在单步操作或多分部流式操作中非对称加密数据。

该接口用于在 AUTOSAR Adaptive Platform 上非对称加密明文数据，并通过提供的智能指针进行管理 [SWS_CRYPT_50174]。在分配了匹配的公钥后，消息既可以在单个处理流程中紧凑转换，也可以通过多分部流式会话连续转换 [SWS_CRYPT_50090]。为了正确执行，必须预先计算缓冲区大小，其中上下文的所有操作均被指定为异常安全和线程安全。

上下文

C++ 类 ara::crypto::cryp::EncryptorPublicCtx 为 AUTOSAR Adaptive Platform 中的非对称数据加密提供了标准化接口。它供客户端应用程序使用非对称公钥加密明文数据。加密密钥的配置既可以直接通过密钥对象（[SWS_CRYPT_50175]）进行，也可以通过对密钥存储位置的引用（KeySlot、[SWS_CRYPT_50086]）进行。数据传递通过高效利用内存的缓冲区区域进行（ReadOnlyMemRegion 用于明文数据，ReadWriteMemRegion 用于密文输出）。

生命周期

上下文的实例通过类型别名 Sptr 中定义的共享指针 std::shared_ptr<EncryptorPublicCtx> 进行管理（[SWS_CRYPT_50174]）。创建本身不属于此接口定义的一部分；推测通过加密架构的上层工厂组件进行实例化。问题 Q-5b7490ba113bb861 (未决)该对象在其生命周期内经历明确定义的状态：

未初始化：实例化后，上下文尚未拥有密钥。在此状态下不允许执行数据处理操作。
已配置（就绪）：通过使用 PublicKey（[SWS_CRYPT_50175]）或 KeySlot（[SWS_CRYPT_50086]）调用 SetKey()，上下文进入就绪状态。在此状态下，既可以执行单步加密，也可以启动流式会话。
流式处理活动：调用 Start()（[SWS_CRYPT_50087]）将上下文置于流式状态。连续的数据块通过 Update()（[SWS_CRYPT_50176]）进行处理。会话要么通过 Finish()（[SWS_CRYPT_50088]）完成，要么通过 Cancel()（[SWS_CRYPT_50089]）中止，从而使上下文返回到已配置状态。

该类的所有方法均被指定为异常安全（exception safe）和线程安全（thread-safe）。如果在流式操作尚未结束时销毁上下文，则底层实现可能会清理分配的缓冲区并隐式丢弃该会话。问题 Q-3eadc946a0bdbdfd (未决)

状态图：上下文从配置到转换的生命周期和状态转换。来源：[SWS_CRYPT_50086]、[SWS_CRYPT_50175]、[SWS_CRYPT_50087]、[SWS_CRYPT_50176]、[SWS_CRYPT_50088]、[SWS_CRYPT_50089]、[SWS_CRYPT_50090]

使用路径

该类支持两种处理模式：用于完整数据集的单步处理和用于分段数据流的多步流式处理。在执行加密之前，应用程序必须考虑缓冲区限制：

通过 GetMinimumChunkSize()` (<a class="spec-record-ref" data-req="SWS_CRYPT_50178">[SWS_CRYPT_50178]</a>) und <code>GetMaximumChunkSize()（[SWS_CRYPT_50091]）可以确定单次调用所支持的最小和最大输入大小。
必须预先使用 GetRequiredOutputBufferSize()（[SWS_CRYPT_50177]）查询输出缓冲区所需的容量。参数 isFinal 在此控制计算是针对中间步骤（false）还是针对最终调用或单步操作（true）进行。

流式加密的典型流程分为以下步骤：

使用有效的 PublicKey（[SWS_CRYPT_50175]）通过 SetKey() 分配密钥。
通过调用 Start()（[SWS_CRYPT_50087]）初始化流式会话。
使用 GetRequiredOutputBufferSize(inputSize, false)（[SWS_CRYPT_50177]）计算中间块所需的输出缓冲区大小。
通过 Update()（[SWS_CRYPT_50176]）重复转换数据块。
确定最后一个块的缓冲区大小（isFinal = true），并通过 Finish()（[SWS_CRYPT_50088]）完成操作。

