Custom VMs From 1 to 96 vCPUs With 99.95% Uptime
General-purpose, compute-optimized, or GPU/TPU-accelerated. Built to your exact specs.
Live migration and automatic failover keep workloads online through maintenance. One free e2-micro VM every month.
Perfenc is a encryption program that encrypts/decrypts files or the standard input with a one-time pad.
More information about one-time pads is available at http://en.wikipedia.org/wiki/One-time_pad
ShredBitz is a free and simple file shredder tool that can wipe selected files from any hard disk drive. ShredBitz is written in the java programming language and uses a custom written algorithm for shredding.
ShredBitz is a very powerful tool.
This project aims at porting visual cryptography, which only works with transparent slides, to ordinary 80g/m^2 white paper. Please read the documentation before using the program.
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.
New customers can spin up VMs, build with AI, and query data at no cost.
Put your $300 in credit toward real workloads, then keep building with free monthly usage for 20+ products. No commitment and no charge until you upgrade.
A web-based system to assign a set of known persons anonymous ids, such that every person only receives one id. The ids cannot be mapped to the corresponding persons afterwards.
Kotak is just another cracking tool which is based on Java. It is used to crack various types of hash functions with various types of attacks. It's developed to be as simple as possible, so that anyone can use this tool easily.
Derived from TrueCrypt 6.3 release, I added some command line options to "TrueCrypt Format.exe" to allow TrueCrypt volumes to be created without using the graphical user interface
a perl script to perform Vigenere (polialphabetic enciphering and deciphering) for teaching classes. Keys are stored in a dedicated file in order to have a one time pad to use for messages exchange.
This is a simple encryption tool to work with home-grown encryption algorithms.
It can run as either a GUI, a command-line application, or a network proxy.
A Javascript implementation of the Blowfish Encryption Algorithm described by Bruce Shneier circa 1993. Blowfish is a keyed, symmetric block cipher common in cipher suites and was placed, by Mr. Shneier, in the public domain.
BBSGen is an improved Blum-Blum-Shub pseudorandom number generator. It consists of a C library (libbbsgen) and command-line tool (bbsgen). BBSGen can be used in applications and command-line as secure, unpredictable and strong PRNG.
Allows to transparently encrypt repository contents with AES 256. The main advantage is that no additional software needed to be installed in untrusted location. Files are automatically encrypted on the fly when doing git push from trusted location.
Kryptographie is a student project to implement historic encryption methods. It has a linux style command line interface. This project will also include the notes for my talk I'll hold on cryptography in school. (in German).
Utility to encrypt files and streams. Features: encryption with AES, Serpent, Twofish and many other block ciphers supported by Botan; PBKDF2 key derivation; HMAC verification; does not require files, works with pipe input and output
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.
A more modern wiki focusing on open technologies like SOAP and XML, and upon a more focused form of wiki software that incorporates the elements of traditional content creation, such as from journals, books or periodicals.
Software solution for creation and verification of digitral signatures. Can replace tokens and smart cards with mobile phones. Components included are client and server. Can creates, verifiy and store content and signatures. Offers secure sharing.
A pure python module which implements the DES and Triple-DES encryption algorithms. Triple DES is either DES-EDE3 with a 24 byte key, or DES-EDE2 with a 16 byte key.
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.
DCrypt is an encryption and decryption tool that combines in a smart way multiple algorithms. The combination of multiple strong algorithms makes it much more difficult for hackers to get the plain content of the encrypted file without the password.
