「Cryptalk(クリプトーク)」は、あなたの秘密のメッセージを、意味不明な文字列ではなく「ごく自然な文章」に変換する新しい暗号化アプリです。 通常の暗号文のように目立つことなく、SNSの投稿やメッセージアプリでの会話に違和感なく溶け込みます。大切な人との秘密のやり取りや、自分だけの秘密のメモに最適です! 【Cryptalkの主な機能】 自然文への暗号化: 入力した秘密のテキストを、一見すると普通の文章(自然文)に変換します。 簡単・スムーズな復号: 送られてきた自然文をアプリに入力するだけで、すぐに元のテキストを復元できます。 履歴の保管庫機能: 過去に暗号化した文章や、復元したメッセージは自動でローカル保存。タブで簡単に切り替えて後から見返すことができます。 ワンタップコピー: 出力された暗号文や自然文はボタン一つでコピー可能。すぐに他のアプリで共有できます。 ダークテーマ対応: 洗練されたダークUIで、目に優しくスタイリッシュに操作できます。 【PRO版(買い切り)でさらに強力に!】 無料版でも基本機能はしっかりお使いいただけますが、PRO版にアップグレードすると以下の高度な機能が解放されます。 完全広告非表示: 画面下部のバナー広告や、復号時の動画広告が一切表示されなくなり、ストレスフリーに。 暗号キー(パスワード)機能: 暗号化時にあなただけの「キー」を設定可能。同じキーを知っている相手しか復号できなくなるため、セキュリティが大幅に向上します。 4つの自然文スタイル選択: 自然さ優先: 会話に溶け込みやすく、違和感を抑えた文体 識別性優先: 単語の区別がしやすく、見返したときに判別しやすい文体 自然文短め: 全体の文字数を抑え、スッキリとまとまりやすい文体 連結文: 文同士をつなげて流れを作り、ひと続きの文章に見せる文体 暗号の長さ指定: 用途に合わせて「通常」と「短縮」から長さを選択可能。 【こんな時に便利!】 第三者に見られたくないパスワードや個人情報をメモしておく時 友人や恋人と、タイムライン上で秘密の会話を楽しみたい時 普通の会話に見せかけて、特定の相手にだけ真意を伝えたい時 【注意事項】 入力可能な文字はアプリ内部のデータに依存します。未対応の文字は使用できません。 PRO版で「暗号キー」を設定した場合、キーを忘れると元の文章を復元できなくなりますのでご注意ください。