对于可以在单次处理中完成的紧凑数据，Encrypt()（[SWS_CRYPT_50090]）提供直接的单步调用，而无需划分为启动、更新和完成阶段。

错误场景

所有方法均使用 ara::core::Result 进行错误指示，并在发生错误时保证回滚语义：

状态错误：在未初始化的上下文上调用 Start()、Encrypt() 或 GetRequiredOutputBufferSize() 会导致 ara::crypto::CryptoErrc::kUninitializedContext（[SWS_CRYPT_50087]、[SWS_CRYPT_50090]、[SWS_CRYPT_50177]）。如果在未预先执行 Start() 的情况下调用 Update()、Finish() 或 Cancel()，则操作失败并返回 ara::crypto::CryptoErrc::kProcessingNotStarted（[SWS_CRYPT_50176]、[SWS_CRYPT_50088]、[SWS_CRYPT_50089]）。
密钥和使用错误：如果提供的密钥或 KeySlot 与上下文不兼容，则会报告 ara::crypto::CryptoErrc::kIncompatibleObject（[SWS_CRYPT_50175]、[SWS_CRYPT_50086]、[SWS_CRYPT_50087]、[SWS_CRYPT_50090]）。如果允许的密钥使用规则不包含权限 kAllowDataEncryption，则会导致 ara::crypto::CryptoErrc::kUsageViolation（[SWS_CRYPT_50175]、[SWS_CRYPT_50087]、[SWS_CRYPT_50090]）。如果引用的 KeySlot 为空，则会报告 ara::crypto::CryptoErrc::kEmptyKeySlot（[SWS_CRYPT_50087]、[SWS_CRYPT_50090]）。
缓冲区和数据错误：如果传入的输出缓冲区过小，Encrypt()、Update() 和 Finish() 将响应 ara::crypto::CryptoErrc::kInsufficientCapacity（[SWS_CRYPT_50090]、[SWS_CRYPT_50176]、[SWS_CRYPT_50088]）。与允许的分块大小的偏差会导致 ara::crypto::CryptoErrc::kInvalidInputSize，无效的输入数据会导致 ara::crypto::CryptoErrc::kInvalidArgument。
不支持的功能和资源瓶颈：如果实现不支持流式处理或不支持单步调用，则操作失败并返回 ara::crypto::CryptoErrc::kUnsupported（[SWS_CRYPT_50087]、[SWS_CRYPT_50090]、[SWS_CRYPT_50176]、[SWS_CRYPT_50088]）。当加密资源被占用时，将返回 ara::crypto::CryptoErrc::kBusyResource（[SWS_CRYPT_50087]、[SWS_CRYPT_50090]）。

本指南基于 AUTOSAR Adaptive Platform Release R25-11 的要求，并总结了 ara::crypto::cryp::EncryptorPublicCtx 类的规范。

方法 Cancel() 中止上下文 ara::crypto::cryp::EncryptorPublicCtx 中活动的流式操作，该操作先前通过 Start() 启动且尚未结束 [SWS_CRYPT_50089]。它不接受任何传入参数，并返回一个在成功情况下为空的 ara::core::Result<void> [SWS_CRYPT_50089]。由于该签名直接提供 Result 而非 Future，因此中止可能是同步执行的。问题 Q-cd18e56d693fe1a4 (未决)

错误处理与并发

如果数据处理未事先通过 Start() 启动，则该操作在遵循回滚语义的情况下失败，并带有错误代码 ara::crypto::CryptoErrc::kProcessingNotStarted [SWS_CRYPT_50089]。根据规范，该接口声明为 noexcept，具有异常安全性（exception safe），且针对并发访问被归类为线程安全（thread-safe）[SWS_CRYPT_50089]。

加密栈中的相互作用

通过 Cancel() 实现的中止行为遵循加密模块中有状态流式操作的统一设计模式。具有相同错误语义的类似接口存在于：

SignerPrivateCtx [SWS_CRYPT_50041] 和 VerifierPublicCtx [SWS_CRYPT_50023] 中的签名与验证操作，
SymmetricCipherCtx [SWS_CRYPT_50046] 以及 AuthCipherCtx [SWS_CRYPT_50077] 中的对称与经过身份验证的加密，
DecryptorPrivateCtx [SWS_CRYPT_50069] 中的非对称解密，
MessageAuthnCodeCtx [SWS_CRYPT_50027] 中的消息认证码以及 HashFunctionCtx [SWS_CRYPT_50058] 中的哈希计算。

同步方法 Encrypt 用于在单个调用中加密明文数据（[SWS_CRYPT_50090]）。它从缓冲区 in（ReadOnlyMemRegion）接收输入数据，并将密文写入输出缓冲区 out（ReadWriteMemRegion）（[SWS_CRYPT_50090]）。在成功的情况下，返回值 ara::core::Result<std::size_t> 提供实际写入的输出数据大小，该大小可能小于 out 的总容量（[SWS_CRYPT_50090]）。

