How to write an invisible message in WhatsApp - briefly?

To create an invisible message on WhatsApp, you can use the "Text Status" feature. Simply type your message in white font color against a white background, making it unreadable until revealed with a black light or dark mode.

How to write an invisible message in WhatsApp - in detail?

Writing an invisible message in WhatsApp can be a useful skill for maintaining privacy or leaving subtle hints. This process involves using various techniques to hide the content of your message within visible text. Here are some detailed methods to achieve this:

Using Unicode Characters

Unicode characters provide a vast array of symbols and letters that can be used to create hidden messages. By strategically placing these characters in your text, you can form an invisible message that only those familiar with the technique will understand.

1. Selecting Unicode Characters: Choose Unicode characters that are visually similar to regular alphabet characters but have different meanings or no visible representation. For example, you might use characters like "⸮" (U+2E2C) which looks like a space, or "‍" (U+200D) which is a zero-width joiner.
2. Forming the Message: Arrange these Unicode characters in a sequence that spells out your hidden message. For instance, if you want to write "secret", you might use a combination of visually similar but distinct Unicode characters.
3. Sending the Message: Integrate these Unicode characters into your regular text. The recipient will see normal-looking text, but those who know the technique can extract the hidden message by identifying and translating the Unicode characters.

Using Whitespace Characters

Whitespace characters are another effective way to create invisible messages. These characters do not display visibly on most platforms but still transmit data.

1. Selecting Whitespace Characters: Common whitespace characters include " " (U+0020), "‍" (U+200B), and "‍" (U+FEFF).
2. Forming the Message: Arrange these whitespace characters to spell out your hidden message. For example, you can use a sequence of spaces and zero-width spaces to form a phrase.
3. Sending the Message: Integrate these whitespace characters into your text. The recipient will see no visible change, but those who know how to view non-printing characters can extract and read the hidden message.

Using Encryption Techniques

For more advanced users, encryption techniques can be employed to create invisible messages. This method requires some technical knowledge and tools.

1. Choosing an Encryption Method: Select a simple encryption algorithm like Caesar cipher or use online tools that offer encryption services.
2. Encoding the Message: Convert your message into encrypted text using the chosen algorithm or tool.
3. Sending the Message: Integrate the encrypted text into your regular conversation. The recipient will see gibberish, but those with the decryption key can read the hidden message.

Using Image-Based Techniques

Images can also be used to hide messages within WhatsApp. This method involves embedding data within an image file.

1. Selecting an Image: Choose an innocuous image that will not arouse suspicion.
2. Embedding the Message: Use software like Stegano or online tools to embed your message into the image's metadata.
3. Sending the Message: Share the image with the recipient. They can use similar software or tools to extract and read the hidden message from the image's metadata.

Conclusion

Writing invisible messages in WhatsApp requires a combination of creativity and technical knowledge. Whether you choose Unicode characters, whitespace characters, encryption techniques, or image-based methods, the key is to ensure that your recipient understands how to decode the hidden message. Always remember to use these techniques responsibly and ethically.
