There are a few techniques for secret writing that you can add to your skill set:

1. Steganography: This is the practice of hiding a message within an image, audio, or video file. The message can be hidden in the file’s metadata, or it can be embedded in the file in such a way that it is not noticeable to the naked eye.

2. Cipher: A cipher is a method of encrypting a message by replacing each letter with a different letter or symbol. There are many different ciphers that you can use, ranging from simple substitution ciphers to more complex algorithms like AES (Advanced Encryption Standard).

3. One-time pad: A one-time pad is a type of cipher that uses a randomly generated key to encrypt a message. It is considered to be unbreakable as long as the key is kept secret and used only once.

4. Invisible ink: This is a method of writing a message using a substance that is not visible to the naked eye, such as lemon juice or milk. The message can be revealed by heating the paper or applying a chemical agent.

It’s important to note that the use of secret writing techniques can be illegal in some cases, so it’s important to be aware of the laws in your area and use these techniques responsibly.
