Cryptography

Overall, a very good and well detailed app. My only problem is that once I leave a particular cipher to pick another from the main list, an add comes up that has no "x" to get rid of/skip it. It's written in either Chinese or Japanese and it's very frustrating as I have to close the app and reopen it every time I wish to change cipher. Once that's fixed, a well deserved 5 stars are in order. 🙌

SHOULD COME PRE-INSTALLED ON EVERY PHONE!!! I absolutely love this app. It has taught me so much over the years. I've tried all of the educational and functional cryptography apps on the Store but this guy's is by far the best. *Check out the secure messaging app from Nitramite. It's not practical for everyday use because end-to-end encryption type apps need to be installed on both sending and receiving devices to work but that one is particularly fun for you and your special friends.

An absolutely incredible application, that I have been using for quite a while now. When I first downloaded it, I was greatly surprised by the amount of detail and indeed amount of ciphers/tools available. If I could request one thing, it would be that you add the other variants of the Enigma machine (unless I've just missed them, haha), but I would particularly love to see the M4 machine and perhaps even the K Variant for Railway. Thank you very much for an excellent application!

Right away I can tell this app is very helpful. There are a lot of resources here that were used in my Cryptology college course and anyone that wants to dive deeper into learning cryptography can always research any questions online and fill in the gap! Seriously, many thanks goes out to the developers that put their time and effort into this app. Keep it up y'all! 🎖💎🎯

Absolutely amazing, it let's you know what the cipher does, when it was used, etc. And even lets you play with it so you can experience what the ciphers do and how they work. It also lets you use tools and gives you different information on things like sign language, Braille, etc. 10/10 recommend to anyone interested in cryptography and other things like it.

I love this app so much. I've met it several years ago as kid and enjoyed reading about and trying encoding, hashing and encryption. Back then i didn't understand much, but it sparked my interest. Today i stumbled upon this app on my phone and pleasant nostalgia filled me. Thank you for the work you do.

# Miss the steganography for audio or video files, and the possibility to hide images. # Miss the option to crop image on the fly before encryption for applications like Whatsapp who compress images. EDIT2: Fair enought. Note that it was just an enhancement suggestion. Thanks for your nice application +1 EDIT3: Doesn't support UTF-8 and pwd, doesn't behave correctly in landscape mode and seem to freeze under Android 7.0 on Xiaomi Redmi Note 4 while trying to encode a short message "Processing...

Good for general educational purposes and simple ciphers. That's about where it ends... Many options just feature the same cipher just labeled differently. The Caesar cypher function used with the One-Time Pad section is totally incorrect.

Love this app! I've been interested in both encryption and decryption for quite some time, and not only have I found imensley more ways to do the former, but that the Latter is so much more accomplishable than I had first thought it to be. Well worth your time if you enjoy cryptography.

Had this app for a long time and just rediscovered it. After having to kill the app twice because of an ad that wouldn't go away, I decided to tell you that the app apparently became unusable due to ads since I last used and enjoyed it years ago. Goodbye

The app is super helpful. But I read slot of Gravity Falls fanfiction and most authors use random ciphers in their stories and was disappointed that this app didn't have the a1z26 cipher on it. Maybe that can be something you can add in a later update.

I look for a reliable trustworthy encryption utility by checking number of downloads and the average rating. Guess I need a better method. I want something like a nice user interface in front of openssl or gpg2. In particular, I want to be able to calculate sha1 and sha256 of a 40gb file, encrypt it with aes256 (with advice about cbc vs ecb vs etc) or a public key system, and upload it to Google drive, without having to store it locally. This doesn't call aes by name and can't encrypt files.

Just wonderful! Well worth the money for sure, so many tools and easy to use with its simple design. So glad to have stumbled upon this app. Love how extensive and informational this is and even reading about the app and its description, you really get a feel about how passionate and excited the developer is to share with everyone.

Great cryptography tool and educational app to learn about the different methods of cryptography in history and that are used today. Some tools are still in development or experimental and implementation could be improved, but overall a good app. Please continue development.

Hey ! This is a great app. Wonderful and elite. That's why I am giving it a 5. But, as a concerned user, I have a doubt ! Does this app do any data leak or store our encrypted messages and files and transmit to some remote server in the background.

A lot of work has gone into that app, but also a lot of passion. One of my favourite apps ever, you learn, you play in a very intuitive fashion.

Just by looking at the apps contents it has some potential, in fact a lot of potential to be honest though some aesthetic application could make it better. It could be the best cryptographic app in the store to date.

Really loved it fella. Its a masterpiece. It helps me to learn a lot. This just got me interested much more than I already was in cyber security. From actual tools to demonstrations to facinating stories. Salute to you.

Excellent lineage of cryptographic implementations most often arranged chronologically. Love it for making QR codes and checking the decrypted hyperlinks of random, or untrustworthy QR codes.

Some I knew somewhat about and some I never came across. May use one or two methods one day. Or could use methods not listed within. But for the time spent gathering and listing them is useful to some. Thanks. Will arrange a little something(donation) for your time and effort 👌

It's so informative and easy to navigate on. I've always been looking for an app like this becauae of how interesting codes and ciphers are to me

I find this app great for playing around with different types of cryptography. It is awesome that this app has features that other apps make you pay for (if it means watching an add here and there, so what?). There is a lot of information here. 👍

Fine collection of cyphers to play with, earlier there were no ads though (video in particular)... They're not too frequent at least.

A wonderful application to use. But according to me there must be a guide tour at starting so that we can understand it easily and in a effective way.

Need to rate but first.... This app looks really intetesting. The interface looks fabulous. Looking forward to giving it a whirl.

I recommend this app. You can learn a lot about ciphers and it also help anyone who wanna know how to decode it.

Amazing for screwing around with cryptography or sending stuff to your friends for them to decode. No complaints at all, it is a very good app.

This is a very great app. I've been using it for a while. I'm really impressed on how good this app turned to be. I hope you can add more variants of cryptograms in this app. You can also put some guides on how to use the codes. I'm having big hopes on how far this app can go.
