KryptEY vs Morse
Side-by-side comparison of two open source alternatives
KryptEY
Communicate securely and independent, regardless of the legal situation or whether messengers use E2EE. No server needed. #ChatKontrolleStoppen Why KryptEY? Breaking of end-to-end encryption (E2EE) by laws such as the planned EU chat control is an ongoing issue. Content in messengers that use E2EE, such as Whatsapp or Signal, could thus be monitored by third parties. E2EE is often, but not always, standard in messengers. There are proven methods for E2EE such as PGP. However, these methods are sometimes cumbersomely integrated and require a lot of effort to use. KryptEY is an Android keyboard that implements the Signal protocol. The keyboard works messenger-independently and both the X3DH Key Agreement Protocol and the Double Ratchet Algorithm work without a server, thus it enables a highly independent use of the protocol. Features Based upon Simple Keyboard ( https://github.com/rkkr/simple-keyboard ), KryptEY adds a view above the Keyboard for the E2EE functionality. * use E2EE through Signal Protocol in any messenger * encryption/decryption of messages * enter message through separate text field in keyboard * use clipboard to read messages * manage contacts in own contact list in keyboard * message log to view sent/received messages * send messages as plain JSON (raw mode) or hidden in a decoy text (fairytale mode) * verification of E2EE functionality via fingerprint * Q&A View for questions * dark & light theme See https://github.com/amnesica/KryptEY/blob/master/KRYPTEY.md for further information on how KryptEY is working. Security The existing security properties for the Signal Protocol are also valid for the keyboard. Limitations The keyboard was designed as a POC and only allows 1-to-1 conversations. However, the application can also be used in a group chat to a limited extent. Here, a message can be directed to a specific chat partner and not to all people. Other participants of the group chat cannot decrypt the message. Text messages in Telegram are getting copied as HTML and not as plain text. When decoding the message with the fairytale mode the copied message is compromised and can't be read properly. Therefore, it can't be decoded at all. However, the raw mode works properly. When using KryptEY with Telegram we recommend the raw mode. Some messengers like Threema only allows up to 3500 bytes per message. Therefore, different character input limitations apply. To stay under the 3500 bytes limit, only 500 characters are allowed for raw and fairytale mode. For convenience these limitation applies for all messengers. Demo For a demonstration on how KryptEY is used see https://github.com/amnesica/KryptEY/tree/master#demo KryptEY was created by mellitopia and amnesica.

Morse
Decipher Morse code to text or text to Morse code Turn any text into Morse code, or translate Morse code to text and hear the results. • Clean, modern app design and interface. • Made to be simple to use for everyone. • Realtime translation: type in the word or code and have it translated immediately. • Decode from Morse to text, or text to Morse. • Press the speaker button to hear the code. • Copy the text by pressing the "Copy" button. • Type in dot and dash using our built-in Morse keyboard. • Libre software (https://github.com/Crazy-Marvin/Morse) + More features planned. Don’t let the special characters or dots and dashes befuddle you. Morse code is a system to encode letters and numbers to dash and dot signs. The duration of the dash is three times the duration of a dot. Each dot or dash is followed by period of signal absence, called a space, equal to the dot duration. Morse code was first used for communicating via telegraph. The most well-known Morse code is SOS, which is used to signal an emergency. Aside from typing dots and dashed, you can also signal Morse code by turning light on and off, sounding a horn or tapping, etc. All means of transmitting Mores code require the recipient understands it. If not, our app may be used to find out the message, password, secret number, or any info you want to relay. Nowadays, even though the use of the telegraph has been widely superseded by other communication technologies, Morse code still finds its place in the lives of various individuals. Due to its presence in popular culture, Morse code has been featured in movies, games, and other medias as a simple way to encode messages, inspiring fans to research and explore the language as part of fun, puzzle-solving activities. This makes it useful even in cryptography or cryptogram events as a handy encoding tool. 1. Tell others when you are in a dangerous situation (SOS). 2. Hide your secret number or password via dots and dashes. 3. Cipher or decipher hidden clues in games. 4. Learn cryptography or cryptogram through learning Morse codes. 5. Become a codebreaker by breaking secret codes in real time translation. 6. Create a secret number. + Many more --- It really helps to leave a review or to star the project in the source code repsitory, and it means the world to us. If you have problems using the app, please write an e-mail or open an issue on GitHub. Responses are most often immediate, and bugs are fixed as soon as possible.
