EnigMachine
Secrets are everywhere, in a world that is becoming more and more open how do you protect them?
During World War II, it took a considerable team of cryptologists to crack messages intercepted from the Germans.
With EnigMachine, you too can hide secret messages that only you, or anyone you give the key to, can easily decipher.
Send secret messages to other people or write notes to yourself that, only with the correct unique key,
only you can decrypt.
Features:
> 5 unique types of ciphers each with their different key types!
> Random encryption, a cipher type practically impossible to decrypt but can throw people off if you think they're trying to read your messages.
> Simply decrypt any received message you have the key to!
(Free (but more limited) version of EnigMachine also available here).
