Stop Cyber Threats with VM-Series Next-Gen Firewall on Azure
Native application identity and user-based security for your Azure cloud
Gain integrated visibility across all traffic in a single pass. Deploy Palo Alto Networks VM-Series to determine application identity and content while automating security policy updates via rich APIs.
openSMS4 was created by tao.tang316 and implemented in C, which is an open source implementation of the SMS4 encryption algorithm (including simple checking codes).
Simple tool for file encryption and folder content encryption with AES 256. Files can also be hashed with a SHA1 signature. A command line version is available as well as a GUI version. One other useful feature is to encrypt messages for emails.
This is a more secure file encryption program which uses SERPENT cipher and WHIRLPOOL+SHA-256 hash functions in key creation and for integrity checking.
Secure File Transfer for Windows with Cerberus by Redwood
Protect and share files over FTP/S, SFTP, HTTPS and SCP with the #1 rated Windows file transfer server.
Cerberus supports unlimited users and connections on a single IP, with built-in encryption, 2FA, and a browser-based web client — all deployable in under 15 minutes with a 25-day free trial.
Cryptic is a cryptographic applications suite for encryption/decryption of data, calculating cryptographic hashes or message digests and securing user passwords using a master password in a password safe.
Encrypted Message Exchange by using Diffie-Hellman key exchange algorithm and Advanced Encryption Standard(AES) encryption algorithm with Cipher-block chaining(CBC) mode using User Datagram Protocol(UDP)port server-client application in C, Ansi-style
Rinecrypt uses the Gladman implentation of the AES algorithm
Rijndael and a SHA256 hash among other things, to encrypt/decrypt
a file with a user supplied passsword.
The IEEE 1619 Committee open-source reference implementations of encryption algorithms, plus testing and certification suites, for each encryption algorithm included in the standard.
With up to 25k MAUs and unlimited Okta connections, our Free Plan lets you focus on what you do best—building great apps.
You asked, we delivered! Auth0 is excited to expand our Free and Paid plans to include more options so you can focus on building, deploying, and scaling applications without having to worry about your security. Auth0 now, thank yourself later.
This its a simple project of the RSA algorithm. The purpose of this project isn't to develop an impressive program, it's an easy understand of the algorithm and the C programing.
The PowerCiph Data Encryption Algorithm is a versatile, yet simplistic, encryption algorithm/protocol. The ultimate goal of the algorithm is simplicity, compactness, and a lack of prerequisites.
Brute is a brute force hash cracker, it allows the user to specify how many threads he want running simultaneously. It is fast, and modular, all the hash algorithm dependent code lies in a module (a shared library). Modules available: MD5; SHA256; SHA512
Semeir is a Encryption algorithm, Capable of block encryption. It is written in pure C. It is platform independent, and is promising for Embedded systems. Intended as an alternate, yet secure data encryption cipher.
The Mav.Crypt tool will be upgraded to many different encryption methods. At the Moment, the only method is ROT13, but we are developing some other technics and a new Algorithm. More Infos shortly at the Project Web Page.
PHP Screw is a PHP script encryption tool. When you are developing a commercial package using PHP, the script can be distributed as encrypted up until just before execution, preserving your intellectual property.
Pseudo Random Number Generator (PRNG) frontend using libtomcrypt. It simply writes pseudorandom data (using sober-128, fortuna, yarrow or rc4 algorithm) on standard output. The output may be encoded to base64, base85 or hex or just left binary.
Figaro's Password Manager (FPM) is a GNOME application that allows you to securely store & categorize your passwords, which are encrypted using the blowfish algorithm. It can launch applications using the host names, user names, and passwords you supply.
B-Trust eDoc is a program built on top of LibDigiDoc a free implementation of the OpenXAdES standard for signing/encrypting files using smartcard tokens. It also contains Openssl and PKCS11 wrapper classes in C++ which might be useful to developers.
Real-Time Proactive Secret Sharing Library for RTAI is an implementation of the Shamir's secret sharing scheme and Herzberg's proactive secret sharing algorithm. The library uses a port of GNU GMP in order to make multiple precision arithmetic operatio
