Additional Hash Algorithms for HTTP Instance Digests
HTTP实例摘要的附加哈希算法
Abstract
摘要
The IANA registry named "Hypertext Transfer Protocol (HTTP) Digest Algorithm Values" defines values for digest algorithms used by Instance Digests in HTTP. Instance Digests in HTTP provide a digest, also known as a checksum or hash, of an entire representation of the current state of a resource. This document adds new values to the registry and updates previous values.
名为“超文本传输协议（HTTP）摘要算法值”的IANA注册表定义了HTTP中实例摘要使用的摘要算法的值。HTTP中的实例摘要提供资源当前状态的完整表示的摘要，也称为校验和或哈希。此文档向注册表添加新值并更新以前的值。

The IANA registry named "Hypertext Transfer Protocol (HTTP) Digest Algorithm Values" defines values for digest algorithms used by Instance Digests in HTTP.
名为“超文本传输协议（HTTP）摘要算法值”的IANA注册表定义了HTTP中实例摘要使用的摘要算法的值。
Note: This is unrelated to HTTP Digest Authentication. Instance Digests in HTTP provide a digest, also known as a checksum or hash, of an entire representation of the current state of a resource.
注意：这与HTTP摘要身份验证无关。HTTP中的实例摘要提供资源当前状态的完整表示的摘要，也称为校验和或哈希。
The registry was created by [RFC3230] in 2002. This document adds new values to the registry and updates previous values that had redundant or outdated references.
注册中心由[RFC3230]于2002年创建。此文档向注册表添加新值，并更新具有冗余或过期引用的以前的值。
Example of Instance Digest for SHA-256:
SHA-256的实例摘要示例：
Digest: SHA-256=MWVkMWQxYTRiMzk5MDQ0MzI3NGU5NDEyZTk5OWY1ZGFmNzgyZTJlO
DYzYjRjYzFhOTlmNTQwYzI2M2QwM2U2MQ==
Digest: SHA-256=MWVkMWQxYTRiMzk5MDQ0MzI3NGU5NDEyZTk5OWY1ZGFmNzgyZTJlO
DYzYjRjYzFhOTlmNTQwYzI2M2QwM2U2MQ==
This document makes use of the IANA registry named "Hypertext Transfer Protocol (HTTP) Digest Algorithm Values" specified in [RFC3230].
本文档使用了[RFC3230]中指定的名为“超文本传输协议（HTTP）摘要算法值”的IANA注册表。
Accordingly, IANA has updated the following registrations:
因此，IANA更新了以下注册：
Digest Algorithm: MD5
摘要算法：MD5
Description: The MD5 algorithm, as specified in [RFC1321]. The output of this algorithm is encoded using the base64 encoding [RFC4648].
描述：MD5算法，如[RFC1321]中所述。此算法的输出使用base64编码[RFC4648]进行编码。
Reference: [RFC1321], [RFC4648], this document.
参考文献：[RFC1321]，[RFC4648]，本文件。
Digest Algorithm: SHA
摘要算法：SHA
Description: The SHA-1 algorithm [FIPS-180-3]. The output of this algorithm is encoded using the base64 encoding [RFC4648].
