORE_H +#define MBEDTLS_BIGNUM_CORE_H + +#include "common.h" + +#if defined(MBEDTLS_BIGNUM_C) +#include "mbedtls/bignum.h" +#endif + +#include "constant_time_internal.h" + +#define ciL (sizeof(mbedtls_mpi_uint)) /** chars in limb */ +#define biL (ciL << 3) /** bits in limb */ +#define biH (ciL << 2) /** half limb size */ + +/* + * Convert between bits/chars and number of limbs + * Divide first in order to avoid potential overflows + */ +#define BITS_TO_LIMBS(i) ((i) / biL + ((i) % biL != 0)) +#define CHARS_TO_LIMBS(i) ((i) / ciL + ((i) % ciL != 0)) +/* Get a specific byte, without range checks. */ +#define GET_BYTE(X, i) \ + (((X)[(i) / ciL] >> (((i) % ciL) * 8)) & 0xff) + +/** Count leading zero bits in a given integer. + * + * \warning The result is undefined if \p a == 0 + * + * \param a Integer to count leading zero bits. + * + * \return The number of leading zero bits in \p a, if \p a != 0. + * If \p a == 0, the result is undefined. + */ +size_t mbedtls_mpi_core_clz(mbedtls_mpi_uint a); + +/** Return the minimum number of bits required to represent the value held + * in the MPI. + * + * \note This function returns 0 if all the limbs of \p A are 0. + * + * \param[in] A The address of the MPI. + * \param A_limbs The number of limbs of \p A. + * + * \return The number of bits in \p A. + */ +size_t mbedtls_mpi_core_bitlen(const mbedtls_mpi_uint *A, size_t A_limbs); + +/** Convert a big-endian byte array aligned to the size of mbedtls_mpi_uint + * into the storage form used by mbedtls_mpi. + * + * \param[in,out] A The address of the MPI. + * \param A_limbs The number of limbs of \p A. + */ +void mbedtls_mpi_core_bigendian_to_host(mbedtls_mpi_uint *A, + size_t A_limbs); + +/** \brief Compare a machine integer with an MPI. + * + * This function operates in constant time with respect + * to the values of \p min and \p A. + * + * \param min A machine integer. + * \param[in] A An MPI. + * \param A_limbs The number of limbs of \p A. + * This must be at least 1. + * + * \return MBEDTLS_CT_TRUE if \p min is less than or equal to \p A, otherwise MBEDTLS_CT_FALSE. + */ +mbedtls_ct_condition_t mbedtls_mpi_core_uint_le_mpi(mbedtls_mpi_uint min, + const mbedtls_mpi_uint *A, + size_t A_limbs); + +/** + * \brief Check if one unsigned MPI is less than another in constant + * time. + * + * \param A The left-hand MPI.

The structure must be set up with an + * array of limbs storing the bignum value of the modulus. The modulus must + * be odd and is assumed to have no leading zeroes. The modulus is usually + * named \c N and is usually input-only. Functions which take a parameter + * of type \c const #mbedtls_mpi_mod_modulus* must not modify its value. + * - **Bignum parameters**: Bignums are passed as pointers to an array of + * limbs or to a #mbedtls_mpi_mod_residue structure. A limb has the type + * #mbedtls_mpi_uint. Residues must be initialized before use, and must be + * associated with the modulus \c N. Unless otherwise specified: + * - Bignum parameters called \c A, \c B, ... are inputs and are not + * modified by the function. Functions which take a parameter of + * type \c const #mbedtls_mpi_mod_residue* must not modify its value. + * - Bignum parameters called \c X, \c Y, ... are outputs or input-output. + * The initial bignum value of output-only parameters is ignored, but + * they must be set up and associated with the modulus \c N. Some + * functions (typically constant-flow) require that the limbs in an + * output residue are initialized. + * - Bignum parameters called \c p are inputs used to set up a modulus or + * residue. These must be pointers to an array of limbs. + * - \c T is a temporary storage area. The initial content of such a + * parameter is ignored and the final content is unspecified. + * - Some functions use different names, such as \c r for the residue. + * - **Bignum sizes**: bignum sizes are always expressed in limbs. Both + * #mbedtls_mpi_mod_modulus and #mbedtls_mpi_mod_residue have a \c limbs + * member storing its size. All bignum parameters must have the same + * number of limbs as the modulus. All bignum sizes must be at least 1 and + * must be significantly less than #SIZE_MAX. The behavior if a size is 0 is + * undefined. + * - **Bignum representation**: the representation of inputs and outputs is + * specified by the \c int_rep field of the modulus. + * - **Parameter ordering**: for bignum parameters, outputs come before inputs. + * The modulus is passed after residues. Temporaries come last. + * - **Aliasing**: in general, output bignums may be aliased to one or more + * inputs. Modulus values may not be aliased to any other parameter. Outputs + * may not be aliased to one another. Temporaries may not be aliased to any + * other parameter. + * - **Overlap**: apart from aliasing of residue pointers (where two residue + * arguments are equal pointers), overlap is not supported and may result + * in undefined behavior. + * - **Error handling**: functions generally check compatibility of input + * sizes. Most functions will not check that input values are in canonical + * form (i.e. that \c A < \c N), this is only checked during setup of a + * residue structure. + * - **Modular representatives**: all functions expect inputs to be in the + * range [0, \c N - 1] and guarantee outputs in the range [0, \c N - 1]. + * Residues are set up with an associated modulus, and operations are only + * guaranteed to work if the modulus is associated with all residue + * parameters.

