-Extract two-factor authentication (2FA, TFA) secret keys from export QR codes of "Google Authenticator" app.
-The secret and otp values can be printed and exported to json or csv. The QR codes can be printed or saved as PNG images.
+The Python script `extract_otp_secrets.py` extracts one time password (OTP) secrets from QR codes exported by two-factor authentication (2FA) apps such as "Google Authenticator".
+The exported QR codes from authentication apps can be read in three ways:
+
+1. Capture from the system camera using a GUI, _(new!)_
+2. Read image files containing the QR codes, and _(new!)_
+3. Read text files containing the QR code data generated by third-party QR readers.
+
+The secret and otp values can be exported to json or csv files, as well as printed or saved to PNG images.
+
+**The project and the script were renamed from extract_otp_secret_keys to extract_otp_secrets in version 2.0.0.**
+
+## Installation
+
+```
+git clone https://github.com/scito/extract_otp_secrets.git
+cd extract_otp_secrets
+pip install -U -r requirements.txt
+
+python src/extract_otp_secrets.py example_export.txt
+```
+
+In case this script is not starting properly, the debug mode can be activated by adding parameter `-d` in the command line.
+
+### Installation of shared system libraries
+
+For reading QR codes with `ZBAR` QR reader, the zbar library must be installed.
+If you do not use the `ZBAR` QR reader, you do not need to install the zbar shared library. Note: The `ZBAR` QR reader is the showed for me the best results and is thus default QR Reader.
+
+For a detailed installation documentation of [pyzbar](https://github.com/NaturalHistoryMuseum/pyzbar#installation).
+
+#### Linux (Debian, Ubuntu, ...)
+
+    sudo apt-get install libzbar0
+
+#### Linux (OpenSUSE)
+
+    sudo zypper install libzbar0
+
+#### Linux (Fedora)
+
+    sudo dnf install libzbar0
+
+#### Mac OS X
+
+    brew install zbar
+
+#### Windows
+
+##### zbar
+
+The zbar DLLs are included with the Windows Python wheels. However, you might need additionally to install [Visual C++ Redistributable Packages for Visual Studio 2013](https://www.microsoft.com/en-US/download/details.aspx?id=40784). Install `vcredist_x64.exe` if using 64-bit Python, `vcredist_x86.exe` if using 32-bit Python. For more information see [pyzbar](https://github.com/NaturalHistoryMuseum/pyzbar)
+
+##### OpenCV
+
+OpenCV requires [Visual C++ redistributable 2015](https://www.microsoft.com/en-us/download/details.aspx?id=48145). For more information see [opencv-python](https://pypi.org/project/opencv-python/)
 
 ## Usage
 
-1. Export the QR codes from "Google Authenticator" app
-2. Read QR codes with QR code reader
-3. Save the captured QR codes in a text file. Save each QR code on a new line. (The captured QR codes look like `otpauth-migration://offline?data=...`)
-4. Call this script with the file as input:
+### Capture QR codes from camera (since version 2.0.0)
 
-        python extract_otp_secret_keys.py -p example_export.txt
+1. Open "Google Authenticator" app on the mobile phone
+2. Export the QR codes from "Google Authenticator" app
+3. Point the QR codes to the camera of your computer
+4. Call this script without infile parameters:
 
-## Dependencies
+    python src/extract_otp_secrets.py
 
-    pip install -r requirements.txt
+![CV2 Capture from camera screenshot](cv2_capture_screenshot.png)
 
-Known to work with
+### With builtin QR decoder from image files (since version 2.0.0)
 
-* Python 3.10.6, protobuf 4.21.5, qrcode 7.3.1, and pillow 9.2
+1. Open "Google Authenticator" app on the mobile phone
+2. Export the QR codes from "Google Authenticator" app
+4. Save the QR code as image file, e.g. example_export.png
+5. Transfer the images files to the computer where his script is installed.
+6. Call this script with the file as input:
 
-For protobuf versions 3.14.0 or similar or Python 3.6, use the extract_otp_secret_keys version 1.4.0.
+    python src/extract_otp_secrets.py example_export.png
 
