    Emojis of Death
    Emojis of Death is a down and dirty browser app, written in HTML. It's HTML, so it will work on anything a web browser can run on. It's purpose is to hide text strings in emojis, which you can then text or email. An encoded emoji can hold quite a bit of text. The receiver will need Emojis of Death as well, to decode the emoji. The file's small size makes it perfect for your phone. Some email and text services don't work with this, so try it.

    Textcryption

    Textcryption

    Tiny application which allows encrypting basic text.

    Application which allows encrypting text. It is encrypted using own libraries. I think it is a very strong way to encrypt, specially if the text has more than 1 KB. The application reads encrypted bytes from disk, and writes encyrpted bytes to disk, so it never is saved in the hard disk decrypted. JDK-17 compatibility.

    Secure Protocol Format

    Generic binary protocol library that prevents injection attacks

    Injection attacks can occur when transmitted data is not interpreted the same way by both the sender and the receiver. Guaranteeing equivalence in data interpretation, known as operational congruity, is achieved by separating fields of data on the basis of their length. When the length of the data is known, there is no risk of misinterpreting it on the basis of spaces or text delimiters. The Distinguished Encoding Rules, or DER, of the ASN.1 standard follows this approach but includes...
