| 1 | # Crypto Package
|
|---|
| 2 |
|
|---|
| 3 | This package provides cryptographic services that are used to implement firmware
|
|---|
| 4 | features such as UEFI Secure Boot, Measured Boot, firmware image authentication,
|
|---|
| 5 | and network boot. The cryptographic service implementation in this package uses
|
|---|
| 6 | services from the [OpenSSL](https://www.openssl.org/) project and
|
|---|
| 7 | [MbedTLS](https://www.trustedfirmware.org/projects/mbed-tls/) project.
|
|---|
| 8 |
|
|---|
| 9 | EDK II firmware modules/libraries that requires the use of cryptographic
|
|---|
| 10 | services can either statically link all the required services, or the EDK II
|
|---|
| 11 | firmware module/library can use a dynamic Protocol/PPI service to call
|
|---|
| 12 | cryptographic services. The dynamic Protocol/PPI services are only available to
|
|---|
| 13 | PEIMs, DXE Drivers, UEFI Drivers, and SMM Drivers, and only if the cryptographic
|
|---|
| 14 | modules are included in the platform firmware image.
|
|---|
| 15 |
|
|---|
| 16 | There may be firmware image size differences between the static and dynamic
|
|---|
| 17 | options. Some experimentation may be required to find the solution that
|
|---|
| 18 | provides the smallest overall firmware overhead.

|
|---|
| 45 |
|
|---|
| 46 | ## Statically Linking Cryptographic Services
|
|---|
| 47 |
|
|---|
| 48 | The figure below shows an example of a firmware module that requires the use of
|
|---|
| 49 | cryptographic services. The cryptographic services are provided by three library
|
|---|
| 50 | classes called BaseCryptLib, TlsLib, and HashApiLib. These library classes are
|
|---|
| 51 | implemented using APIs from the OpenSSL project that are abstracted by the
|
|---|
| 52 | private library class called OpensslLib. The OpenSSL project implementation
|
|---|
| 53 | depends on C runtime library services. The EDK II project does not provide a
|
|---|
| 54 | full C runtime library for firmware components. Instead, the CryptoPkg includes
|
|---|
| 55 | the smallest subset of services required to build the OpenSSL project in the
|
|---|
| 56 | private library class called IntrinsicLib.
|
|---|
| 57 |
|
|---|
| 58 | The CryptoPkg provides several instances of the BaseCryptLib and OpensslLib with
|
|---|
| 59 | different cryptographic service features and performance optimizations. The
|
|---|
| 60 | platform developer must select the correct instances based on cryptographic
|
|---|
| 61 | service requirements in each UEFI/PI firmware phase (SEC, PEI, DXE, UEFI,
|
|---|
| 62 | UEFI RT, and SMM), firmware image size requirements, and firmware boot
|
|---|
| 63 | performance requirements.

|

| 95 | ## Dynamically Linking Cryptographic Services
|
|---|
| 96 |
|
|---|
| 97 | The figure below shows the entire stack when dynamic linking is used with
|
|---|
| 98 | cryptographic services produced by the CryptoPei, CryptoDxe, or CryptoSmm module
|
|---|
| 99 | through a PPI/Protocol. This solution requires the CryptoPei, CryptoDxe, and
|
|---|
| 100 | CryptoSmm modules to be configured with the set of cryptographic services
|
|---|
| 101 | required by all the PEIMs, DXE Drivers, UEFI Drivers, and SMM Drivers. Dynamic
|
|---|
| 102 | linking is not available for SEC or UEFI RT modules.
|
|---|
| 103 |
|
|---|
| 104 | The EDK II modules/libraries that require cryptographic services use the same
|
|---|
| 105 | BaseCryptLib/TlsLib/HashApiLib APIs. This means no source changes are required
|
|---|
| 106 | to use static linking or dynamic linking. It is a platform configuration option
|
|---|
| 107 | to select static linking or dynamic linking. This choice can be made globally,
|
|---|
| 108 | per firmware module type, or for individual modules.

| 162 | ## Supported Cryptographic Families and Services
|
|---|
| 163 |
|
|---|
| 164 | The table below provides a summary of the supported cryptographic services. It
|
|---|
| 165 | indicates if the family or service is deprecated or recommended to not be used.
|
|---|
| 166 | It also shows which *CryptLib library instances support the family or service.
|
|---|
| 167 | If a cell is blank then the service or family is always disabled and the
|
|---|
| 168 | `PcdCryptoServiceFamilyEnable` setting for that family or service is ignored.
|
|---|
| 169 | If the cell is not blank, then the service or family is configurable using
|
|---|
| 170 | `PcdCryptoServiceFamilyEnable` as long as the correct OpensslLib or TlsLib is
|
|---|
| 171 | also configured.

