    GnuPG

    GnuPG

    Complete and free implementation of the OpenPGP standard

    GnuPG (GNU Privacy Guard) is a widely used free software encryption system that implements the OpenPGP standard to provide secure communication and data protection across multiple platforms. It uses a hybrid cryptographic approach combining symmetric encryption for performance with public-key cryptography for secure key exchange and identity verification. The software allows users to encrypt files and messages, create digital signatures, and manage cryptographic keys, making it a foundational tool for privacy-focused workflows. Because it is open source and licensed under the GNU GPL, GnuPG can be freely audited, modified, and redistributed, which has contributed to its adoption in security-sensitive environments. ...

    Minisign

    Minisign

    A dead simple tool to sign files and verify digital signatures

    Minisign is a lightweight command-line utility designed for generating and verifying digital signatures with a strong focus on simplicity, security, and portability. It uses the modern Ed25519 public-key cryptographic system to produce fast and compact signatures, making it well-suited for software distribution and file integrity verification. The tool is intentionally minimalistic, performing a single task efficiently without unnecessary complexity, which makes it easy to integrate into automated workflows and pipelines. Users can generate key pairs, sign files, and verify signatures using straightforward commands, enabling secure validation of files across different environments. ...

    Defeating Windows user account control

    Run executable from command line, akagi32 [Key] [Param] or akagi64 [Key] [Param]. First parameter is a number of methods to use, second is an optional command (executable file name including full path) to run. The second parameter can be empty - in this case, the program will execute elevated cmd.exe from the system32 folder. Since 3.5.0 version all "fixed" methods are considered obsolete and removed altogether with all supporting code/units.

    Hash Latch
    ...But that alone would've been too easy to hack. To prevent an attacker from forging the keys by generating a new prefix: the hash latch doesn't output the keys in the plaintext. Instead, it encrypts the key and outputs the ciphertext. That means that instead of giving you the actual key, it gives you a safe containing the key. This approach allows the hash latch to protect itself from forged keys and also enables you to put the same key into multiple safes without the recipients of these safes knowing they have the same key (even if they compare their ciphertexts). ...

    SSH man-in-the-middle tool

Of course, the victim's SSH client will complain that the server's key has changed. But because 99.99999% of the time this is caused by a legitimate action (OS re-install, configuration change, etc), many/most users will disregard the warning and continue on. NOTE: Only run the modified sshd_mitm in a VM or container! Ad-hoc edits were made to the OpenSSH sources in critical regions, with no regard to their security implications. ...
