In this method, you’ll use AlgorithmCipher that allows you to choose the algorithm used to encrypt your password in Bitbucket Data Center and Server.

Before you begin: Prepare the JSON object

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

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

ステップ 1. パスワードを暗号化する

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パスワードを暗号化します。

   java -cp "./*" com.atlassian.db.config.password.tools.CipherTool -c com.atlassian.db.config.password.ciphers.algorithm.AlgorithmCipher

   See optional arguments

   • -- silent -s: ログの記録を最小限に制限します。

   • -- help -h: すべてのパラメータを含むヘルプ メッセージを出力します

   • -- mode -m: パスワード処理方法を暗号化または 復号化として定義します。省略した場合は "encrypt" が使用されます

   • -- password -p: 必要な引数を持つ JSON オブジェクトです。省略すると、パスワードの入力を求められます。パスワードがターミナルの履歴に保存されないように、このパラメーターを省略することをお勧めします。

3. After running the command, you'll be asked to provide the required arguments in a JSON object in a single line. Prepare it based on the information from Before you begin.

When encrypting your password, 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

Change the permissions on the files generated by the tool so that they are read-only to the user running Bitbucket. Note that if a multi-node cluster is in use, then the files should be available on the same path for all nodes. Bitbucket needs to be able to access and read those files to decrypt your password and connect to the database.

次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]
  Algorithm parameters used to encrypt your password. You will need this file only if you want to recreate an encrypted password. 

Step 3. (Optional) Store file paths as environment variables

This step is optional. You can store paths to the generated files as environment variables. If the paths aren't present in the bitbucket.properties file and the jdbc.password is an empty JSON object ({}), AlgorithmCipher will look for them in the environment. This way, file paths are not stored in the file, making it difficult to locate the files used for encryption.

1. Store the two generated files as environment variables. You don't need to add the file with algorithm parameters, because AlgorithmCipher does not use it to decrypt the password. You must set the following environment variables to the correct values in any of the scripts used for launching your Bitbucket instance:

   com_atlassian_db_config_password_ciphers_algorithm_javax_crypto_spec_SecretKeySpec
   com_atlassian_db_config_password_ciphers_algorithm_javax_crypto_SealedObject

2. Edit the output from the first step, Encrypt the password, and remove paths to the files. The decrypter class name and password should match the following:

   jdbc.password.decrypter.classname=com.atlassian.db.config.password.ciphers.algorithm.AlgorithmCipher
   jdbc.password={}

Step 4. Add the encrypted password to bitbucket.properties

1. Go to the Bitbucket home directory and back up the bitbucket.properties file. Move the backup to a safe place, ideally outside your instance.

2. In the bitbucket.properties file, replace the jdbc.password property with the output JSON object. Depending on whether you’re using environment variables or not, adjust the JSON object to one of the following examples:

   • If you’re storing file paths as environment variables, remove the paths from the output. The properties should look like the following:

     jdbc.password.decrypter.classname=com.atlassian.db.config.password.ciphers.algorithm.AlgorithmCipher
     jdbc.password={}

   • If you’re not using environment variables and want to stick to file paths in the bitbucket.properties file, make sure you update their paths after moving them to a secure place. The properties should look like the following: 

     jdbc.password.decrypter.classname=com.atlassian.db.config.password.ciphers.algorithm.AlgorithmCipher
     jdbc.password={"sealedObjectFilePath":"/home/bitbucket/javax.crypto.SealedObject_123456789","keyFilePath":"/home/bitbucket/javax.crypto.spec.SecretKeySpec_123456789"}

   • WINDOWS You shouldn’t use backslashes in the path to avoid JSON parsing errors. The paths should look like the following example:

     jdbc.password.decrypter.classname=com.atlassian.db.config.password.ciphers.algorithm.AlgorithmCipher
     jdbc.password={"sealedObjectFilePath":"C:/bitbucket/javax.crypto.SealedObject_123456789","keyFilePath":"C:/bitbucket/javax.crypto.spec.SecretKeySpec_123456789"}

3. Restart Bitbucket.

パスワードを復号化する

To decrypt an encrypted password, extend the command used earlier with the -m decrypt parameter:

java -cp "./*" com.atlassian.db.config.password.tools.CipherTool -c com.atlassian.db.config.password.ciphers.algorithm.AlgorithmCipher -m decrypt

When asked for the password, provide the JSON object from your bitbucket.properties file.

{"sealedObjectFilePath":"/home/bitbucket/javax.crypto.SealedObject_123456789","keyFilePath":"/home/bitbucket/javax.crypto.spec.SecretKeySpec_123456789"}

 {}

暗号化されたパスワードを再作成する

If you lose an encrypted password and try to encrypt the plain text password once again, the new encrypted password will look different. This is not an issue, as it will still represent the same plain text 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":"yourPassword", "algorithm":"AES/CBC/PKCS5PADDING", "algorithmKey":"AES", "algorithmParametersFilePath":"java.security.AlgorithmParameters_123456789", "keyFilePath":"javax.crypto.spec.SecretKeySpec_123456789"}

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.
