この方法では、暗号化されたパスワードを設定ファイル内に保存する必要がないので、不正な第三者による検索や復号化が困難となってセキュリティが強化されます。

パスワードを暗号化する

In this method, you’ll use AlgorithmCipher that allows you to choose the algorithm used to encrypt the sensitive information in the bitbucket.properties file.

Before you begin: Prepare the JSON object

You’ll need to provide all arguments required to encrypt the sensitive data in a JSON object. Prepare beforehand by using the information and examples below.

Using this information, prepare the appropriate JSON for the sensitive data to be encrypted, for example:

{"plainTextPassword":"secret","algorithm":"AES/CBC/PKCS5PADDING","algorithmKey":"AES"}

以下の手順を実行するときは、この JSON を使用できるようにしておいてください。

Step 1. Encrypt the sensitive data

データベースのパスワードを暗号化するときは、以下のテーブルに示すように、いくつかのオプションの引数を指定できます。

To encrypt the database password, follow the steps below.

1. <Bitbucket-installation-directory>/tools/atlassian-password に移動します。

2. 次のコマンドを実行して、データベース パスワードを暗号化します。上記のオプション パラメーターも使用できます。

   java -cp "./*" com.atlassian.secrets.cli.db.DbCipherTool -c com.atlassian.secrets.store.algorithm.AlgorithmSecretStore

   When prompted for a password enter the prepared JSON object based on the information from Before you begin.
   Note: the JSON object must be entered as a single line.
   When this command runs successfully, you will see output similar to the output below:

When encrypting your data, the encryption tool generates three files and prints the output JSON object that you'll later add to the bitbucket.properties file. The next step discusses how to secure those files. 

ステップ 2. 生成されたファイルを保護する

パスワードを暗号化すると、3 つのファイルが生成されます。

• javax.crypto.SealedObject_[timestamp]
  暗号化されたパスワードを含むファイル。

• javax.crypto.spec.SecretKeySpec_[timestamp] 
  パスワードの暗号化に使用されたキー。このファイルは、パスワードを復号化するために必要です。

• java.security.AlgorithmParameters_[timestamp]
  The algorithm parameters used to encrypt your password. You will need this file only if you want to recreate an encrypted password. 

If you're running Bitbucket in a cluster, the files should be available to all nodes via the same path. Bitbucket needs to be able to access and read those files to decrypt your password and connect to the database.

1. ツールによって生成されたファイルを安全な場所に移動します。
2. Change them to read-only and accessible only to the user running Bitbucket.

Step 3. Add the encrypted data to bitbucket.properties

To add the encrypted data:

1. <home-directory>/shared/bitbucket.properties ファイルをバックアップします。バックアップをインスタンスの外部の安全な場所に移動します。

2. In the bitbucket.properties file, add or modify the encrypted-property.cipher.classname property to contain:

   com.atlassian.secrets.store.algorithm.AlgorithmSecretStore

3. In the bitbucket.properties file, add or modify the jdbc.password property to contain the fully qualified path to the two files prefixed with {ENC}:

   {ENC}{"sealedObjectFilePath":"/home/bitbucket/javax.crypto.SealedObject_1234567890","keyFilePath":"/home/bitbucket/javax.crypto.spec.SecretKeySpec_1234567890"}

4. Once updated, check that the bitbucket.properties contains:

   encrypted-property.cipher.classname=com.atlassian.secrets.store.algorithm.AlgorithmSecretStore
   jdbc.password={ENC}{"sealedObjectFilePath":"/home/bitbucket/javax.crypto.SealedObject_1234567890","keyFilePath":"/home/bitbucket/javax.crypto.spec.SecretKeySpec_1234567890"}

5. Restart Bitbucket.

Decrypt the sensitive data

機密データを復号化する方法。

1. Extend the command used earlier with the -m decrypt parameter:

   java -cp "./*" com.atlass ian.secrets.cli.db.DbCipherTool -c com.atlassian.secrets.store.algorithm.AlgorithmSecretStore -m decrypt

2. When asked for a password, provide the JSON object from your bitbucket.properties file without the {ENC} prefix. 
   

   {"sealedObjectFilePath":"/home/bitbucket/javax.crypto.SealedObject_1234567890","keyFilePath":"/home/bitbucket/javax.crypto.spec.SecretKeySpec_1234567890"}

コマンドを実行すると、シークレットが復号化されて次のように出力されます。

2023-10-13 05:01:14,203 main INFO [com.atlassian.secrets.DefaultSecretStoreProvider] Initiating secret store class: com.atlassian.secrets.store.algorithm.AlgorithmSecretStore
2023-10-13 05:01:15,991 main DEBUG [secrets.store.algorithm.AlgorithmSecretStore] Initiate AlgorithmCipher
2023-10-13 05:01:16,068 main DEBUG [secrets.store.algorithm.AlgorithmSecretStore] Decrypting data...
2023-10-13 05:01:16,250 main DEBUG [secrets.store.algorithm.AlgorithmSecretStore] Decryption done.
Success! Decrypted password using cipher provider: com.atlassian.secrets.store.algorithm.AlgorithmSecretStore decrypted password: secret

Recreate encrypted data

If you lose an encrypted password and try to encrypt the plaintext password once again, the new encrypted password will look different. This is not an issue, as it will still represent the same plaintext password. However, in some cases, you might want to keep it consistent, for example by having the same encrypted password when a Bitbucket instance is migrated to another server.

以前とまったく同じ方法でパスワードを暗号化するには、元のパスワードの暗号化に使用したキーとアルゴリズム パラメータが必要です。いずれもも暗号化ツールによって生成され、以下のファイルに保存されています。

• Key: javax.crypto.spec.SecretKeySpec_[timestamp]
• Algorithm parameters: java.security.AlgorithmParameters_[timestamp]

これらのファイルを見つけたら、JSON オブジェクトにある 2 つの追加フィールドによって暗号化ツールにその場所を指し示せます。 

{"plainTextPassword":"secret","algorithm":"AES/CBC/PKCS5PADDING","algorithmKey":"AES","algorithmParametersFilePath":"/home/bitbucket/java.security.AlgorithmParameters_1234567890","keyFilePath":"/home/bitbucket/javax.crypto.spec.SecretKeySpec_1234567890"}

To encrypt the password, follow the steps in the first step, Encrypt the password, and use the JSON object with the key and algorithm parameters.