在并发性方面，该函数被指定为线程安全（thread-safe）以及异常安全（exception safe）（[SWS_CRYPT_50090]）。

在与上下文 EncryptorPublicCtx 配合使用时，调用前必须注意以下缓冲区边界：

输入大小必须在 [SWS_CRYPT_50178]（GetMinimumChunkSize）和 [SWS_CRYPT_50091]（GetMaximumChunkSize）指定的限制范围内。
输出缓冲区 out 的最大所需容量可预先通过带有参数 isFinal = true 的 GetRequiredOutputBufferSize 进行计算（[SWS_CRYPT_50177]）。

所有错误情况均具有回滚语义（[SWS_CRYPT_50090]）。来自 ara::crypto::CryptoErrc 的已定义错误包括：

kUninitializedContext：未通过提供密钥来初始化上下文（[SWS_CRYPT_50090]）。
kEmptyKeySlot：配置的 KeySlot 为空（[SWS_CRYPT_50090]）。
kIncompatibleObject：密钥类型与变换不匹配（[SWS_CRYPT_50090]）。
kUsageViolation：密钥用途不允许数据加密（kAllowDataEncryption）（[SWS_CRYPT_50090]）。
kInsufficientCapacity：缓冲区 out 过小（[SWS_CRYPT_50090]）。
kInvalidInputSize 或 kInvalidArgument：输入大小不可处理或输入数据无效（[SWS_CRYPT_50090]）。
kUnsupported：不支持单次调用加密（[SWS_CRYPT_50090]）。
kBusyResource：所需资源被占用（[SWS_CRYPT_50090]）。

用法与调用上下文

接口 ara::crypto::cryp::EncryptorPublicCtx（头文件 ara/crypto/cryp/encryptor_public_ctx.h）的纯虚方法 SetKey 用于为非对称加密操作分配密钥[SWS_CRYPT_50086]。类型为 KeySlot::Sptr 的智能指针 keySlot 作为参数传递，其中必须包含一个 PublicKey[SWS_CRYPT_50086]。调用同步进行，并通过空的 ara::core::Result<void> 指示成功。对该语义至关重要的是，存储在槽中的密钥仅在加密启动的时间点才会被提取[SWS_CRYPT_50086]。（解释：由于密钥解析仅在实际加密启动时才进行，因此在此启动时间点之前对槽内容的更新可能仍然有效。）问题 Q-25c5d462aafde8a1 (未决)

错误处理

如果配置失败，将在 Result 对象中返回具有回滚语义的错误码[SWS_CRYPT_50086]：

ara::crypto::CryptoErrc::kIncompatibleObject：当提供的 keySlot 与此上下文不兼容时报告[SWS_CRYPT_50086]。
ara::crypto::CryptoErrc::kUnsupported：当具体上下文实现仅支持直接设置 PublicKey 且不允许通过 KeySlot 进行密钥绑定时出现[SWS_CRYPT_50086]。

并发性与交互

该操作被声明为 noexcept，被指定为异常安全（exception safe），且在并发使用时被指定为线程安全（thread-safe）[SWS_CRYPT_50086]。

通过 KeySlot 进行间接密钥引用的概念以类似方式也存在于其他非对称上下文中，例如 VerifierPublicCtx::SetKey [SWS_CRYPT_50018] 和 KeyEncapsulatorPublicCtx::SetKey [SWS_CRYPT_50012]。它与直接接收密钥对象的方法（例如在 [SWS_CRYPT_24115] 或 [SWS_CRYPT_21815] 中）有所区别。

使用

类ara::crypto::cryp::EncryptorPublicCtx的虚方法SetKey配置上下文以使用提供的公钥[SWS_CRYPT_50175]。\n通过参数key（类型为PublicKey::Sptr）传入用于加密的密钥对象[SWS_CRYPT_50175]。\n执行以同步方式进行并返回一个ara::core::Result<void>，成功时其不包含任何值[SWS_CRYPT_50175]。

错误处理

若配置时发生错误，将报告具有明确回滚语义的相应错误代码[SWS_CRYPT_50175]：

ara::crypto::CryptoErrc::kUsageViolation：密钥的允许用法不允许数据加密（kAllowDataEncryption）[SWS_CRYPT_50175]。
ara::crypto::CryptoErrc::kIncompatibleObject：传入的密钥对象与此加密上下文不兼容[SWS_CRYPT_50175]。
ara::crypto::CryptoErrc::kUnsupported：具体上下文实现仅支持通过KeySlot进行绑定[SWS_CRYPT_50175]。

