Shasummer is a SHA hashsum utility in Java. It can calculate SHA1, SHA256 and SHA512 hashes of a file or of a directory (and its subdirectories) and verify the hashes later. Shasummer has a graphical and a command-line interface.

This tool will allow obfuscation of UNIX scripts listing an interpreter as the first line. It is most useful for distributing functionality in a commercial product or a high user volume environment where you wish to hide proprietary information.

Sirius-Sign is a signing and verification server with it's focus on high throughput and easy integration into an existinig landscape. For signature creation smartcards with OCF and PKCS11 interfaces are supported. An EJB container is required.

The Secure Java Code Filter (SJCF) provides an ICAP-based filter mechanism for mobile Java code and the signatures applied to it. Administrators can define a centralized policy determining which applications and signatures respectively are allowed.

The Stanford Javascript Crypto Library is a project by the Stanford Computer Security Lab to build a secure, powerful, fast, small, easy-to-use, cross-browser library for cryptography in Javascript. SJCL is small but powerful. The minified version of the library is under 6.4KB compressed, and yet it posts impressive speed results. SJCL is secure. It uses the industry-standard AES algorithm at 128, 192 or 256 bits; the SHA256 hash function; the HMAC authentication code; the PBKDF2 password strengthener; and the CCM and OCB authenticated-encryption modes. Just as importantly, the default parameters are sensible: SJCL strengthens your passwords by a factor of 1000 and salts them to protect against rainbow tables, and it authenticates every message it sends to prevent it from being modified. We believe that SJCL provides the best security which is practically available in Javascript.

SJEA version 1.0 - Simple Java Encryption Algorithm. SJEA is a simple command-line binary encryption algorithm (symmetric block cipher) written in JAVA. It uses a password and a byte-vector array to scramble the input file.

SLEncrypt is a python module for encryption with 11 ciphers at the moment, including ADFGVX, Autokey, Caesar/ROT13, Vigenere, XOR and a lot more. It contains functions allowing you to easily encrypt/decrypt files. The code is about 95% PEP 8 compilant.

the "Simple Password Displayer" is a multiuser password managing software based on GnuPG, so every user has his own password to decrypt/sign the container.

spule stands for "secure practical universal lecture evaluator". spule is a program to automatize the evaluation of lecture polls.

ssh host keyserver: extends the pgp web of trust to ssh host keys.

The ssh-utils package provides tools and extensions for the application of SSH. Current contained tools: - ssh-agent-manage.sh The management of the parallel SSH access by multiple agents, sessions, and keys. - ssh-pk-type.sh Displays private key type. - ssh-pk-asn1.sh Displays the private key as ASN.1.

Stegeek is very simple tool, that takes several files,encrypt, and mix them into one file. Also add some redundancy. The result is, that we have one archive and N keys. It should not be possible to guess N, if you have archive and up to N-1 keys.

Note: this is alpha-quality software, and isn't ready for production use. STROBE is a lightweight framework for cryptographic protocols. It supports encryption/decryption, hashing, pseudorandom generation and message authentication. It integrates these components in an innovative way that makes secure protocol design relatively simple. With the included elliptic curve code, STROBE additionally supports asymmetric key exchange and digital signature creation and verification.

OSX Application to keep notes and information safe under 448 bit blowfish encryption system. The application is in beta stage, with some major bugs around. You are advised to verify the bug list.

talkLock is voice encryption software for your cell phone. talkLock includes a server component so that you own all points of encryption and decryption of your communications.

Tcpconns:simple package for rapid development of multi-threaded client/server solutions (JAVA OpenJDK17+) with TLS (V1.3).

A SecureTicket, or Ticket, consists of salt, hash, valid_until, public_flags, flags, data and "invisible" hashed entropy. Tickets are symmetrically signed using SHA256-HMAC. Fields 'valid_until', 'flags' and 'data' may be optionally encrypted using AES128-CBC or TripleAES128-CBC. Values 'data' and 'entropy' may consist of arbitrary objects which are transparently pickled(serialized), optionally gzipped and of course securely signed. Specific implementations are included: FormTicket: provides core implementation of state-less Cross Site Request Forgery protection. Other use cases include ticketing object param values pointing at URL:s or services in HTML-objects such as Flash or Java Applets. This adds server-side choises to be made while preventing users from using arbitrary values. Severe testing is done and will be mandatory for core and every specific implementation. Every single bit is flipped and various ticket contents and flag combinations are permutated.

tinySSO is a simple Single Sign-On in Java based on a secure cookie protocol.

A PHP-GTK based GUI for truecrypt on linux. Requires PHP cli with PHP-GTK2 installed to run.

a php/js library used for serverside/client side password encryption, ment to mask the password sent by login forms.

Being that Sun\'s Java Cryptography Extension (JCE) is not well-documented and has a steep learning curve, the vH Crypto API for Java is being created to abstract the procedures which are commonly used in cryptography.

For details of this cipher see; http://en.wikipedia.org/wiki/Vigenere_cipher This cipher can be broken by frequency analysis, this is a toy project, and should not be used in situations where security is important.

WEB-interface for Public key Infrastructure.

A quick and easy to use SHA1 calculator for Windows, using C# & .net. (very) Similiar in style to winMD5Sum; supports filenames passed on the command line & files drag+dropped on!

It load the current public-timestamp-block from publictimestamp.org and store it in a file to use it e.g. as a signature in an e-mail software. The project is inactive and not under development anymore.
