I'm using the following version: $ openssl version OpenSSL 1.0.1g 7 Apr 2014 Get a certificate openssl s_client -connect outlook.office365.com:443 Loading 'screen' into random state - done CONNECTED(00000274) depth=1 /C=US/O=DigiCert Inc/CN=DigiCert Cloud Services CA-1 verify error:num=20:unable to get local issuer You can verify this using the following command: $ openssl version -d The verification mode can be additionally controlled through 15 flags . 多くのWebサイトがHTTPS化されることで発生するトラブルが「正しくSSL証明書が設定されていない」事によるWebサイトの表示ができないというトラブルです。SSL証明書をインストールしても正しい設定ではない場合、Webブラウザでエラーを表示したり通信に失敗する場合があります。, SSL証明書が正しく反映されたかを確認する方法として、Webブラウザの鍵マークから証明書の情報を表示して確認する方法があります。 この方法で検証した場合とopensslで検証した場合で何が違うでしょうか。, Webブラウザによっては、接続するSSL証明書に記載されている Authority Information Access 拡張フィールドから、必要な中間証明書を自動でインストールする機能を持つものもあります。 これにより有効期限が切れた中間証明書をインストールしていたり、中間証明書のインストールミスがあっても、Webブラウザでは表示されますのでトラブルに気がつきにくいという問題があります。, 全てのWebブラウザが中間証明書の自動インストールに対応しているわけではなく、スマートフォンなどのブラウザではエラーになることがあります。 このため、Webブラウザの鍵マークでの検証ではなく、opensslでの検証をオススメします。, 公開前にSSL証明書のチェインが正しいかを確認するには以下のコマンドを実行します。, コマンドを実行して「OK」が表示されれば証明書のチェインに問題ないことが確認できます。, Webサーバーやメールサーバーに設定した証明書が正しく機能しているか確認するためには、opensslコマンドを使用して次のように実行します。, www.infocircus.jp のSSL証明書を検証した結果は、次のようになります。, 検証で depth=X の表示になっている部分は、証明書のツリーを表しています。 depth=0がオリジナルの証明書、depth=1... とルート証明書までのツリーが確認できます。, 上記の例では、depth=0でCN=www.infocircus.jpとなり、depth=1(1つ上位)でCN = Let's Encrypt Authority X3、depth=2でルート証明書のCN = DST Root CA X3を示しています。, Verify return code が 0(ok)となっていますので、SSL証明書が正しく検証されていることが確認できます。 この Verify return codeが、0(ok)でない場合、SSL証明書の設定に間違いがあるか、指定している証明書が不正の可能性があります。, 実際にSSL証明書の検証に失敗するとどうなるのか、いくつか代表的な例をご紹介いたします。, SSL証明書の有効期限が切れている場合には、Verify return codeで次のようなエラーとなります。, メールサーバーのSMTP(TLS接続)でSSL証明書の確認を行うには、次のコマンドを使用します。, 実際にメールサーバーの証明書を確認した結果が次の通りです。 サンプルのため、サーバー名は変更してあります。, これで、Webサーバー(HTTPS)とメールサーバーのSSL証明書の検証ができました。, if( location.protocol == "https:" ){ 08 December 2018, [{"Business Unit":{"code":"BU053","label":"Cloud & Data Platform"},"Product":{"code":"SS8NDZ","label":"IBM Aspera"},"Component":"","Platform":[{"code":"PF025","label":"Platform Independent"}],"Version":"All Versions","Edition":"","Line of Business":{"code":"","label":""}}]. If we want to validate that a given host has their SSL/TLS certificate trusted by us, we can use the s_client subcommand to perform a verification check (note that you'll need to ^C to exit): $ openssl s_client -connect sub.example.com:443 CONNECTED(00000003) depth=0 CN = sub.example.com verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 CN = sub.example.com verify error:num=27 The Openssl command needs both the certificate chain and the CRL, in PEM format concatenated together for the validation to work. In doing so, we need to tell it which Certificate Authority (CA) to use, which CA key to use, and which Server key to sign. Please try again later or use one of the other support options on this page. We will be using OpenSSL in this article. Follow a example: C:\Program Files\OpenSSL\bin>openssl x509 -noout -modulus -in cs_cert.crt | openssl md5 You can omit the CRL, but then the CRL check will not work, it will just validate the certificate against the chain. Verify certificate chain with OpenSSL Published by Tobias Hofmann on February 18, 2016 February 18, 2016 6 min read A good TLS setup includes providing a complete certificate chain to your clients. cat chain.pem crl.pem > crl_chain.pem openssl verifyコマンドを使用して、サーバ証明書の検証を行います。-CApathには、各CA証明書とリンクが格納されたディレクトリを指定します。 openssl x509 -noout -modulus -in server.crt| openssl md5 openssl rsa -noout -modulus … Compare the output from both commands. The certificate doesn't match the request Resolution You can check if an SSL certificate matches a Private Key by using the 3 easy commands below. $ openssl verify -CApath /dev/null -trusted /etc/ssl/certs It can be useful to check a certificate and key before applying them to your server. To make sure that you have installed the SSL certificate correctly, we have have compiled a cheatsheet with OpenSSL commands to verify that multiple protocols use the correct certificate. [解決方法が見つかりました！] verifyドキュメントから： 独自の発行者である証明書が見つかった場合、その証明書はルートCAであると見なされます。 つまり、ルートCAは検証を機能させるために自己署名する必要があります。これが、2番目のコマンドが機能しなかった理由です。 In order to reduce cluttering of the global manual page namespace, the manual page entries without the 'openssl-' prefix have been deprecated in OpenSSL 3.0 and will be removed in OpenSSL 4.0. Create a Certificate Chain in PEM Format Using OpenSSL Step 6. If they are identical then the private key matches the certificate. Search results are not available at this time. These two commands print out md5 checksums of the certificate and key; the checksums can be compared to verify that the certificate and key match. openssl_verify()は、 pub_key_idが指す公開鍵を使用し、 指定した dataに関して signatureが正しいことを確認します。. openssl_verify( string$data, string$signature, mixed$pub_key_id[, mixed$signature_alg= OPENSSL_ALGO_SHA1] ) : int. -verify_email email Verify if the email matches the email address in Subject Alternative Name or the email in the subject Distinguished Name. For your SSL certificate: openssl x509 –noou t –modulus – in
.crt Once the certificate has been generated, we should verify that it is correct according to the parameters that we have set. document.write ( '
