Welcome to our free online tool that allows you to encrypt and decrypt your text using the AES encryption method. Whether you're securing your personal notes or sharing sensitive information, our tool provides a quick and secure way to handle your text encryption needs.
How to Use the Tool
To encrypt your text, simply enter it into the input box below, provide an optional custom key, and click 'Encrypt'. To decrypt, paste your encrypted text, enter the same key you used for encryption, and click 'Decrypt'. It's that simple!
Advice on Creating a Secret Key Between Two People
1. Key Length and Complexity
Use Sufficient Length: A longer key generally offers more security. For many encryption algorithms like AES, a key length of 256 bits (32 characters in hexadecimal) is recommended.
Incorporate Complexity: Use a mix of uppercase and lowercase letters, numbers, and symbols. Avoid predictable patterns like "1234" or "password".
2. Memorable Yet Secure
Passphrase Approach: Create a passphrase based on a unique sentence or song lyric known only to the two of you. Choose a line that is not widely known or published.
Acronyms and Mnemonics: Convert a memorable phrase into an acronym, possibly interspersed with numbers or symbols for added security.
3. Randomness
Use a Random Generator: Ideally, generate a key using a cryptographic random number generator. This ensures the key is not easily guessable.
Avoid Common Words: Do not base the key on dictionary words or easily associated items like birthdays or names.
4. Secure Communication Channel
In-Person Communication: If possible, meet in person to exchange the key, where eavesdropping is less likely.
Encrypted Messaging: If physical meetings aren't possible, use encrypted communication channels to share the key. Applications like Signal or end-to-end encrypted email can be useful.
5. Consistent Changes and Updates
Regular Changes: Agree to change the key regularly (e.g., monthly or quarterly) to mitigate the risk of exposure.
Plan for Contingencies: Decide in advance how to securely communicate a new key if privacy is compromised.
6. Key Storage
Secure Physical Storage: If the key must be written down, store it in a secure location like a locked safe or a secure password manager.
Avoid Digital Copies: Minimize the risk of digital interception by avoiding text files or unsanctioned apps that might be insecure.
7. Legal and Ethical Considerations
Ensure Legality: Be aware of the legal implications of key sharing in your jurisdiction, especially in contexts involving sensitive information.
Respect Mutual Agreement: Both parties should agree fully on the methods used for generating and sharing the key to maintain trust and clarity.
