    SOPS

    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.

    Ciphey

    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

    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 for Java
    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.

    MemGuard

    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

    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.

    aws-encryption-sdk-cli

    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.

    sjcl

    Stanford Javascript Crypto Library

    The Stanford Javascript Crypto Library is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript. SJCL is small but powerful. The minified version of the library is under 6.4KB compressed, and yet it posts impressive speed results. SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes. Just as importantly, the default parameters are sensible: SJCL strengthens your passwords by a factor of 1000 and salts them to protect against rainbow tables, and it authenticates every message it sends to prevent it from being modified. We believe that SJCL provides the best security which is practically available in Javascript.

    NTK Ultra-Compression

    NTK Ultra-Compression

    Logiciel de compression de fichiers maximal indépendant du temps.

    Le logiciel NTK Ultra-Compression répond à une problématique essentielle de l’ère numérique : comment réduire la taille des données à leur minimum absolu sans compromis sur leur intégrité, tout en s’affranchissant des contraintes temporelles ? Dans un monde où les volumes de données explosent et où les solutions actuelles de compression restent limitées par des compromis entre rapidité, efficacité et complexité, nous proposons une approche disruptive. Les solutions actuelles, telles que le format ZIP ou 7z, bien qu’efficaces, atteignent leurs limites en termes de taux de compression et d’efficacité pour les fichiers volumineux ou complexes. Ces outils sont souvent contraints par des compromis entre rapidité d’exécution et efficacité de stockage. Cette approche disruptive s’adresse notamment aux utilisateurs ayant besoin de manipuler des fichiers volumineux, comme les logiciels, les jeux vidéo ou les bases de données, où chaque octet économisé compte.

    ISC - The ISAAC Stream Cipher

    ISC - The ISAAC Stream Cipher

    ISC lets you encrypt & decrypt text and files of any type up to 4GB

    ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity. ISC is a symmetric key encryption system, which means that both the sender and recipient of a message must possess the key.
