Comments on Cryptool for Android

★★★★☆ A Google user · Aug 6, 2018

Great app. Though. We use Android and Windows together more and more though, so it would be really useful if there was a simple compatible Windows app.

★★★★★ Stan The Man · Apr 21, 2026

This is fantastic tool. In this day and age Open Source app is always welcomed. By the way THANK YOU for GitHub SMS version. Keep up the good work 👍

★★★★★ Giuseppe C · May 21, 2018

It's fine. I don't know if it does cypher other than AES with 256bit keys, though.

★★★★★ Technical SharmaJi · May 19, 2020

Best tool ever. Love it... But a little bit slow... Do some work on this app. To correct RC4.

★★★★★ Mr. Hitchens · Jun 28, 2021

Really good tool. Needs an update! Very useful and well-designed. Recommend highly! PS, Instagram User...... seriously, if you don't understand how something works, that's YOUR fault! Read!

Quite useless. No way to really decipher either message with an external source. Only useful for yourself which is kinda sad, as I wanted to use this to make puzzles for other people. Oh well.

★☆☆☆☆ Bob A · Jun 29, 2024

AGAIN, "AES BANK GRADE/MILITARY" IS NSA BACKDOOR. M/AS WELL EAT BUGS W/THESE ALGOS. NOTHING SHOULD BE "REACHED FOR" AT THE TOP OF ANY APP, OTHER THAN COPYING SPECIFIC TEXT. ALL CONTROLS AT BOTTOM & ABOVE KEYBOARD. AMAZED U KNOW WHAT SCREEN PROTECTION IS, A LEGIT SIGN OF HOPE👉✅. ANONYMOUS MESSENGER IS A 🏆 STANDARD GUIDE IN SEVERAL AREAS. COPY/PASTE FROM REAL ENCRYPTION, SECURES CLIPBOARD & LAYERS CURRENT VERIFIED APP ENCRYPTION, ALSO HEDGES AGENT UPDATED DECODES. YOUR MANIFEST IS UNACCEPTABLE.

It is difficult to read the message and the received message cannot be decoded in the program.
