Description

Kryptomat - The Cryptography App

With the app Kryptomat any texts can be encrypted. For encryption Kryptomat uses here the RSA algorithm. RSA (Rivest, Shamir, Adleman) is an asymmetric cryptographic method that can be used for both encryption and digital signature. In the asymmetric process, two key pairs are used, in contrast to a symmetric cryptosystem. A public key pair to encrypt data and a secret key pair to decrypt data. Data can be encrypted with the public key pair, which again only the owner of the secret key can decrypt. The communicating parties need therefore not to know a shared secret key, which contributes to increased security of the encryption.
With Kryptomat texts of any length can be encrypted using the RSA method. The strength of the encryption can here be specified during encryption using the bitlength (military standard are 1024 bits) of the primes to be generated. The bitlength is, however, dependent on the available heap memory in Android. Due to this restriction key pairs could be produced with a maximum bitlength of 1023 with the devices tested so far.

Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why ApkClean.net can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.

User's Reivew

1 ★The private key file is not encrypted by an AES passphrase. Any app that can read storage can read the private key file and decrypt any stored ciphertext. It totally defeats the purpose of encryption if the user does not keep a secret off the device.
3 ★It's cool for challenges and learning about rsa and/or asymmetric cryptography. But if you really need public key cryptography for serious purposes look no further than openkeychain.
