HPN-SSH is a series of performance patches for OpenSSH. By addressing network limitations and CPU limitations significant throughput performance can be realized. Gains of close to two orders of magnitude are possible on long fat network paths. The official git repo is now available at http://github.com/rapier1/openssh-portable. The Sourceforge repository should not be seen as the canonical repository for HPN-SSH. We will update it as we can but users should look to github to generate patches We also support Ubuntu packages. Add them to your package manager with `sudo add-apt-repository ppa:rapier1/hpnssh` Fedora RPMs can be added with, `sudo dnf copr enable rapier1/hpnssh`

Largest Generic Hash and HMAC Program
57 Hash Functions In One Program, plus each with HMAC or KMAC
FEHASHMAC is the largest collection of publicly known hash algorithms integrated into a command-line utility. FEHASHMAC contains a set of known test vectors and results for each algorithm such that the correct implementation for each hardware platform and compiler version can directly be verified. Currently 57 hash algorithms like sha1 sha224 sha256 sha384 sha512 and variants, sha3 and shake, all SHA3 finalists and blake3, md2 md4 md5 md6, rmd128 rmd160 rmd256 rmd320, whirl gost lash160 lash256 lash384 lash512 tiger2 and RFC 2104 HMAC and KMAC support are included, plus SHA3 extensions kmac128, kmac256, kmacxof128, kmacxof256 for message. -

PGP Individual UID Signer makes signing all the UIDs on all of the keys at a PGP Keysigning party much simpler. It prompts for verification fingerprints, and then signs each UID on each key separately and PGP/Mime encrypt-emails them to their recipient. NOTE: Developement now happens at GitHub: http://github.com/jaymzh/pius

UPDATE 2024: Get a new version here: https://github.com/ivoras/EncryptedNotepad2 "Encrypted Notepad" does only one thing, but aims to do it perfectly - a Notepad-like simple text editor where files are saved (and later loaded) encrypted with industrial strength algorithms. Available both for the desktop (as a Java application) and on Android. Unencrypted data is never stored on-disk. Source is released (on SourceForge) under the BSD license.

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, security researchers, red teamers, digital forensics professionals, and CTF participants. -

Portable Text Encryption
Single Linux or Windows binary for secure text encryption
Self contained and completely portable binary encrypts text for secure email, messaging, irc use, etc., ideal for USB flash drives. AES-128/192/256 (ecb/cbc), Blowfish (ecb/cbc), DES / TripleDES (ecb/cbc/ofb/cfb), or RC4. Linux and Windows binaries. I don't make cute interfaces, it just works. https://codeberg.org/BloodFeastMan/pte I would also recommend FTC, encrypts both files and text using the same interface as PTE, and a separate encryption and hashing engine I wrote in Crystal, and is much faster than PTE: https://sourceforge.net/projects/ft-crypt/
