PasswordBox
A console-mode program that will keep all your passwords safe
PasswordBox is a console-mode program that will keep all your passwords safe, in an encrypted database protected by a master password. PasswordBox can also be used to generate secure (random) passwords. This program is written by Mateusz Viste, and uses the AES implementation of Chris Brown to handle all encryption/decryption processes. PasswordBox is available for the following operating systems: DOS, Windows, Linux. Remember, that if you forget your master password, you will have no way to recover the database content. Usage: pbox [--help] [--dump] --help displays a help screen (any unsupported parameter will display it, too) --dump lists all the data of your encrypted database onscreen -

ISC - The ISAAC Stream Cipher
ISC lets you encrypt & decrypt text and files of any type up to 4GB
ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity. ISC is a symmetric key encryption system, which means that both the sender and recipient of a message must possess the key. -

Azrar
Encryption addressing long-term data secrecy
Most of today's cryptographic standards will be broken with tomorrow's computational power. Azrar is a user-friendly tool for the encryption/decryption of single files - preferably compressed archives - addressing long-term data secrecy. Thus, Azrar provides the possibility to use webspace for secure data transfer between two communication/transfer partners (encryption only, network transfer not yet included in current version). Data in encrypted files are secret/private indefinitely. To achieve long-term data secrecy, Azrar differs from other approaches in terms of not to rely on effective computational deficiencies. It combines a one-time pad with a stream cipher method using the strong cryptographic hash function (family) Skein. Azrar fulfills business requirements for secure data transfer and supports several operating systems natively. It does not use a runtime environment. -

Bigram Table Generator
A program to generate random reciprocal bigram tables
A command-line program to encrypt/decrypt a message using a random reciprocal bigram table and write a bigram table to a text file. Executing the program without any command-line arguments starts bigram in message encryption/decryption mode. The program prompts for a password or passphrase and a message to encrypt/ decrypt. After the message is entered the ciphertext is displayed. Executing the program with command-line arguments causes bigram to generate a random bigram table to print to screen or save to disk depending on whether the -f filename argument was given. If the -p passphrase argument is given a specific table is generated and is repeatable each time the same passphrase is given. This program was written to supplement the Enigma Simulator by Dirk Rijmenants. http://users.telenet.be/d.rijmenants/en/enigmasim.htm Enigma message procedures: http://users.telenet.be/d.rijmenants/en/enigmaproc.htm -

FMSec - File Manager Security
Security Extensions to File Managers
FMSec (File Manager SECurity) is a set of extensions to file managers that enable some security-related operations to be easily performed. The operations are: - encryption and decryption using OpenSSL (https://www.openssl.org/), - safe removing (shredding) files and directories (recursively), - mounting and unmounting TrueCrypt and VeraCrypt (https://www.veracrypt.fr/en/) volumes, - wiping the free space on a filesystem using WipeFreeSpace (https://wipefreespace.sourceforge.io/), - running programs with LibSecRm (https://libsecrm.sourceforge.io) preloaded, - running programs with LibHideIP (https://libhideip.sourceforge.io) preloaded, - running programs with LibNetBlock (https://libnetblock.sourceforge.io) preloaded, - generating digital certificates (X.509 / SSL / TLS / PKCS#12 / P12).

SES Super-Encypherment Scrambler
SES brings back the uncrackable onetime pad, with a digital twist.
SES brings back the uncrackable onetime pad, with a digital twist. It is well known that a random key of message-length is the only provably unbreakable cipher. SES uses cryptographic strength pseudo-random keys of message-length for its many encipherments, in addition to offering true one-time pad capability for the intrepid. SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to efficiently cipher text of arbitrary length or files of any size or type. Use it with confidence. To achieve complete one-on-one privacy, SES traverses several levels en route to its output. The more words in your key-phrase, the more layers of encipherment SES applies. It is part Vigenere, part onetime pad, part cryptographic hash, not to mention the essential scrambler element, each component driven by ISAAC, with all key-derivation and stretching relying on Keccak in 512-bit configuration. -

StrongKey CryptoCabinet
FIDO-enabled, cloud file encryption with centralized key management.
StrongKey CryptoCabinet (SKCC) 2.0 is a FIDO-enabled (fidoalliance.org) web application built using Regulatory Compliant Cloud Computing (RC3) architecture (http://bit.ly/rc3infoq). It encrypts files/objects of any type or size, and stores the ciphertext either to public/private clouds—AWS, Azure, Eucalyptus—or local/network drives, while keeping cryptographic keys safe and secure OUTSIDE the cloud. CryptoCabinet leverages the StrongKey CryptoEngine (SKCE)—another FOSS on this site—to perform FIDO U2F strong authentication, encryption/decryption, digital signatures, and cloud integration. CryptoCabinet is a powerful example showcasing StrongKey CryptoEngine's innovative capabilities. Until you modify the CryptoEngine configuration, the default download uses a DEMO Tellaro KeyAppliance (KA) instance to store cryptographic keys. As such, use this ONLY FOR DEMO purposes. Contact us for any of your production needs. Thanks for stopping by! -
