Works great and is educational
I got this mostly as an educational resource to learn about encryption but I was surprised to see some of the methods (like the AES one) is actually powerful and very useful! Great app!

What's New in Ares Intel
1.0.1
September 9, 2026
Three fixes to typing and to how results are shown, all reported from real use. Typing in the message field is fixed. Text no longer disappears when you double tap the space bar for a period, and autocorrect now works, including under the two passphrase methods. Decrypted text is easier to read. It no longer breaks words in the middle of a line, and it is set in the reading font rather than the one used for ciphertext. Passphrase entry has moved to its own screen, which is what stops iOS mistaking the message field for a login form.
