VeraCrypt
Open source disk encryption with strong security for the Paranoid
VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html -

AWS Encryption SDK for Java
AWS Encryption SDK
The AWS Encryption SDK is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It enables you to focus on the core functionality of your application, rather than on how to best encrypt and decrypt your data. The AWS Encryption SDK is provided free of charge under the Apache 2.0 license. With the AWS Encryption SDK, you define a master key provider (Java and Python) or a keyring (C, C#/.NET, and JavaScript) that determines which wrapping keys you use to protect your data. Then you encrypt and decrypt your data using straightforward methods provided by the AWS Encryption SDK. The AWS Encryption SDK does the rest. Without the AWS Encryption SDK, you might spend more effort on building an encryption solution than on the core functionality of your application. By default, the AWS Encryption SDK generates a unique data key for each data object that it encrypts. -

SOPS
Simple and flexible tool for managing secrets
sops is an editor of encrypted files that supports YAML, JSON, ENV, INI and BINARY formats and encrypts with AWS KMS, GCP KMS, Azure Key Vault, age, and PGP. For the adventurous, unstable features are available in the develop branch, which you can install from source. To use sops as a library, take a look at the decrypt package. We rewrote Sops in Go to solve a number of deployment issues, but the Python branch still exists under python-sops. We will keep maintaining it for a while, and you can still pip install sops, but we strongly recommend you use the Go version instead. If you're using AWS KMS, create one or multiple master keys in the IAM console and export them, comma separated, in the SOPS_KMS_ARN env variable. It is recommended to use at least two master keys in different regions. If you want to use PGP, export the fingerprints of the public keys, comma separated, in the SOPS_PGP_FP env variable. -

Amazon DynamoDB Encryption Client Python
Amazon DynamoDB Encryption Client for Python
The Amazon DynamoDB Encryption Client for Python provides client-side encryption of Amazon DynamoDB items to help you to protect your table data before you send it to DynamoDB. It provides an implementation of the Amazon DynamoDB Encryption Client that is fully compatible with the Amazon DynamoDB Encryption Client for Java. The helper clients provide a familiar interface but the actual item encryption and decryption is handled by a low-level item encryptor. You usually will not need to interact with these low-level functions, but for certain advanced use cases it can be useful. If you do choose to use the item encryptor functions directly, you will need to provide a CryptoConfig for each call. By default, the helper clients use your attribute actions and cryptographic materials provider to build the CryptoConfig that is provided to the item encryptor. For some advanced use cases, you might want to provide a custom CryptoConfig for specific operations. -

dotNet Disk Imager
Lightweight RAW and ZIP disk images reader and writer to USB or SD
IMPORTANT!!! Since this is new software, your web browser, operating system or even possibly antivirus software may report security alerts against this tool. Please ignore that messages until this tool gets widely spread. This program is highly inspired by Win32 Disk Imager and sort of copies it's function. However, I've added some features, like verification of readed/writed image file and the most important is on the fly support for zipped images. Another features worth mentioning are simultaneous write to multiple devices at one time or wiping of device filesystem and partitions. I would be happy to hear your feedback and I'm ready to listen to your suggestions. Feel free to request new features, if I found them interesting I will definitely implement them. Requires .NET Framework 4.6.1 (download here: http://go.microsoft.com/fwlink/?LinkId=671729 ) Supports Windows 7 and newer. If you need older Windows support, use Win32 Disk Imager. Please write a review. -

Ciphey
Decrypt encryptions without knowing the key or cipher
Fully automated decryption/decoding/cracking tool using natural language processing & artificial intelligence, along with some common sense. You don't know, you just know it's possibly encrypted. Ciphey will figure it out for you. Ciphey can solve most things in 3 seconds or less. Ciphey aims to be a tool to automate a lot of decryptions & decodings such as multiple base encodings, classical ciphers, hashes or more advanced cryptography. If you don't know much about cryptography, or you want to quickly check the ciphertext before working on it yourself, Ciphey is for you. The technical part. Ciphey uses a custom-built artificial intelligence module (AuSearch) with a Cipher Detection Interface to approximate what something is encrypted with. And then a custom-built, customizable natural language processing Language Checker Interface, which can detect when the given text becomes plaintext. -

