Application which allows encrypting text. It is encrypted using own libraries. I think it is a very strong way to encrypt, specially if the text has more than 1 KB. The application reads encrypted bytes from disk, and writes encyrpted bytes to disk, so it never is saved in the hard disk decrypted. JDK-17 compatibility. You will find more about it at this web site: https://www.frojasg1.com:8443/downloads_web/web/html/encriptadorDeTexto.html?origin=sourceforge

TCPFile is a friend to friend file sharing / instant messaging Java (1.6) program offering zipped and fully encrypted (RSA, AES) communication.

A client-server multithreaded application for bruteforce cracking passwords. The more clients connected, the faster the cracking. Plugin-based. Supports only RAR passwords at the moment and only with encrypted filenames.

Allow the use of ALL smart cards (including EID or DoD smart card) to logon on Windows Vista & later on stand alone computer. This solution doesn't need an Active Directory. Please look at the projet homepage to see a list of smart cards tested.

EverCrack cryptanalysis engine. The goal is cryptanalysis of any class of cipher. The focus now is the kernel - cryptanalysis of unilateral monalpha substitution ciphers extremely quickly, and later, cryptanalysis of complex ciphers for the kernel.

A tight python crypto module implementing only the latest and greatest: Rijndael (AES) symmetric cipher in 128, 192 and 256 bits supporting password encryption, SHA 256 and several CSPRNG schemes in pure python.

File Crypter is a Simple program, that is able to encrypt your files and decrypt them. A version of File Crypter is included as an example in the xCrypter Library and is called "ncrypter" which is short for "new crypter".

JHide is simple steganography tool aimed to demonstrate basic steganography techniques.

Yet another Windows password manager, easy to learn and easy to use, no categorization, strong Blowfish encryption. There is no installation, just a single executable in a small package, no mess with the windows system registry.

It is a pure qt version of gtk-based cryptkeeper. It allows to create encrypted folders, mount them and import folders created by encFS utility. Program resides in system tray.

A software written in java to compute the digital signature on documents and verify them, using a smart card or a token file in p12 format

yaSSL, or yet another SSL, is an embedded ssl library for programmers building security functionality into their applications and devices. yaSSL is highly portable, and runs on standard as well as embedded platforms(QNX, ThreadX, VxWorks, Tron) yaSSL is still available but no longer being developed. Current development on the same project continues under wolfSSL. Visit yaSSL Home above for the latest stable release.

Small stream encryption program for Unix

Barreto & Rijmen 128-bit block cipher with GCM Mode (RFC 5288) provides both authenticated encryption (confidentiality and authentication) and the ability to check the integrity and authentication of additional authenticated data (AAD) that is sent in the clear. Whirlpool-based PBKDF2. Anubis is a block cipher with SP-network structure designed by Vincent Rijmen and Paulo S. L. M. Barreto in 2000. This project is licensed under the ISC License.

Any comments or question should be directed to the Discussion section of this website. I'll respond to any post directed there. Still in alpha stage. We take a file/stream and break it down to 8bit ASCII "0-255" values. We then take those values and combine with individual 8bit ASCII values of the password/pass phrase. We loop thru the file combining 1 byte with 1 byte from "password phrase" in a continuous loop. We then write all odd results then even results to a file, array or string "your choice". I'm not a mathematician "not even sure what they are" but I think the results equal n exp 256 + n exp 256 + n exp 256 * n exp 2,147,483,647. Again, not a mathematician. This project was written using VS 2019 Community Edition. C# .NET Framework 4.7.2 I have included a sample program or change the source to fit your needs. I'm working on documenting the class so you can easily make changes as needed.

DrCrypt, based on basic xor(exclusive or) encryption which is designed to be fast and reliable. Also DrCrypt supports 3 platform.(Java, .NET, Win32)

This tool can create one-time-password values based on HOTP (RFC 4226: HOTP: An HMAC-Based One-Time Password Algorithm), TOTP (RFC 6238: TOTP: Time-Based One-Time Password Algorithm) and OCRA (RFC 6287: OCRA: OATH Challenge-Response Algorithm) standards, and also supports client side of OAuth protocols (1.0a, 2.0).

The PKI Framework (PKIF) is a cross-platform library for performing PKIX-compliant certificate processing. It includes support for SCVP, OCSP, CMS and Timestamps. It uses Windows CAPI, NSS or Crypto++ for cryptographic services and hardware support.

Encryption/Decryption demonstration app using the S-DES algorithm. Use the Java runtime environment 11 for execution. The GUI pops up that allows entering a 10-bit encryption/decryption key in binary (0, 1 digits) and the plaintext/ciphertext in the same form (8-bit). Executing the algorithm, decription of the encoding/decoding functionality is provided in the three main text boxes.

This is a tool that uses a combination between a brute force and dictionary attack on a Vigenere cipher. At present, keys are generated using brute force (will soon try passwords generated from a dictionary first). Each key is then used to decode the encoded message input. The output is analysed and then put into a ranking table. Outputs will be ranked on a variety of factors (at present, only number of dictionary words in output are counted). For the future: Better key generation, trying combinations of dictionary words with numbers. If that fails, brute force will be used. For all attempts of the dictionary attack, only keys within the known key length range will be generated. Better ranking system and analysis of possible decoded messages. Note: The version currently released, I made in an evening! It is nowhere near ready for release but is a fun project to think about and I need more ideas for improvements mentioned above. Discuss possible solutions and ideas!

crax is a wordlist based md5/sha1 tester, written in c++ for Linux and other *nix based systems.

Python wrapper around a small subset of the OpenSSL library. Includes: X509 Certificates, SSL Context objects, SSL Connection objects using Python sockets as transport layer. The Connection object wraps all the socket methods and can therefore be use

sha is a file hashing utility that uses the NIST's SHA-1, SHA-256, SHA-384, & SHA-512 hash algorithms. It can be used for file integrity checking, remote file comparisons, etc. The portable algorithm implementations can be useful in other projects too.