All other + * modules should use the high-level modular bignum interface (bignum_mod.h) + * or the legacy bignum interface (bignum.h). + * + * This is a low-level interface to operations on integers modulo which + * has no protection against passing invalid arguments such as arrays of + * the wrong size. The functions in bignum_mod.h provide a higher-level + * interface that includes protections against accidental misuse, at the + * expense of code size and sometimes more cumbersome memory management. + * + * The functions in this module obey the following conventions unless + * explicitly indicated otherwise: + * - **Modulus parameters**: the modulus is passed as a pointer to a structure + * of type #mbedtls_mpi_mod_modulus. The structure must be set up with an + * array of limbs storing the bignum value of the modulus. The modulus must + * be odd and is assumed to have no leading zeroes. The modulus is usually + * named \c N and is usually input-only. + * - **Bignum parameters**: Bignums are passed as pointers to an array of + * limbs. A limb has the type #mbedtls_mpi_uint. Unless otherwise specified: + * - Bignum parameters called \c A, \c B, ... are inputs, and are not + * modified by the function. + * - Bignum parameters called \c X, \c Y are outputs or input-output. + * The initial content of output-only parameters is ignored. + * - \c T is a temporary storage area. The initial content of such a + * parameter is ignored and the final content is unspecified. + * - **Bignum sizes**: bignum sizes are usually expressed by the \c limbs + * member of the modulus argument. All bignum parameters must have the same + * number of limbs as the modulus. All bignum sizes must be at least 1 and + * must be significantly less than #SIZE_MAX. The behavior if a size is 0 is + * undefined. + * - **Bignum representation**: the representation of inputs and outputs is + * specified by the \c int_rep field of the modulus for arithmetic + * functions. Utility functions may allow for different representation. + * - **Parameter ordering**: for bignum parameters, outputs come before inputs. + * The modulus is passed after other bignum input parameters. Temporaries + * come last. + * - **Aliasing**: in general, output bignums may be aliased to one or more + * inputs. Modulus values may not be aliased to any other parameter. Outputs + * may not be aliased to one another. Temporaries may not be aliased to any + * other parameter. + * - **Overlap**: apart from aliasing of limb array pointers (where two + * arguments are equal pointers), overlap is not supported and may result + * in undefined behavior. + * - **Error handling**: This is a low-level module. Functions generally do not + * try to protect against invalid arguments such as nonsensical sizes or + * null pointers. Note that passing bignums with a different size than the + * modulus may lead to buffer overflows. Some functions which allocate + * memory or handle reading/writing of bignums will return an error if + * memory allocation fails or if buffer sizes are invalid. + * - **Modular representatives**: all functions expect inputs to be in the + * range [0, \c N - 1] and guarantee outputs in the range [0, \c N - 1]. If + * an input is out of range, outputs are fully unspecified, though bignum + * values out of range should not cause buffer overflows (beware that this is + * not extensively tested). + */ + +/* + * Copyright The Mbed TLS Contributors + * SPDX-License-Identifier: Apache-2.0 OR GPL-2.0-or-later + */ + +#ifndef MBEDTLS_BIGNUM_MOD_RAW_H +#define MBEDTLS_BIGNUM_MOD_RAW_H + +#include "common.h" + +#if defined(MBEDTLS_BIGNUM_C) +#include "mbedtls/bignum.h" +#endif + +#include "bignum_mod.h" + +/** + * \brief Perform a safe conditional copy of an MPI which doesn't reveal + * whether the assignment was done or not. + * + * The size to copy is determined by \p N. + * + * \param[out] X The address of the destination MPI. + * This must be initialized.
