    Stegcore

    Stegcore

    A cross-platform crypto-steganography toolkit

    Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there. Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible. Designed for journalists,...

    1654 — encryption system

    1654 — encryption system

    1024-bit encryption system (functional safe or disk) | С++20

    This release marks the first production-ready publication of 1654, a dependency-free cryptographic vault engine built around a strict vault abstraction and a wide-state cryptographic design. 1654 is not a wrapper around existing crypto libraries. It is a self-contained system whose cryptographic behavior is fully defined within the repository. Key Characteristics Vault-oriented model Encrypted data is treated as a sealed container-safe with explicit operations, not as a password-wrapped file. Dependency-free design The entire cryptographic surface is auditable in-tree. ...

    OTP-Crypto-Tool

    Symetric file encryption based on OTP implemented as XOR encryption

    OTP (One Time Pad) In case you have any questions, contact me at: crypto-munition@gmx.de When used correctly, the OTP is an information-theoretically secure and demonstrably non-breakable encryption. The encryption process is implemented as symmetrical file encryption based on XOR encryption. The integrated pseudo-random generator serves only to illustrate and check the functionality. The use of this generator for REAL OTPs is not recommended.

    Wipe erase data from hdds on the network, unlimited hard disks

    Automated network based hard disk drives / storage devices erasure is server based software which installs on a central server. Server is connected to network switches and several PXE boot enabled workstations are attached to the network. As soon as the workstation is powered on, it boots off the network via the server and begins wiping all the attached hard disk drives. Once all the hard drives are wiped, data related to each hard disk is stored in the central server’s database. Read...

    pyWhat is a Python-based identification tool designed to figure out “what” a piece of text or file content represents, especially in security and OSINT workflows. Given inputs such as hex strings, URLs, email addresses, IP addresses, credit card numbers, cryptocurrency wallets, or entire .pcap capture files, it scans for structured patterns and tells you what it finds. The tool is recursive: it can traverse files and directories to extract meaningful entities, which is useful when analyzing...

    OpenSK

    OpenSK

    OpenSK is an open-source implementation for security keys

    ...It provides the full authenticator stack—USB/NFC transport, CTAP protocol handling, credential management, and cryptographic operations—so you can build and audit your own hardware token. The project emphasizes defense-in-depth: memory-safe Rust, hardened crypto, isolation via an embedded OS, and explicit user presence/verification flows. Developers can flash reference hardware, customize UX (LEDs, buttons, PIN), and experiment with extensions while staying interoperable with major browsers and platforms. A test and conformance suite validates protocol behavior against the WebAuthn/CTAP specs to ensure compatibility.

    Split your file into encrypted fragments

    ...It’s especially aimed at people who want strong security for sensitive large files and want to avoid remembering complex pass-codes, and also those who may distribute fragments across multiple locations. The logic is built on Go’s crypto libraries and the underlying Shamir implementation, with an emphasis on simplicity and security rather than password-based keying.
