Hi all,

I would appreciate I you can test MicroCrypt for UX design,
usability etc. and let me know. I signed-up with Play Store
for a developer account and they recoment that I should test
my app with at least twelve people, prior releasing.

Here is the download link:

<https://drive.google.com/file/d/1CAD7B5TlNoGeS0DxJlsycH6YO975UWS5/view?usp=drive_link>

Any help and feedback would be very much appreciated!

I am especially interested if the GUI works fine under small
Android devices. Please note: The app is not signed yet and
it may give you a warning, when installing, which you can
ignore.

Regards
Stefan

Why should people do this without any further information?

The link above asks for permission first and I don't even know, what "MicroCrypt" is about and if this is open source or just an attempt to
get malware installed somewhere.

Any help and feedback would be very much appreciated!

You can do the testing in different screen resolutions and Android
versions using the emulator in Android Studio as well.

I tried opening the link on a Galaxy S4 running Android 11 but it wanted me
to sign in to Google Drive, which I wasn't going to do.

(no idea why - the browser was also being funny about opening the link in
the first place and wanted to use the URL as a search term for Google
instead)

The link opened for me instantly in my computer, but it wants me to sign
in, which I will not.

I also would like a description of what this does before trying it.

Same here. The link is probably set up to share only with other Google
users. That's indeed not very nice and AFAIK not needed.

P.S. I first tried it on my laptop where I was already signed-in on my
Google account. Luckily your post warned me to look closely, so I could
bail out before going any further. Then I used another browser where I
was not signed-in on my Google account.

I see. So it this is a kind of cross compiler to create Android packages
based on Go. Well, you can just run the create APK in an emulator which
comes with Android Studio. Did you already try this?

As with Frank, Carlos, Arno & Theo, it asked me to sign into Google Drive.

to continue to Google Drive

I bailed at that point.

Long ago, I posted a dozen sequentially more difficult tutorials for
writing your own code and loading/testing it on your own phone.

I didn't delve into the uploading to Google part though, nor signing.
But it covers every single step of using Android Studio for assembly.

In addition, I wrote up a step-by-step method for assembling source code
off of, oh, I think it was github, using gradle, for, I think, ladb.

If they're useful then we can look them up. If not, no need to bother.
a. A dozen tutorials on using Android Studio to create apps
b. A tested sequence that "compliles" professional source code

Both require Android Studio.

I think we need some good tutorials to rebuild .apk to .aab, because
Google now requires this, as you can no longer upload to Play Store
.apk files. The other thing is sideloading from GitHub etc., which
will be made more difficult by Google this year.

Here you can sideload my signed MicroCrypt, from GitHub:

Since the whole application is only about 759 lines of code it may be
easier to rewrite the code for the app in Kotlin and create a native
Android application with Anroid Studio. All the crypto functions are
available in Kotlin as well and Anroid Studio is available for free for
all major platforms (I used in in Windows 10/11 in the past and now in
Kubuntu Linux 25.10 with KDE 6.5.5 without any problems).

It is now released for internal testing (minimun 12 users and up to 100)
on Play Console. https://play.google.com/apps/internaltest/4699732322065127392

I would appreciate if some of you can test my app and keep it at least for
14 days and please do not opt-out as a tester in that period of time. You probably won't see on your device an app icon. This will be, as understood, happen once the app is officially available.

Arno Welzel wrote:

I wondered what it was myself, so I produce this below for clarification. Anything below can be wrong (and probably is).

MicroCrypt is a small, cross-platform symmetric encryption tool for desktop
and Android. It focuses on simplicity, portability, and modern cryptographic defaults while avoiding unnecessary metadata in encrypted output.

Features
Symmetric file encryption using AES-256-GCM
Password-based key derivation using Argon2id
ISO/IEC 7816-4 padding in 1 KB block multiples
Minimum 12-character password requirement
Simple graphical interface built with the Fyne toolkit
Works on Linux, macOS, Windows, and Android

Cryptography Overview
MicroCrypt uses the following components:

1. AES-256-GCM
Provides authenticated encryption, ensuring both confidentiality and
integrity of the encrypted data.

2. Argon2id
A memory-hard password-based key derivation function designed to resist
brute-force and GPU-based attacks.

3. ISO/IEC 7816-4 Padding
Data is padded to 1 KB boundaries before encryption. This helps reduce
metadata leakage about the original file size.

Installation

Option 1: Install using the Fyne toolchain
go install fyne.io/tools/cmd/fyne@latest
fyne install github.com/Ch1ffr3punk/MicroCrypt/MicroCrypt-Desktop@latest

Option 2: Clone the Git repository
git clone https://github.com/Ch1ffr3punk/MicroCrypt

Use Cases

MicroCrypt is suitable for:
Encrypting personal files with a simple GUI
Cross-platform workflows where the same tool is needed on desktop and
Android
Users who want strong encryption without complex configuration
Situations where avoiding metadata leakage is important

MicroCrypt is not intended for:
Public-key encryption or key exchange workflows
Enterprise or multi-user key management
Automated or scripted encryption pipelines

brute-force and GPU-based attacks.

3. ISO/IEC 7816-4 Padding
Data is padded to 1 KB boundaries before encryption. This helps reduce
metadata leakage about the original file size.