| 235 | ## Platform Configuration of Cryptographic Services
|
|---|
| 236 |
|
|---|
| 237 | Configuring the cryptographic services requires library mappings and PCD
|
|---|
| 238 | settings in a platform DSC file. This must be done for each of the firmware
|
|---|
| 239 | phases (SEC, PEI, DXE, UEFI, SMM, UEFI RT).
|
|---|
| 240 |
|
|---|
| 241 | The following table can be used to help select the best OpensslLib instance for
|
|---|
| 242 | each phase. The Size column only shows the estimated size increase for a
|
|---|
| 243 | compressed IA32/X64 module that uses the cryptographic services with
|
|---|
| 244 | `OpensslLib.inf` as the baseline size. The actual size increase depends on the
|
|---|
| 245 | specific set of enabled cryptographic services. If ECC services are not
|
|---|
| 246 | required, then the size can be reduced by using OpensslLib.inf instead of
|
|---|
| 247 | `OpensslLibFull.inf`. Performance optimization requires a size increase.
|
|---|
| 248 |
|
|---|
| 249 | | OpensslLib Instance | SSL | ECC | Perf Opt | CPU Arch | Size |

|
|---|
| 257 | ### SEC Phase Library Mappings
|
|---|
| 258 |
|
|---|
| 259 | The SEC Phase only supports static linking of cryptographic services. The
|
|---|
| 260 | following library mappings are recommended for the SEC Phase. It uses the SEC
|
|---|
| 261 | specific version of the BaseCryptLib and the null version of the TlsLib because
|
|---|
| 262 | TLS services are not typically used in SEC.
|
|---|

|---|

|
|---|
| 272 |
|
|---|
| 273 | ### PEI Phase Library Mappings
|
|---|
| 274 |
|
|---|
| 275 | The PEI Phase supports either static or dynamic linking of cryptographic
|
|---|
| 276 | services. The following library mappings are recommended for the PEI Phase. It
|
|---|
| 277 | uses the PEI specific version of the BaseCryptLib and the null version of the
|
|---|
| 278 | TlsLib because TLS services are not typically used in PEI.
|
|---|
| 279 |
|
|---|

|
|---|
| 288 |
|
|---|
| 289 | If dynamic linking is used, then all PEIMs except CryptoPei use the following
|
|---|
| 290 | library mappings. The CryptoPei module uses the static linking settings.

|
|---|
| 307 | ### DXE Phase, UEFI Driver, UEFI Application Library Mappings
|
|---|
| 308 |
|
|---|
| 309 | The DXE/UEFI Phase supports either static or dynamic linking of cryptographic
|
|---|
| 310 | services. The following library mappings are recommended for the DXE/UEFI Phase.
|
|---|
| 311 | It uses the DXE specific version of the BaseCryptLib and the full version of the
|
|---|
| 312 | OpensslLib and TlsLib. If ECC services are not required then a smaller
|
|---|
| 313 | OpensslLib instance can be used.
|
|---|
| 314 |

|
|---|
| 344 |
|
|---|
| 345 | The SMM Phase supports either static or dynamic linking of cryptographic
|
|---|
| 346 | services. The following library mappings are recommended for the SMM Phase. It
|
|---|
| 347 | uses the SMM specific version of the BaseCryptLib and the null version of the
|
|---|
| 348 | TlsLib.
|
|---|
| 349 |

| 378 | ### UEFI Runtime Driver Library Mappings
|
|---|
| 379 |
|
|---|
| 380 | UEFI Runtime Drivers only support static linking of cryptographic services.
|
|---|
| 381 | The following library mappings are recommended for UEFI Runtime Drivers. They
|
|---|
| 382 | use the runtime specific version of the BaseCryptLib and the null version of the
|
|---|
| 383 | TlsLib because TLS services are not typically used at runtime.

