我使用pyOpenSSL
創建X509證書。我需要將此證書導入到Java JKS密鑰庫中,以使其可用於我的Java應用程序。只要我不向證書添加subjectAltName
擴展名,就可以正常工作。如果證書具有替代主體集合,導入到JKS密鑰庫失敗:將subjectAltName(SAN)的X509證書導入JKS密鑰庫

如果我打印在命令行上使用OpenSSL這個證書,我得到這樣的輸出:

這是證書顯然是有效的。根據oracle's documentation,Java 8 keytool應該支持SubjectAlternativeName
擴展。
當我試圖生成密鑰工具本身的一切 - 這似乎工作 - 我注意到,通過密鑰工具生成的證書具有第二擴充X509v3 Subject Key Identifier

我需要這個擴展添加到我的證書也使用pyOpenSSL
。但是,什麼是正確的價值?!
