InvalidSignatureException: The request signature we calculated does not match the signature you provided. の解決

Last updated at Posted at 2019-09-03

AWSのアクセスキーによる認証で、以下のエラーが発生して1時間手こずったので備忘録。

InvalidSignatureException: The request signature we calculated does not match the signature you provided. 

原因は、AWSのアクセスキーの発行では、Access Key ID と Secret Access Key が発行されますが、
このとき発行された Secret Access Key が原因でした。

こちらにissueとしてもあがっていました。
https://github.com/aws/aws-cli/issues/602

it is still the case in June 2018 that secrets that have the slash (/) character in them may make the PHP client not work (PHP 7 on Windows 10 in my case), returning the signatures do not match error. In this situation, just generate another pair of keys that is safer.

Secret Access Key にスラッシュ(/)文字が含まれる場合、このエラーが発生することがあるそうです。
Base64のエンコードで問題が発生しているようです。

この状況での解決策は、アクセスキーの再生成です。

issueにも書かれているように、私も別のキーペアを生成し直すことで解決できました。