Installation

Option 1: Install using the Fyne toolchain
go install fyne.io/tools/cmd/fyne@latest
fyne install github.com/Ch1ffr3punk/MicroCrypt/MicroCrypt-Desktop@latest

Option 2: Clone the Git repository
git clone https://github.com/Ch1ffr3punk/MicroCrypt

Use Cases

MicroCrypt is suitable for:
Encrypting personal files with a simple GUI
Cross-platform workflows where the same tool is needed on desktop and
Android
Users who want strong encryption without complex configuration
Situations where avoiding metadata leakage is important

MicroCrypt is not intended for:
Public-key encryption or key exchange workflows
Enterprise or multi-user key management
Automated or scripted encryption pipelines

Excellent! I should use this instead of my README, if you agree!

I will later do two small changes to MicroCrypt:

a) Minimum password length of 15 characters, according to the
NIST 800-63B publication https://pages.nist.gov/800-63-3/sp800-63b.html

b) Timeout increase to 5 minutes instead of 1, when the app is idle.

Here's a better readme that may be too much information, but the author
of the app can start with this & reduce it to what he wants to tell us.

It includes the question Arno asked about GPL v3 licensing as a query.

MicroCrypt
A cross-platform symmetric encryption tool for Android and desktop
systems, designed to provide strong cryptographic protection while
minimizing metadata leakage and avoiding unnecessary complexity.

Overview
MicroCrypt encrypts user-supplied text using AES-256-GCM with keys
derived from an Argon2id password-based key derivation function. Prior
to encryption, plaintext is padded according to ISO/IEC 7816-4 rules
and extended to the next 1024-byte boundary. This padding strategy
reduces information leakage about the original plaintext length. All
sensitive data is stored in protected memory using the memguard
library, and is securely destroyed after use.

Cryptographic Design
MicroCrypt uses authenticated encryption with AES-256-GCM. A unique
128-bit salt and 96-bit nonce are generated for each encryption
operation. The salt is used exclusively for Argon2id key derivation,
while the nonce is used by AES-GCM. The final encrypted payload is
encoded as base64 and consists of:
salt || nonce || ciphertext

Key Derivation (Argon2id)
MicroCrypt derives a 256-bit AES key using Argon2id with parameters
chosen to align with OWASP recommendations for interactive password
hashing. The implementation uses the following constants:
- Time cost: 3 iterations
- Memory cost: 64 MiB (64 * 1024 KiB)
- Parallelism: 4 lanes
- Output key length: 32 bytes (256 bits)
These parameters are applied identically during encryption and
decryption. The derived key is zeroed immediately after use.

Padding Scheme
Before encryption, plaintext is padded to the next 1024-byte boundary.
Padding begins with a single 0x80 byte, followed by zero bytes as
needed. This is consistent with ISO/IEC 7816-4 padding semantics and
ensures that the ciphertext length does not reveal the original
plaintext size. During decryption, padding is removed by scanning
backward for the 0x80 marker.

Password Requirements
MicroCrypt currently enforces a minimum password length of 12
characters. The developer has announced an upcoming change to increase
this minimum to 15 characters, following guidance from NIST SP
800-63B. Passwords are handled exclusively in protected memory and are
destroyed immediately after key derivation.

Security Features
- AES-256-GCM authenticated encryption
- Argon2id password-based key derivation
- ISO/IEC 7816-4 padding to 1024-byte boundaries
- memguard-protected memory for all sensitive data
- Automatic clearing of sensitive text after inactivity
- Clipboard auto-clear after 15 seconds
- Rate limiting on decryption attempts
- Secure destruction of keys, buffers, and passphrases

Platform Support
MicroCrypt is implemented in Go and uses the Fyne GUI toolkit.
MicroCrypt runs on:
- Linux
- macOS
- Windows
- Android
The desktop and mobile versions share the same cryptographic logic and
Argon2id parameters.

Installation
Option 1: Install using the Fyne toolchain
go install fyne.io/tools/cmd/fyne@latest
fyne install github.com/Ch1ffr3punk/MicroCrypt/MicroCrypt-Desktop@latest

Option 2: Clone the Git repository
git clone https://github.com/Ch1ffr3punk/MicroCrypt

Usage Notes
MicroCrypt is intended for personal symmetric encryption workflows
where ease of use, portability and strong cryptographic defaults are
desired. It is not designed for public-key encryption, multi-user key
management or automated scripting pipelines. The tool focuses on
minimizing metadata leakage and providing authenticated encryption
without exposing implementation details to the user.

Planned Changes
The developer has announced two upcoming modifications:
- Increase minimum password length to 15 characters
- Increase idle timeout from 1 minute to 5 minutes

I use the fyne toolkit with Go and I have never included such a feature,
so I don't know (yet). But like I said, I like to avoid that, because of
an extra Menu (entry).

thread, or if you have a home page I would add this link. I will
add Arno too.

I'm glad you liked it. I don't need the credits. I don't even know who I am.
I have real peer-reviewed journal articles that give me plenty of credit. >>

Well, I hope you don't mind including you in the README. It is also now
reworked from your source and I like to leave it as it is now. I publish
later the update and then all can review the repository again.

Thanks for your help,which is much appreciated!

Ok, the repository (code and readme) is updated. I will later submit
v0.1.1 to the Play Store. I included you and Arno in the README. :-)

Thanks for helping me out!

Arlen, aka Maria Sophia, is a name shifter. You should know that if you
intend to include his name. Which one?
