Cryptomator offers multi-platform transparent client-side encryption of your files in the cloud. Most cloud providers encrypt data only during transmission or they keep the keys for decryption for themselves. These keys can be stolen, copied, or misused. With Cryptomator, the key to your data is in your hands. Cryptomator encrypts your data quickly and easily. Afterwards you upload them protected to your favorite cloud service.
Devv.Core.Crypto is an encryption library written in VB.NET. It supports all the major Cipher and Hash algorithms: RC2, DES, TripleDES, AES (Rijndael), SHA and MD5. The configuration can be done using the application settings file, and it's quite easy to integrate. Compatible ...
We demonstrate an attack on the secure bootchain of the Nintendo 3DS in order to gain early code execution. The attack utilizes the block shuffling vulnerability of the ECB cipher mode to rearrange keys in the Nintendo 3DS's encrypted keystore. Because the shuffled keys will deterministically decrypt the encrypted firmware binary to incorrect plaintext data and execute it, and because the device's memory contents are kept between hard reboots, it is possible to reliably reach a branching instruction to a payload in memory. This payload, due to its execution by a privileged processor and its early execution, is able to extract the hash of hardware secrets necessary to decrypt the device's encrypted keystore and set up a persistent exploit of the system. Information in this article (especially the keyshuffling vulnerability) is original, independent work unless cited otherwise. Note that the keyshuffling vulnerability detailed here is the same one documented publicly by much of this team including "stuckpixel" (also known as "dark_samus") on sites such as 3DBrew. Additionally, note that the persistence vulnerability detailed here is the same one documented publicly as "arm9loaderhax" by "plutoo", "derrek", and "smea" at the 2015 32c3 conference.
Themis is open-source high-level cryptographic services library for mobile and server platforms, providing secure messaging and secure data storage. Themis provides three important cryptographic services Secure messaging, Secure session and Secure storage.
Example #1 — Old Station: view comparison in 24-bit HD, original photo CC-BY-SA @siv-athens. As seen on TV! What if you could increase the resolution of your photos using technology from CSI laboratories? Thanks to deep learning and #NeuralEnhance, it's now possible to train a neural network to zoom in to your images at 2x or even 4x. You'll get even better results by increasing the number of neurons or training with a dataset similar to your low resolution image.
Orion is a cryptography library written in pure Rust. It aims to provide easy and usable crypto while trying to minimize the use of unsafe code. You can read more about Orion in the wiki. This library has not undergone any third-party security audit. Usage is at own risk.
These are basic implementations of standard cryptography algorithms, written by Brad Conte (firstname.lastname@example.org) from scratch and without any cross-licensing. They exist to provide publically accessible, restriction-free implementations of popular cryptographic algorithms, like AES and SHA-1. These are primarily intended for educational and pragmatic purposes (such as comparing a specification to actual implementation code, or for building an internal application that computes test vectors for a product). The algorithms have been tested against standard test vectors. This code is released into the public domain free of any restrictions. The author requests acknowledgement if the code is used, but does not require it. This code is provided free of any liability and without any quality claims by the author.
Hat.sh is a web app that provides secure file encryption in the browser. It's fast, secure and runs locally, the app never uploads the files to the server. It uses modern secure cryptographic algorithms with chunked AEAD stream encryption/decryption. The libsodium library is used for all cryptographic algorithms.
