Cryptocam allows you to take encrypted photos and videos so your data is safe even if an attacker gains physical access to your device or SD card. Find a full tutorial on https://cryptocam.gitlab.io Worried that your device or memory card might get into the wrong hands with sensitive footage on it? Cryptocam uses age (X25519 and ChaCha20) to encrypt recorded videos and photos without ever persisting unencrypted data to device storage.

Use cases: - Attest the state of a Linux computer When your computer is in a trustworthy state, you can generate a private key hidden in the TPM2 of your computer. This private key can be sealed with the current state of the computer (PCRs). Then the computer can only sign a message with this key when it is in the correct state according to the PCRs. For example, you can seal the key against the secure boot state (PCR7). If your computer is booting an operating system signed by another vendor, the TPM2 cannot unseal the private key. So if your computer can generate a correct signature, it is in this known state. You can create a sealed private key and create such a signature with cryptographic-id-rs (https://gitlab.com/cryptographic_id/cryptographic-id-rs). This is similar to tpm2-totp (https://github.com/tpm2-software/tpm2-totp) but uses asymmetric cryptography. This means you do not need to keep the verification code secure. You can share it safely with the world. - Verify the identity of a phone You can generate a private key when your phone is in a trustworthy state. If your phone can create a correct signature, you know it is the same phone. Since the operating system can access the private key, the security guarantees are much weaker than with a TPM2. So the verification is just as secure as your phone. If you use Graphene OS, also have a look at Auditor (https://attestation.app/tutorial). - Verify that a person is in possession of a private key This works as well as the section above but has the same shortcomings. It can be used to verify someone in person when he sends his public key to you in advance over a secure channel.

DeadHash is an utility to calculate file and text hashes. The following hash calculations are supported: * MD5 * SHA-1 * SHA-224 * SHA-256 * SHA-3 * SHA-384 * SHA-512 * CRC32

Predicts pseudo random numbers based on a sequence of observed numbers. Enter a sequence of numbers that you obtained from a pseudo random number generator like, for instance, the Java standard pseudo random number generator or the Mersenne Twister MT19937. The app will then try to predict following numbers from the generator. The app expects all numbers to be entered as integers or floating point numbers between zero and one. Currently, floating point numbers are supported for the Mersenne Twister only. Three input modes are supported: 1. Text field lets you enter the numbers directly on the device. 2. File lets you choose a file with newline separated number strings. 3. Socket opens a server socket on the device. You can then connect with a custom client by means of a client socket and send newline separated number strings to the server. After each number the server will send back the next newline separated predictions. Each block of predictions is separated by an additional newline. To test the app, enter the following numbers in the Text field: 1412437139 1552322984 168467398 1111755060 -928874005 These numbers were sampled from the Java linear congruential generator Random.nextInt(). Thus, the app should detect LCG: Java after the third number input, and numbers in the prediction history should appear in green instead of red, indicating that those numbers were correctly predicted. The source code of this app is published on GitLab. There you can also find a Python program for testing socket input: https://gitlab.com/asnelt/derandom/blob/HEAD/README.md

Generate diceware passwords using the Reinhold, EFF (long) or EFF (short) wordlists, using the pseudo-random number generator on your device, random.org, or actual dice as sources of random numbers.

Description: File and text encryption in Android offers crucial benefits in protecting sensitive data. By encrypting files and text, users can prevent unauthorized access, ensuring confidentiality and privacy. This is especially vital in a world where mobile devices often contain personal, financial, and business-related information. Encryption adds an additional layer of security, preventing malicious actors from intercepting or tampering with data, thus mitigating the risk of data breaches and identity theft. Features: - Uses AES-256-GCM for encryption - Uses Scrypt for key derivation with CPU/Memory cost of 32768, block size of 16, and parallelization of 4 - Built in Java

