如何在jwks_uri端点中为OpenID Connect发现返回RSA密钥 [英] How to return RSA key in jwks_uri endpoint for OpenID Connect Discovery

问题描述

在处理OpenID Connect提供程序的发现部分时，我对如何正确返回我的 public keys 感到有些困惑.我的问题特别是与modulus (n)和exponent (e)值有关.

Working on the discovery part of an OpenID Connect provider, I'm a bit confused about how to properly return my public keys. My problem is specifically with the modulus (n) and the exponent (e) values.

两者的初始值为:

n = 124692971944797177402996703053303877641609106436730124136075828918287037758927191447826707233876916396730936365584704201525802806009892366608834910101419219957891196104538322266555160652329444921468362525907130134965311064068870381940624996449410632960760491317833379253431879193412822078872504618021680609253

e = 65537

所以，我在此处，只需对base64url进行编码即可.

So, what I understand reading here, just need to base64url encode both.

(Python示例)

n = urlsafe_b64encode(str(n))
e = urlsafe_b64encode(str(e))

n = "MTI0NjkyOTcxOTQ0Nzk3MTc3NDAyOTk2NzAzMDUzMzAzODc3NjQxNjA5MTA2NDM2NzMwMTI0MTM2MDc1ODI4OTE4Mjg3MDM3NzU4OTI3MTkxNDQ3ODI2NzA3MjMzODc2OTE2Mzk2NzMwOTM2MzY1NTg0NzA0MjAxNTI1ODAyODA2MDA5ODkyMzY2NjA4ODM0OTEwMTAxNDE5MjE5OTU3ODkxMTk2MTA0NTM4MzIyMjY2NTU1MTYwNjUyMzI5NDQ0OTIxNDY4MzYyNTI1OTA3MTMwMTM0OTY1MzExMDY0MDY4ODcwMzgxOTQwNjI0OTk2NDQ5NDEwNjMyOTYwNzYwNDkxMzE3ODMzMzc5MjUzNDMxODc5MTkzNDEyODIyMDc4ODcyNTA0NjE4MDIxNjgwNjA5MjUz"
e = "NjU1Mzc="

我怎么了?例如，因为 Google密钥具有不同的编码.

In what am I wrong? Because, for example, google keys have a different encoding.

(Google键值)

n = "rl1iVsRbhod-gDJj2SDs94lk5iY0QYXV5HIPtjcx4KmIlmq-cdmfLteTeIHFsO5c6hKUt8R3uZzaQNgF3fKt700fT4m6tU23qK4EoLlx9Z_uSajtpMajdmX_FOdyHyQgcn0tj3YqPeYCOTBhRVNoLIenf9vy0hfFy71lcPhylnE",
e = "AQAB"

我错过了什么吗?谢谢您的时间.

Am I missing something? Thanks for your time.

PD:我正在研究的项目.

推荐答案

您正在对值的十进制表示形式进行base64url编码，但是您应该对八位组值进行base64url编码，即，此处定义的big-endian字节序列: https://tools.ietf.org/html/rfc7518#section-6.3.1.1 和此处 https://tools.ietf.org/html/rfc7518#section -2

You're base64url-encoding the decimal representation of the values but you should base64url-encode the octet value, i.e. the big-endian byte sequence as defined here: https://tools.ietf.org/html/rfc7518#section-6.3.1.1 and here https://tools.ietf.org/html/rfc7518#section-2

Base64urlUInt

Base64urlUInt

正整数或零整数表示为 值的无符号big-endian的base64url编码 表示为八位位组序列.八位位组序列必须 利用最少的八位字节数来表示 价值.零表示为BASE64URL(单个零值 八位字节)，即"AA".

The representation of a positive or zero integer value as the base64url encoding of the value's unsigned big-endian representation as an octet sequence. The octet sequence MUST utilize the minimum number of octets needed to represent the value. Zero is represented as BASE64URL(single zero-valued octet), which is "AA".
