Description

OVERVIEW:

A simple, minimalistic, user friendly app, that allows youtoencrypt text¹ using a secret key² into a ciphertext and thensendit via SMS, social apps or simply copy and paste it whereveryouwant. This app uses AES (Advanced Encryption Standard) toencrypttext, so far the only working way of breaking AES withoutknowingthe secret key is by brute force which can take up to a fewbillionyears for a good password.

If you want to read an encrypted text message you shouldfirstknow the secret key and the key length(128, 192 or 256),withoutknowing them you can't decrypt the ciphertext and readit.
-------------------------------------------------------------------------------------------------------------------------------------

USAGE:

The usage of this app is pretty straightforward, howevertwothings are worth mentioning:

1. CHANGING THE KEY LENGTH is done by pressing the"AES-###"button at the top of the app, where ### is the bit lengthof thesecret key, it can be set to 128, 192 or 256. Different keysizesencrypt text differently even with the same key.

2. PASTING TEXT³ can be done simply by long pressing thetextfield.

*You can encrypt text with this app multiple timesusingdifferent secret key and key size.
-------------------------------------------------------------------------------------------------------------------------------------

DISCLAIMER:

1. The developer of this app distances himself from thecontentsof the encrypted messages made by its users. Using anykindencryption for criminal activity is illegal. AES(AdvancedEncryption Standard) also known as Rijndael developed bytheBelgian cryptographers Joan Daemen and Vincent Rijmen is themostwidely used symmetric-key encryption algorithm today andisavailable for free use in many apps.

2. In case of a published practical cryptographic "break"fasterthan a brute force against AES, the developer of this appmustchange the encryption algorythm within a week, howeverthedeveloper will not be responsible for any previousencryptedmessages that can be broken.

3. The developer of this app is not responsible if aciphertextis somehow decrypted using the secret key (or the samebitstream)by an unwanted third party, the secret key can beuncovered inmultiple ways for example using a malicious software(keylogger) orbeing leaked by one of the original users. So far thefastestmethod of breaking an AES ciphertext, having only theciphertext,is a brute force attack, so using strong passwords ishighlyrecommended.
-------------------------------------------------------------------------------------------------------------------------------------

NOTE_1: The text can be written in any language and inanyalphabet that is widely used today, all Unicode/UTF-8characterscan be used.

NOTE_2: The key also accepts all Unicode/UTF-8 characters,thestrength of the secret key is determined by its length andthevariety of different characters that are being used.

NOTE_3: Pasting the ciphertext into the text field istherecommended way of inputting a ciphertext. Simply copy thetextmessage from the SMS or any other app.

NOTE_4: Encrypt text with this app and enjoy safecommunicationwith you friends and colleagues.
