    Swift Crypto

    Swift Crypto

    Open-source implementation of a substantial portion of the API

    Swift Crypto is a cross-platform, open-source implementation that mirrors a substantial portion of CryptoKit so server and Linux/Windows ARM64 apps can share one modern crypto API. It exposes high-level, misuse-resistant primitives with Swift ergonomics while delegating to well-vetted backends under the hood. The repository maintains active releases and issue tracking for enhancements like PEM handling and ecosystem compatibility. High-level, misuse-resistant primitives and key handling. SwiftPM distribution for easy inclusion in builds. By matching CryptoKit’s surface, it reduces portability friction between Apple platforms and server environments. The package slots cleanly into SwiftPM builds and is widely adopted across the Swift server ecosystem. Its goal is practical cryptography: safe defaults, clear APIs, and predictable performance.

    s2n-quic

    s2n-quic

    An implementation of the IETF QUIC protocol

    s2n-quic is AWS’s open-source implementation of the IETF QUIC transport protocol, written in Rust and designed for performance, security, and modern usage. QUIC is a UDP-based, multiplexed, encrypted transport layer that underpins HTTP/3 and addresses issues such as head-of-line blocking and faster handshake times compared to TCP+TLS. This library integrates with AWS’s s2n-tls or rustls for the TLS 1.3 handshake and leverages Rust’s memory and thread safety guarantees to deliver a robust implementation. It is built with configurability in mind—you can tune congestion control (like CUBIC), pacing, packet size discovery, and other advanced network behaviors. Extensive testing (unit, fuzz, interop) ensures protocol compliance and interoperability with other implementations. Because it is open-source under Apache 2.0, organizations can integrate it into services where low latency, multiple streams, or mobility (connection migration) matter.

    denuvo

    DENUVO (VMProtect 2.6x) VM research tool

    This is part of the original source code of DENUVO_Profiler, written by 386 Team in 2014-2017 to investigate the first versions of DENUVO (eq VMProtect 2-3), when there were no lifters and other modern devirtualisation tools. DENUVO_Profiler is a subsequent development of the SecuROM_Profiler utility - the simplest tool for visualising the operation of a virtual machine and effectively controlling the data it uses in the byte-code tape (p-code). DENUVO_Profiler also hunts for Electronic Arts (Origin) licence containers on the current user's machine and can extract their contents, with including the GameToken. # See also: 80_PA SecuROM keygen

    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.

    Amazon DynamoDB Encryption Client Python

    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.

    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.

    Client-side Encryption Amazon DynamoDB

    Client-side Encryption Amazon DynamoDB

    Amazon DynamoDB Encryption Client for Java

    The Amazon DynamoDB Client-side Encryption in Java supports encryption and signing of your data when stored in Amazon DynamoDB. A typical use of this library is when you are using DynamoDBMapper, where transparent protection of all objects serialized through the mapper can be enabled via configuring an AttributeEncryptor. Use SaveBehavior.PUT or SaveBehavior.CLOBBER with AttributeEncryptor. If you do not do so you risk corrupting your signatures and encrypted data. When PUT or CLOBBER is not specified, fields that are present in the record may not be passed down to the encryptor, which results in fields being left out of the record signature. This in turn can result in records failing to decrypt. For more advanced use cases where tighter control over the encryption and signing process is necessary, the low-level DynamoDBEncryptor can be used directly.
