About this tool:
- This tool allows you to encrypt the entered text and decrypt the data. You can also "copy", "download", and "save offline" the data.
- The encrypted string can be displayed as the original text using the "Decrypt" button.
- The "AES (Advanced Encryption Standard) encryption method" used here provides a simple yet powerful security function that allows you to encrypt and decrypt the input text using a password. AES is a highly advanced encryption technology that is also used by government agencies and companies and is widely adopted for protecting important data.
About offline saving:
This tool provides a feature for saving and managing data offline. This allows you to handle data securely within your device without sending it to a server.
- Local storage of encrypted data
- The generated encrypted data is saved in the browser's local storage. This allows the data to be safely stored on your device without being transmitted over the internet. By saving the data to local storage, it is retained persistently beyond the browser session.
When saving new data, the previously saved data will be overwritten. If you want to keep the previous data, it is recommended to back it up by downloading it.
- Restoring encrypted data
- The saved encrypted data can be easily loaded from local storage and restored to the input field in the tool. This process is entirely local and does not involve any communication with external servers.
- Deleting data from local storage
- The saved data can be deleted from local storage when necessary. The deleted data is completely erased and cannot be accessed again. This process is also local, ensuring secure data management.
Important notes:
- 1. The importance of passwords
- This tool uses the password specified by the user for encryption and decryption. Make sure to write down the password and not forget it. Without the specified password, it is impossible to decrypt the encrypted data.
- 2. How to share passwords
- When exchanging encrypted data with a third party, you must inform them of the password used during encryption. Share the password using a reliable method, and avoid sending it via insecure means such as email.
- 3. Regarding security
- While data encrypted using this tool is protected, it could be deciphered if a malicious person obtains the data and the password or encryption algorithm has weaknesses. Be cautious when sending important data, and ensure appropriate security measures are taken.
Recommendations for serious use:
- For more robust encryption, it is recommended to use a randomly generated key and initialization vector (IV). This improves security and better protects the data. Random keys and IVs can be generated using specialized tools or libraries.
Handling important data:
- Avoid uploading encrypted data to web servers that can be accessed by an unspecified number of people.
- Do not send encrypted data and the password together via email or carry them together, as this increases the risk of unauthorized access.
Privacy:
- The text and encrypted data entered into this tool are not sent to the server; all processing is done within the user's browser.