并发性与限制

该接口定义为noexcept，并指定了既 thread-safe 又 exception safe 的行为[SWS_CRYPT_50175]。\n得益于回滚语义，发生错误时上下文将保持在其先前状态。\nInterpretation：成功的调用应是后续加密操作的必要先决条件，因为上下文在没有分配密钥的情况下无法执行操作。问题 Q-ab4779cac18793fa (未决)

相互作用

该过程遵循非对称上下文的模块级模式，正如在VerifierPublicCtx::SetKey[SWS_CRYPT_24115]和KeyEncapsulatorPublicCtx::SetKey[SWS_CRYPT_21815]中用于密钥绑定一样。\n作为替代，相关接口在配置上也提供了KeySlot变体，例如在VerifierPublicCtx[SWS_CRYPT_50018]或KeyEncapsulatorPublicCtx[SWS_CRYPT_50012]中。

用法与语义

类 ara::crypto::cryp::EncryptorPublicCtx 的纯虚方法 Start 用于初始化新加密的上下文 [SWS_CRYPT_50087]。它不接收任何传入参数并同步执行。作为返回值，该函数提供一个 ara::core::Result<void>，该返回值要么确认成功初始化，要么传递发生的错误代码 [SWS_CRYPT_50087]。

错误处理与回滚行为

如果加密操作所需的前提条件不满足，则调用失败。规范确保了错误情况下的回滚语义，并定义了以下错误原因 [SWS_CRYPT_50087]：

UninitializedContext：未预先向上下文分配密钥。
ara::crypto::CryptoErrc::kEmptyKeySlot：配置的 KeySlot 当前未被占用。
ara::crypto::CryptoErrc::kUsageViolation：密钥的权限不包含使用标志 kAllowDataEncryption。
ara::crypto::CryptoErrc::kIncompatibleObject：分配的密钥类型与所需的变换不兼容。
ara::crypto::CryptoErrc::kBusyResource：初始化所需的资源被占用。
ara::crypto::CryptoErrc::kUnsupported：具体上下文不支持流式处理。

并发性与交互

该方法被指定为 thread-safe 和 exception safe [SWS_CRYPT_50087]。在上下文中提供合适的密钥是成功的必要先决条件。从概念上讲，该函数融入了加密上下文的标准化生命周期中，在这些生命周期中，操作通过无参数调用进行准备——可与签名校验 [SWS_CRYPT_50019]、签名生成 [SWS_CRYPT_50037] 或 MAC 计算 [SWS_CRYPT_22111] 相比。该调用可能是实际执行流加密之前强制性的起始点。问题 Q-db262c3914e6b4cf (未决)

译自德文指南gemini-3.8-flash-low · 2026-10-13 · 德文原文

使用

类ara::crypto::cryp::EncryptorPublicCtx的同步方法Update用于逐步加密明文的数据块[SWS_CRYPT_50176]。通过参数in（ReadOnlyMemRegion）传入明文的一部分，同时加密后的数据被写入输出缓冲区out（ReadWriteMemRegion）[SWS_CRYPT_50176]。作为返回值，该函数通过ara::core::Result<std::size_t>提供实际写入的字节数，该值可能小于out提供的容量[SWS_CRYPT_50176]。

流程与交互

在首次调用Update之前，必须强制通过Start()启动数据处理[SWS_CRYPT_50176]。单次调用允许的最大输入大小可通过方法GetMaximumChunkSize()查询[SWS_CRYPT_50091]。此外，out所需的最小大小可通过GetRequiredOutputBufferSize()计算[SWS_CRYPT_50176]。

错误处理与并发

若执行期间发生错误，将以回滚语义报告该错误[SWS_CRYPT_50176]：

ara::crypto::CryptoErrc::kProcessingNotStarted：此前未通过Start()开始数据处理[SWS_CRYPT_50176]。
ara::crypto::CryptoErrc::kInsufficientCapacity：缓冲区out的容量不足以容纳结果[SWS_CRYPT_50176]。
ara::crypto::CryptoErrc::kInvalidInputSize：in的缓冲区大小无效[SWS_CRYPT_50176]。
ara::crypto::CryptoErrc::kUnsupported：当前上下文不支持流处理[SWS_CRYPT_50176]。

该方法声明为异常安全且线程安全[SWS_CRYPT_50176]。尽管如此，在同一上下文对象上并行调用多个操作大概需要外部同步，以确保加密数据片段的确定性顺序。问题 Q-b22ffe505b583b25 (未决)
