The HKDF algorithm [RFC5869] is a key derivation function based on the Hashed Message Authentication Code (HMAC). This document assigns algorithm identifiers to the HKDF algorithm when used with three common one-way hash functions. These algorithm identifiers are needed to make use of the HKDF in some security protocols, such as the Cryptographic Message Syntax (CMS) [RFC5652].
HKDF算法[RFC5869]是一个基于哈希消息身份验证码（HMAC）的密钥派生函数。当与三个常见的单向散列函数一起使用时，本文档为HKDF算法分配算法标识符。在某些安全协议中使用HKDF需要这些算法标识符，如加密消息语法（CMS）[RFC5652]。
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.
本文件中的关键词“必须”、“不得”、“必需”、“应”、“不应”、“建议”、“不建议”、“可”和“可选”在所有大写字母出现时（如图所示）应按照BCP 14[RFC2119][RFC8174]所述进行解释。
In this specification, values are generated using ASN.1 [X.680] using the Basic Encoding Rules (BER) and the Distinguished Encoding Rules (DER) [X.690].
在本规范中，使用ASN.1[X.680]，使用基本编码规则（BER）和可分辨编码规则（DER）[X.690]生成值。
This section assigns three algorithm identifiers to HKDF [RFC5869] used with three common one-way hash functions that are specified in [SHS]: SHA-256, SHA-384, and SHA-512. When any of these three object identifiers appear within the ASN.1 type AlgorithmIdentifier, the parameters component of that type SHALL be absent.
本节为HKDF[RFC5869]分配三个算法标识符，并与[SHS]中指定的三个通用单向散列函数一起使用：SHA-256、SHA-384和SHA-512。当这三个对象标识符中的任何一个出现在ASN.1类型算法标识符中时，该类型的参数组件应不存在。
The specification of AlgorithmIdentifier is available in [RFC5911], which evolved from the original definition in X.509 [X.509-88].
[RFC5911]中提供了算法标识符的规范，该规范是从X.509[X.509-88]中的原始定义演变而来的。

Despite the simplicity of HKDF, there are many security considerations that have been taken into account in the design and analysis of this construction. An exposition of all of these aspects is well beyond the scope of this document. Please refer to [EPRINT] for detailed information, including rationale for the HKDF design.
尽管HKDF结构简单，但在设计和分析该结构时，考虑了许多安全因素。对所有这些方面的阐述远远超出了本文件的范围。有关详细信息，包括HKDF设计的基本原理，请参考[EPRINT]。