AWS Encryption SDK for C
AWS Encryption SDK for C
The AWS Encryption SDK for C is a client-side encryption library designed to make it easy for everyone to encrypt and decrypt data using industry standards and best practices. It uses a data format compatible with the AWS Encryption SDKs in other languages. For more information on the AWS Encryption SDKs in all languages, see the Developer Guide. We will demonstrate some simple build recipes for Linux, Mac, and Windows operating systems. These recipes assume a newly installed system with default installs of dependency packages. The Windows instructions install everything in your current directory (where you run the build process). The AWS Encryption SDK for C can be used with AWS KMS, but it is not required. For best results when doing a build with AWS KMS integration, do not install aws-c-common directly. Build and install the AWS SDK for C++, which will build and install aws-c-common for you (see the C++ SDK dependencies here). -

aws-encryption-sdk-cli
CLI wrapper around aws-encryption-sdk-python
This command line tool can be used to encrypt and decrypt files and directories using the AWS Encryption SDK. If you have not already installed cryptography, you might need to install additional prerequisites as detailed in the cryptography installation guide for your operating system. Installation using a python virtual environment is recommended to avoid conflicts between system packages and user-installed packages. For the most part, the behavior of aws-encryption-cli in handling files is based on that of GNU CLIs such as cp. A qualifier to this is that when encrypting a file, if a directory is provided as the destination, rather than creating the source filename in the destination directory, a suffix is appended to the destination filename. By default the suffix is .encrypted when encrypting and .decrypted when decrypting, but a custom suffix can be provided by the caller if desired. -

A pronounceable password generator plugin for KeePass. NOTE: This project has been discontinued. It hasn't been worth it to maintain the project for a while now, so no more updates will be made to the plugin. The algorithm this plugin uses is based off FIPS-181 which was withdrawn by NIST a while back. The proliferation of password managers that seamlessly run on multiple platforms (some of which are free) has also removed almost all advantages of using randomly generated pronounceable passwords. If you have a use case for this plugin, reconsider it. If you still think using randomly generated pronounceable passwords are worth it for your use case, reconsider it some more.

Ente
End-to-end encrypted cloud for photos, videos and 2FA secrets
Ente is a fully open-source, end‑to‑end encrypted cloud platform designed for securely storing and managing your photos, videos, and 2FA secrets — without needing to trust the service provider. It includes cross‑platform clients and a CLI for self‑hosting needs. Ente is a service that provides a fully open source, end-to-end encrypted platform for you to store your data in the cloud without needing to trust the service provider. On top of this platform, we have built two apps so far: Ente Photos (an alternative to Apple and Google Photos) and Ente Auth (a 2FA alternative to the deprecated Authy). This monorepo contains all our source code - the client apps (iOS / Android / F-Droid / Web / Linux / macOS / Windows) for both the products (and more planned future ones!), and the server that powers them. -

MemGuard
Secure software enclave for storage of sensitive information in memory
This package attempts to reduce the likelihood of sensitive data being exposed when in memory. It aims to support all major operating systems and is written in pure Go. Sensitive data is encrypted and authenticated in memory with XSalsa20Poly1305. The scheme used also defends against cold-boot attacks. Memory allocation bypasses the language runtime by using system calls to query the kernel for resources directly. This avoids interference from the garbage collector. Buffers that store plaintext data are fortified with guard pages and canary values to detect spurious accesses and overflows. The effort is taken to prevent sensitive data from touching the disk. This includes locking memory to prevent swapping and handling core dumps. Kernel-level immutability is implemented so that attempted modification of protected regions results in an access violation. -

transfer.sh
Easy and fast file sharing from the command-line
Easy and fast file sharing from the command-line. This code contains the server with everything you need to create your own instance. Transfer.sh currently supports the s3 (Amazon S3), gdrive (Google Drive), storj (Storj) providers, and local file system (local). For easy deployment, we've created a Docker container. For the usage with a AWS S3 Bucket, you just need to specify the following options, provider, aws-access-key, aws-secret-key, bucket, and s3-region. If you specify the s3-region, you don't need to set the endpoint URL since the correct endpoint will used automatically. To use a custom non-AWS S3 provider, you need to specify the endpoint as defined from your cloud provider. In preparation you need to create an access grant (or copy it from the uplink configuration) and a bucket. To get started, login to your account and go to the Access Grant Menu and start the Wizard on the upper right. -

BIP39-XOR
Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array ("seed")
Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array (so-called "seed phrase") using exclusive OR (XOR)/Vernam cipher (a.k.a. One Time Pad). If not input by a user, an encryption key is automatically generated at random. Encryption with such a key preserves integrity of BIP-39 checksums of all keys (that's distinct while also compatible with SeedXOR implementation). -

age
A simple, modern and secure encryption tool (and Go library)
age is a security-oriented tool and library by Filo Sottile. age is a simple, modern, secure encryption utility (and Go library) that emphasizes minimal configuration and strong defaults. It provides small explicit keys, no complex options, and is designed for UNIX-style composability; you can pipe into it, integrate it into scripts, etc. It supports a clearly defined format and promotes interoperability across implementations (there are Rust, TypeScript, etc). The project is well-suited for personal data encryption, backup use-cases, scripting encryption workflows, and embedding encryption in tools. Because of its design philosophy, it avoids the bloat of many older encryption utilities while maintaining strong cryptographic hygiene. It’s especially useful for developers or system administrators who want to adopt encryption without learning a multitude of options.
