qrypto is a project aimed to provide simple, easy to use Blowfish encryption across popular languages for enhanced data security.

Combined coded remote-administrative service with SSL secure port scan, anonymous routing and third-party plugin inbuilt for quick and automatic "scan and install" process. Easy to use and will work under firewalls and up to 1024 bit strong cipher

a smal tool tat can split a file into to files for encryption only both files can restore the orginal file

This is rarbrute, a shell script to brute force encrypted rar files under unix and linux. A long wordlist and a paper about security in internet cafes is included.

Rex-SCA is a project which focus on the research in the field of Side Channel Attack, one hot issue of Crypto Analysis and Power Analysis attacks target the implementation of cryptographic devices. Rex is the project holder.

Tiny command line tool for speed optimized single file encryption/decryption.

Rijndog is an easy to use file encryption/decryption package making use of the Rijndael AES algorithm.

Ramos - McCain - RSA. Cryptographic tool based on the widely-known RSA public-key algorithm.

Rot13 decoder for cellphones (j2me).

RPC over SSL, server and client implementation

Linux console file encryption utility. Using tiger hash and rabbit cipher.

rtl2832_entropyd is a program that is designed to feed entropy into the linux /dev/random kernel entropy pool. It automatically forks and runs as a daemon, unless one of the testing options, -o or -t, are selected. Then it never forks. To use it, you need an rtl2832 USB dongle. They are relatively cheap (< $10 on ebay), and are actually used to listen to a broad range of radio transmissions. This application exploits the radio noise in the atmosphere to extract entropy. The kernel already has a module to use the rtl2832 for its intended purpose, listening to radio, so if you want to use it to generate entropy, you will have to blacklist that module, so it doesn't load. If it is loaded, this program will not be able to acquire the rtl2832 device, and won't run. Create the file /etc/modprobe.d/blacklist-dvb_usb_rtl28xxu.conf with the line blacklist dvb_usb_rtl28xxu in it. The project website is an html version of the man page, so you can find more complete information there.

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.

The iText based PDF sCramblEr allows you to encrypt a PDF using one or more public certificates of the addressees (one or more .cer files). For each .cer file, you can enforce specific PDF permissions: (dis)allow printing, (dis)allow modification,...

sIRC is a Secure IRC Communications Program, using MD5 Checksums and RC4 Cipher encryption.

Simple drag & drop file encryption tool. based on python and uses PyCrypto to encrypt the inputted files with AES encryption. Then sqlite database file is generated with a unique key to store the encrypted files and folders in binary blobs for later decryption.

Samizdat is a toolkit for Java for building Kerberos secured distributed, message-oriented applications. The toolkit contains base classes that simplifies the management of Kerberos login contexts as well as flexibly sign and seal messages between principals using the Java GSS API. The toolkit contains Transformation classes for Kerberizing JMS traffic as well as a super-lean HTTP based protocol stack that supports both Synchronous (RPC) and Asynchronous modalities.

sanesigner is a high level digital signature api component. it support generating and verifying digital signatures as well as encryption and decryption using public keys, and lots of other features in between.

Scrub-netflows is a multifield, multilevel Netflow log anonymizer written in perl.

Was a stream cipher attempt, but has been orphaned.

Secure and portable command-line password manager written in Java and based in the existing sf JRijndael project.

Using encryption to secure your code or text. Click File->Run to run your code using Ruby, see the pop up for output. Never save your text or code to disk unencrypted. Don't forget your password. Encryption is error-persistent.

sectar: a program that creates encrypted tape archives(tar files), using the AES algorithm Rijndael. Encryption exported under exemption TSU 740.13. Was star, now sectar.