| 394 | ### PCD Configuration Settings
|
|---|
| 395 |
|
|---|
| 396 | There are 2 PCD settings that are used to configure cryptographic services.
|
|---|
| 397 | `PcdHashApiLibPolicy` is used to configure the hash algorithm provided by the
|
|---|
| 398 | BaseHashApiLib library instance. `PcdCryptoServiceFamilyEnable` is used to
|
|---|
| 399 | configure the cryptographic services supported by the CryptoPei, CryptoDxe,
|
|---|
| 400 | and CryptoSmm modules.
|
|---|
| 401 |
|
|---|
| 402 | * `gEfiCryptoPkgTokenSpaceGuid.PcdHashApiLibPolicy` - This PCD indicates the
|
|---|
| 403 | HASH algorithm to use in the BaseHashApiLib to calculate hash of data. The
|
|---|
| 404 | default hashing algorithm for BaseHashApiLib is set to HASH_ALG_SHA256.
|
|---|
| 405 | | Setting | Algorithm |
|
|---|
| 406 | |------------|------------------|
|
|---|
| 407 | | 0x00000001 | HASH_ALG_SHA1 |
|
|---|
| 408 | | 0x00000002 | HASH_ALG_SHA256 |
|
|---|
| 409 | | 0x00000004 | HASH_ALG_SHA384 |
|
|---|
| 410 | | 0x00000008 | HASH_ALG_SHA512 |
|
|---|
| 411 | | 0x00000010 | HASH_ALG_SM3_256 |
|
|---|
| 412 |
|
|---|
| 413 | * `gEfiCryptoPkgTokenSpaceGuid.PcdCryptoServiceFamilyEnable` - Enable/Disable
|
|---|
| 414 | the families and individual services produced by the EDK II Crypto
|
|---|
| 415 | Protocols/PPIs. The default is all services disabled. This Structured PCD is
|
|---|
| 416 | associated with the `PCD_CRYPTO_SERVICE_FAMILY_ENABLE` structure that is
|
|---|
| 417 | defined in `Include/Pcd/PcdCryptoServiceFamilyEnable.h`.
|
|---|
| 418 |
|
|---|
| 419 | There are three layers of priority that determine if a specific family or
|
|---|
| 420 | individual cryptographic service is actually enabled in the CryptoPei,
|
|---|
| 421 | CryptoDxe, and CryptoSmm modules.
|
|---|
| 422 |
|
|---|
| 423 | 1) OpensslLib instance selection. When the CryptoPei, CryptoDxe, or CryptoSmm
|
|---|
| 424 | drivers are built, they are statically linked to an OpensslLib library
|
|---|
| 425 | instance. If the required cryptographic service is not enabled in the
|
|---|
| 426 | OpensslLib instance linked, then the service is always disabled.
|
|---|
| 427 | 2) BaseCryptLib instance selection.
|
|---|
| 428 | * CryptoPei is always linked with the PeiCryptLib instance of the
|
|---|
| 429 | BaseCryptLib library class. The table above has a column for the
|
|---|
| 430 | PeiCryptLib. If the family or service is blank, then that family or
|
|---|
| 431 | service is always disabled.
|
|---|
| 432 | * CryptoDxe is always linked with the BaseCryptLib instance of the
|
|---|
| 433 | BaseCryptLib library class. The table above has a column for the
|
|---|
| 434 | BaseCryptLib. If the family or service is blank, then that family or
|
|---|
| 435 | service is always disabled.
|
|---|
| 436 | * CryptoSmm is always linked with the SmmCryptLib instance of the
|
|---|
| 437 | BaseCryptLib library class. The table above has a column for the
|
|---|
| 438 | SmmCryptLib. If the family or service is blank, then that family or
|
|---|
| 439 | service is always disabled.
|
|---|
| 440 | 3) If a family or service is enabled in the OpensslLib instance and it is
|
|---|
| 441 | enabled in the BaseCryptLib instance, then it can be enabled/disabled
|
|---|
| 442 | using `PcdCryptoServiceFamilyEnable`. This structured PCD is associated
|
|---|
| 443 | with the `PCD_CRYPTO_SERVICE_FAMILY_ENABLE` data structure that contains
|
|---|
| 444 | bit fields for each family of services. All of the families are disabled
|
|---|
| 445 | by default. An entire family of services can be enabled by setting the
|
|---|
| 446 | family field to the value `PCD_CRYPTO_SERVICE_ENABLE_FAMILY`. Individual
|
|---|
| 447 | services can be enabled by setting a single service name (bit) to `TRUE`.
|
|---|
| 448 | Settings listed later in the DSC file have priority over settings listed
|
|---|
| 449 | earlier in the DSC file, so it is valid for an entire family to be enabled
|
|---|
| 450 | first and then for a few individual services to be disabled by setting
|
|---|
| 451 | those service names to `FALSE`.