DroidFS is an alternative way to use encrypted overlay file-systems on Android that uses its own internal file explorer instead of mounting volumes. This allows you to store files in encrypted vaults that other apps can't decrypt. Currently, DroidFS supports the following encrypted containers: - gocryptfs (https://github.com/rfjakob/gocryptfs): encrypts file contents and file names but doesn't hide directory structure or file sizes. - CryFS (https://github.com/cryfs/cryfs): slower, but encrypts everything and obfuscates file sizes. Features: - Compatible with original encrypted volume implementations - Internal support for video, audio, images, text and PDF files - Built-in camera to take on-the-fly encrypted photos and videos - Ability to expose volumes to other applications - Unlocking volumes using fingerprint authentication - Volume auto-locking when the app goes in background Permissions: Read & write access to shared storage: required to access volumes located on shared storage. Biometric/Fingerprint hardware: needed to encrypt/decrypt password hashes using a fingerprint protected key. Camera: required to take encrypted photos or videos directly from the app. Record audio: required if you want sound on videos recorded with DroidFS. Notifications: used to report file operations progress and notify about volumes kept open All of these permissions can be denied if you don't want to use the corresponding feature. DroidFS is free, open-source, and you can find the project's repository: - on GitHub: https://github.com/hardcore-sushi/DroidFS - on the Gitea instance of the Chapril project: https://forge.chapril.org/hardcoresushi/DroidFS Warning ! Security is neither absolute nor definitive. DroidFS does not come with any warranty and should not be considered as an absolute safe way to store files.

This app enables you to request and poll certificates from a SCEP (Simple Certificate Enrollment Protocol) server. It can be configured via MDM (Mobile Device Management) policies. Certificates can be automatically (silently) enrolled and renewed if delegated scope CERT_INSTALL is granted and SCEP connection details are configured via MDM/EMM. Plus it can be used as certificate selection app (private key mapping) if delegated scope CERT_SELECTION is granted, based on "cert-to-app" selection rules configured via MDM/EMM policy. It can also be used to monitor the expiration of your personal certificates and send you a notification a couple of days before. Additionally, it provides a manual Certificate Signing Request (CSR) creation feature and a PEM to PKCS12 converter.

With the introduction of the QUERY_ALL_PACKAGES permission, as far as I understand, it became impossible to use built-in tools to list and inspect installed packages. (Please let me know if you are aware of another workaround.) That is, of course, assuming you don't have access to root privileges. However, you might not desire to root your phone, either because it can turn out to be quite difficult to achieve, or because it has numerous disadvantages in itself, anyway. Another option is to connect to the phone via Android Debug Bridge (ADB) and run: adb shell dumpsys | sed -n '/^Packages:/,/^[[:space:]]*$/p' The command prints the "Packages" section from dumpsys, which contains detailed information about every installed package. It works, but the downside is obvious: You need an extra device to connect and run adb. This app strives to reproduce the output from above command, right on your phone - neither root privileges nor ADB required - using only API calls and the QUERY_ALL_PACKAGES permission.

I lost my new phone. And because I don't use Google Services I couldn't locate it and my phone was gone for good. In the hope that this doesn't happen again, I developed this application, so that I can locate the phone via SMS. Features: - Locate the device (using GPS or cellular location) - Lock the device - Let the device ring - Take pictures with the device's camera to see its surroundings - Factory-reset the device Usage: You can control FMD (and thus your phone) either via SMS or via FMD Server. You send a command to the phone (e.g. "fmd ring") and the phone executes it. For SMS you can either define a list of trusted contacts (phone numbers) that are allowed to send commands. Or you can set a PIN to allow anonymous usage. Then non-trusted phone numbers can also send commands by including the PIN in the message. This is useful because now if you lose your phone, you can ask a random person for help to wipe your phone remotely. If you simply text "fmd" to your phone FMD will reply with a text listing the available commands. With FMD Server you get a web interface to send commands, to view the location of your device on a map, and to view pictures taken by the device. You can self-host FMD Server. For more details, see: https://gitlab.com/fmd-foss/fmd-server Disclaimer: This app is provided on a best effort basis. We hope it is useful, we use it ourselves, but this is a hobby project and we can't guarantee that it will work when you need it the most.

FMD edge is the "cutting edge" version of FMD. FMD edge receives updates faster, more often, and slightly earlier than FMD. FMD edge releases are generally stable and ready for day-to-day use. FMD allows you to locate and remotely control your Android device. This is useful if you have lost or misplaced it. FMD is decentralised, and users remain in full control of their data. For more details about FMD, see the project website (https://fmd-foss.org/docs/overview) or the F-Droid listing for the main FMD app (https://f-droid.org/packages/de.nulide.findmydevice/).
