+
+为什么没有 MD5？
+Java 8+ 默认禁用了 MD5（出于安全原因），keytool 默认只显示 SHA-1 和 SHA-256。
+
+但 证书本身仍然可以计算 MD5，只是 keytool 默认不显示。
+
+如何获取该 Keystore 的 MD5 指纹？
+方法 1：使用 openssl 计算证书的 MD5
+导出证书（.cer 或 .pem 格式）：
+
+bash
+keytool -exportcert -alias ai_jlyh_app -keystore ai_jlyh_app.keystore -file cert.cer
+（输入 keystore 密码）
+
+用 openssl 计算 MD5 指纹：
+
+bash
+openssl x509 -inform der -in cert.cer -noout -fingerprint -md5
+输出示例：
+
+text
+MD5 Fingerprint=D5:DC:64:CD:DD:A5:25:FE:26:B8:EF:24:8A:2B:B3:89
+去掉冒号，转为小写，就是备案所需的 d5dc64cddda525fe26b8ef248a2bb389。
