    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.

    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.

    dotNet Disk Imager

    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.

    aws-encryption-sdk

    aws-encryption-sdk

    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.
