ハッシュ化されたメールアドレスまたは電話番号を使用する
この API は、SHA256 でハッシュ化されたメールアドレスと電話番号を受け入れます。SDK を呼び出す前にコードでハッシュ化を行うことで、ユーザーのデータを管理できます。
ハッシュ化された認証情報を使用するには、住所と番号を正規化し、SHA256 でハッシュ化してから API を呼び出します。
メールアドレスと電話番号を正規化する
メールアドレスの場合、Google Analytics API は SHA256 が適用される前に特定の正規化が実行されることを前提としています。そのため、次の手順に沿ってデータを正規化してください。

If a match is found with either API, then subsequent API call are effectively ignored. \n\n```swift\nimport FirebaseAnalytics\n\n// ...\n// If you're using an email address....\nAnalytics.initiateOnDeviceConversionMeasurement(emailAddress: \"example@gmail.com\")\n// If you're using a phone number....\nAnalytics.initiateOnDeviceConversionMeasurement(phoneNumber: \"+15555555555\")\n```\n\nObjective-C\n\nImport the `FirebaseAnalytics` module and pass in the email address to the\n`initiateOnDeviceConversionMeasurementWithEmailAddress:` API or the phone\nnumber to the `initiateOnDeviceConversionMeasurementWithPhoneNumber:` API.\n**Note:** The `initiateOnDeviceConversionMeasurementWithEmailAddress:` and `initiateOnDeviceConversionMeasurementWithPhoneNumber:` methods may be called sequentially, but only one match can be reported per user.

You\ncan maintain control of your user's data by performing the hashing in your code\nbefore making calls to the SDK.\n\nTo use hashed credentials, normalize addresses and numbers, hash them with\nSHA256, then call the API.\n\nNormalize email addresses and phone numbers\n\nFor **email addresses** , the Google Analytics API assumes that a\nparticular normalization is performed before SHA256 is applied, so follow these\nsteps to normalize your data:\n\n1. Convert the entire email address to lowercase.\n\n2. If the email address ends in domain *@googlemail.com* , replace the\n *@googlemail.com* domain with *@gmail.com*.\n\n3. For addresses ending in domain *@gmail.com* (including those modified in\n the previous step):\n\n 1. Remove all periods from the username portion.\n\n 2. Make the following substitutions in the username portion:\n\n - For letters I or i, or digit 1, substitute letter l\n - For digit 0, substitute letter o\n - For digit 2, substitute letter z\n - For digit 5, substitute letter s\n\nFor example, after normalization:\n\n- `an.email.user0125@googlemail.com` becomes `anemalluserolzs@gmail.com`\n- `CAPSUSER0125@provider.net` becomes `capsuser0125@provider.net`\n\nFor **phone numbers**, numbers must already be in E.164 format (that is,\nprefix with +, 1-3 digits for country code, max 12 digits for subscriber number)\nprior to hashing with SHA256.\n\nNote that the hashed SHA256 email or phone numbers must be 32 bytes long\nand not a hexadecimal string.\n\nCall the API with hashed credentials \n\nSwift\n\nImport the `FirebaseAnalytics` module and pass in the email address or phone\nnumber to the `initiateOnDeviceConversionMeasurement()` API.\n**Note:** The `initiateOnDeviceConversionMeasurement(hashedEmailAddress:)` and `initiateOnDeviceConversionMeasurement(hashedPhoneNumber:)` methods may be called sequentially, but only one match can be reported per user.