-### Optional
+### With external QR decoder app from text files
 
-For printing QR codes, the qrcode module is required, otherwise it can be omitted.
+1. Open "Google Authenticator" app on the mobile phone
+2. Export the QR codes from "Google Authenticator" app
+3. Read QR codes with a QR code reader (e.g. from another phone)
+4. Save the captured QR codes in the QR code reader to a text file, e.g. example_export.txt. Save each QR code on a new line. (The captured QR codes look like `otpauth-migration://offline?data=...`)
+5. Transfer the file to the computer where his script is installed.
+6. Call this script with the file as input:
 
-    pip install qrcode[pil]
+    python src/extract_otp_secrets.py example_export.txt

+## KeePass
+
+[KeePass 2.51](https://keepass.info/news/n220506_2.51.html) (released in May 2022) and newer [support the generation of OTPs (TOTP and HOTP)](https://keepass.info/help/base/placeholders.html#otp).
+
+KeePass can generate the second factor password (2FA) if the OTP secret is stored in `TimeOtp-Secret-Base32` string field for TOTP or `HmacOtp-Secret-Base32` string field for HOTP. You view or edit them in entry dialog on the 'Advanced' tab page.
+
+KeePass provides menu commands in the main window for generating one-time passwords ('Copy HMAC-Based OTP', 'Show HMAC-Based OTP', 'Copy Time-Based OTP', 'Show Time-Based OTP'). Furthermore, one-time passwords can be generated during auto-type using the {HMACOTP} and {TIMEOTP} placeholders.
+
+In order to simplify the usage of the second factor password generation in KeePass a specific KeePass CSV export is available with option `-keepass` or `-k`. This KeePass CSV file can be imported by the ["Generic CSV Importer" of KeePass](https://keepass.info/help/kb/imp_csv.html).
+
+If TOTP and HOTP entries have to be exported, then two files with an intermediate suffix .totp or .hotp will be added to the KeePass export filename.
+
+Example:
+- Only TOTP entries to export and parameter --keepass example_keepass_output.csv<br>
+    → example_keepass_output.csv with TOTP entries will be exported
+- Only HOTP entries to export and parameter --keepass example_keepass_output.csv<br>
+    → example_keepass_output.csv with HOTP entries will be exported
+- If both TOTP and HOTP entries to export and parameter --keepass example_keepass_output.csv<br>
+    → example_keepass_output.totp.csv with TOTP entries will be exported<br>
+    → example_keepass_output.hotp.csv with HOTP entries will be exported
+
+Import CSV with TOTP entries in KeePass as
+
+- Title
+- User Name
+- String (TimeOtp-Secret-Base32)
+- Group (/)
+
+Import CSV with HOTP entries in KeePass as
+
+- Title
+- User Name
+- String (HmacOtp-Secret-Base32)
+- String (HmacOtp-Counter)
+- Group (/)
+
+KeePass can be used as a backup for one time passwords (second factor) from the mobile phone.

-# Extract two-factor authentication (2FA, TFA) secret keys from export QR codes of "Google Authenticator" app
-#
-# Usage:
-# 1. Export the QR codes from "Google Authenticator" app
-# 2. Read QR codes with QR code reader (e.g. with a second device)
-# 3. Save the captured QR codes in a text file. Save each QR code on a new line. (The captured QR codes look like "otpauth-migration://offline?data=...")
-# 4. Call this script with the file as input:
-#    python extract_otp_secret_keys.py -p example_export.txt
-#
-# Requirement:
-# The protobuf package of Google for proto3 is required for running this script.
-# pip install protobuf
-#
-# Optional:
-# For printing QR codes, the qrcode module is required
-# pip install qrcode
-#
-# Technical background:
-# The export QR code of "Google Authenticator" contains the URL "otpauth-migration://offline?data=...".
-# The data parameter is a base64 encoded proto3 message (Google Protocol Buffers).
-#
-# Command for regeneration of Python code from proto3 message definition file (only necessary in case of changes of the proto3 message definition):
-# protoc --python_out=generated_python google_auth.proto
-#
-# References:
-# Proto3 documentation: https://developers.google.com/protocol-buffers/docs/pythontutorial
