About mobilEEnigma 2nd generation :

mobilEEnigma II has a new version with a new cipher design formula. That new version can decipher your old text by preceding your cipher text with two uppercase ‘E’, like EE , then it will decipher 1st generation ciphered text.

Any contacts ciphered with mobilEEnigma 1st version will be request by this version to be converted to new version. To convert using 2nd generation formula, enter the password or passphrase that has been used to cipher then, then list them by touching he [contact] button. By selecting a contact already cipher for review, mobillEEnigma will ask to convert them, simply touch [YES], then it will be cipher with second generation formula.

Why a second generation?
The first generation has been design to cipher ASCII text only like english or french language, so this was not working for foreign language like asiatic or arabic language. The second generation is using unichar instead of byte.

Ratings and Reviews

Could be a 5 star App but essential feature is missed


Great app to cipher/decipher text. However it lacks the feature to save a ciphered text document to be later opened and deciphered in the app. The ciphered text can be copied but not saved. If you could save/open or manage ciphered document texts it'd generated by the app it'd be great.
