1 ★ Is this an app, or just an ad interface? I was hoping to do some PGP stuff, but can't seem to do anything but display ads no matter what I tap on.
5 ★ Perfect!!!!! All i wanted was in this app. Thanks!!! Smooth interface And everything perfect!!!
1 ★ Iam not give permission of storage but it can access my storage fix this bugs
5 ★ Best encryption app there is, hands down.
5 ★ One of the top 3 security/encryption apps on the Play Store 100%. Not only do you learn something you can personally become familiar with cryptography and make your own accounts far more secure, as is the intention. The interface took a few moments to become comfortable with. This has become an app I use a lot of the time. Definitely recommend.
3 ★ Bought the pro version, it isn't useful for the encryption of files as it encrypts single files rather than a whole folder but kinda cool for messing with encrytion of basic text.
5 ★ This is one of the first apps I have downloaded with ads that the ads did not affect my opinion of the app. The ads don't disrupt the function of the app.
5 ★ very comprehensive app. enjoying the many mathematical notes and tools. coder has surely a big expertise and passion for encryption.
3 ★ Nice interface, but the main feature I was looking was to encrypt files, and is blocked... ended removing the app after a few minutes. Please consider a trial period at least to allow that test. Also... encryption is just a single file selection, there are many apps offering multiple files encryption in one shot.
5 ★ Excellent, complete set of tools. No idea how to upgrade to PRO, but exceptional piece of software. I cannot talk about the actual encryption quality, I do not know how to verify it. However, assuming the encryption is as good as the interface, it well worth having on your device.
4 ★ Seems like a great tool for encryption purposes. I purchased the pro version thinking it would be more of a teaching tool/information about various encryption types for newbies, however my money is still well spent as I can use this apps tools for encryption generation, decryption, and more.
5 ★ 5 out of 5 Worth every penny! I recommend this to anyone who is looking for a decent app with cryptographic functions and learning. Things I want to see added. 1. Full GPG integration/Multiple keys etc. 2. Ability to encrypt multiple files. 3. Option to save key is not available when you type it in only when random is pressed. 4. Option to create more certificates. Look forward to seeing further updates. Thank you for creating such a useful application.
4 ★ I actually love this program and would give it 5 stars except for the fact it wont let me encrypt anything I want. For instance, Im on a samsung tablet and i want to encrypt folders but there is only an option to encrypt files. Why cant i just create a folder on my system and encrypt the entire contents of the folder? I also wanted to encrypt the whole tablet. Even the lock screen lol I really love encryption, I would recomend this app
5 ★ Just a good learning experience. Just great.
5 ★ Really excellent app to support anyone learning about cryptography and it's a great app to self check/ test progress
