加密事件分析

管理員可以使用「加密事件分析」取得 Java 安全程式庫所使用之加密演算法的詳細資訊。JMS 將會比較目前使用的演算法與計畫的變更，並標示未來變更或即將到期的憑證可能影響的應用程式。

分析會偵測受管理執行處理中的任何 Java 應用程式是否使用將會變更的演算法、金鑰長度或預設值，並提供建議以避免中斷。

OCI 雲端主控台

以管理員身分登入 OCI 主控台。
開啟導覽功能表，按一下可觀測性與管理，然後按一下 Java 管理下的機組。
選取您的機組。
按一下動作，然後從功能表選取加密事件分析。
按一下開始。
工作要求完成後，請按一下「加密分析」報表。

OCI CLI

執行下列命令：
```
oci jms fleet request-crypto-analyses --fleet-id $FLEET_OCID
```
附註：
加密分析需要執行產生加密相關事件的應用程式，例如 TLS 交握式確認。若要只在特定受管理執行處理上執行加密分析，請使用目標參數，如下方範例所示。

範例

我們將在兩個簡單的 Spring Boot 用戶端 / 伺服器應用程式上示範此功能，這些應用程式將設定弱演算法 SHA1withRSA 的短存憑證，且金鑰大小較弱的 1024 位元。為了簡化，兩個應用程式都會在一個受管理的執行處理上執行。

附註：

範例應用程式可從以下位置擷取：https://github.com/jirkafm/spring-tls-example

#!/usr/bin/env bash
 
# configuration variables
FLEET_OCID=ocid1.jmsfleet.oc1.eu-frankfurt-1.amaaaaaaptiaquqa2qxxkco6hrguz7nyug2hcpgikhe5gz4d7uy6j6ilbtta
MANAGED_INSTANCE_OCID=ocid1.instance.oc1.eu-frankfurt-1.antheljtptiaquqcrjmnu7mxbjthm2jm5qzryu7xy4w27rfo56nxf4uwv6pq
 
# start crypto analysis on specified managed instance
WORK_REQUEST_OCID=$(oci jms fleet request-crypto-analyses \
    --fleet-id "$FLEET_OCID" \
    --targets "[{\"managedInstanceId\":\"$MANAGED_INSTANCE_OCID\"}]" | jq -r '."opc-work-request-id"')
 
echo $WORK_REQUEST_OCID
 
# additionally you can add your own logic to check if work request is finished
# sleep 600
# oci jms work-request get --work-request-id "$WORK_REQUEST_OCID" | jq .data.status

現在我們將執行應用程式，並會對用戶端應用程式進行一些 API 呼叫：

 
$ java -jar spring-tls-client-1.1.0.jar &!
$ java -jar spring-tls-server-1.1.0.jar &!
 
$ BOOK_ID=$(curl -kX POST -H "Content-Type: application/json" -d "{ \"title\": \"AwesomeBook\", \"author\":\"AwesomeAuthor\" }" https://localhost:7081/client/books/ | jq -r '.id')
 
$ curl -k https://localhost:7081/client/books/$BOOK_ID
{"title":"AwesomeBook","author":"AwesomeAuthor","id":"d4131bd9-76f0-48cf-9c33-9089a232c865"}

工作要求完成後，我們可以檢查密碼編譯分析結果：
