PCSecrets is a PC application that holds secret text data - protected by a master password and strong encryption. Use it as a password manager or just somewhere to hold any text data securely in one place. It can hold a second, hidden set of secrets that is undetectable and plausibly deniable. The program is also a PC counterpart of the Secrets for Android app. It uses the same data structure and provides synchronization that allows easy transfer of secrets between the two. For those who find the personal computer environment more comfortable for data entry and editing (i.e. a real keyboard), PCSecrets provides an alternative way to manage your secrets. Sync is also effectively a form of backup. To enable the sync feature with Secrets for Android, you need to install the PCSecrets Sync app, downloadable from SourceForge or Google Play. PCSecrets import plus PCSecrets Sync provides a route to importing secret data into Secrets for Android that would not otherwise be possible.

Java based Portable hashing application capable of multiple individual file signatures or proprietary group signatures (1 signature for a folder and all its contents). GUI and command line in the same executable. -sha1 -sha256 -sha51 -md5 -crc32

A text editor which saves data encrypted with strong cryptography (AES, Blowfish..)

Pure managed C# implementation of well-known cryptographic hash functions such as SHA-family (SHA0, SHA1, SHA2), MD-family (MD2, MD4, MD5), RIPEMD, Tiger, Haval, Snefru and others. Moved to Github: https://github.com/AndreyRusyaev/acryptohashnet

A package of Rijndael, Twofish and Serpent encryption algorithms implemented in x86 assembly. Meant to learn basics of assembly, learn about the algorithms or to be used in a C program.

AUM is an extremely fast, small-state, cryptographically secure pseudo-random number generator and stream cipher. AUM exhibits uniform distribution, mixes rapidly, has no detected bias, and comes in three variants: AUM16, with an internal state array of 16+4 32-bit words; AUM32, with an internal state of 32+4 words; and AUM64 with a 64+4-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

The Ada Cryptographic Framework (ACF) is a set of Ada packages that implement the most popular cryptographic algorithms. The main goal of the proyect is to implement a complete set of cryptographic primitives entirely in Ada 95

AleHu is an open source encrypted message transfer system that encompasses both server (PHP) and client software (Java). Give it a shot: You can try out AleHu by simply running the client using the preconfigured AleHu test server! For further details and instructions on how to quickly install and run AleHu, have a look at the documentation in the Wiki section.

Encryption plugin for Alfresco. Enables the user to crypt and decrypt (it handles the 'pkcs5' MIME-type). This is a component of the IDX-eDOC project (OpenTrust suite), contributed by IDEALX

The Algebraic Toy Cipher is a toy cipher for algebraic research. It is scalable in the number of bits and in the number of rounds. Works over two fields GF(2)/P, being one for the s-box invertion and the other for the mixing layer linear transformation.

Ampare Hide Link is a script which auto hide link on your website to prevent user from knowing the final destination. Ampare Hide Link is using Defat Technology and other to protect your link on iframe and other tags. If you want to share some content but want to keep the url private. You can use Ampare Hide Link . It is free

Ano (Anonymous Network Overlay) is a decentralized IP router based on relaying principle. In Ano all IP traffic is anonymized, including TCP, UDP, ICMP and DNS protocols. Each node acts as a relay and NAT for external traffic.

AresCode2008 is system to crypt files. System is used new cryptography algorithm.

BEDBUG is a small, fast, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It exhibits uniform distribution, mixes rapidly (with worst-case avalanche better than 16-bits), has no detected bias, and comes in three variants: BEDBUG128, with an internal state array of 128+3 32-bit words; BEDBUG256, with an internal state of 256+3 words; and BEDBUG512 with a 512+3-word state. The former permit seeding with a key of up to 4096 or 8192 bits, the latter with a 16384-bit key. The BEDBUG generator itself is a mere 5 lines of code: Three rotations; two pseudo-random lookups. The default BEDBUG configuration alternates the rotation constants unpredictably. These four sets of three values differ between BEDBUG128, BEDBUG256 and BEDBUG512 and were selected, tuned and tested in each case for optimal avalanche, which is never less than 16.5 bits. BEDBUG has passed stringent industry-standard tests for randomness, including NIST and DIEHARD.

Backup P2P is a peer to peer application doing automated and secured backups inside a community (Jabber, XMPP). Each user shares some available space on his disk with others, to be able in return to remotely backup some of his own data.

BarTex is a system designed to create inexpensive tickets for events. It uses a crypto system to verify tickets using barcodes; thus eliminating the cost of expensive, colorful tickets that cannot be photocopied/forged.

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

BitShade is a graphic utility to encrypt/decrypt with AES, base64 encode/decode, calculate the SHA checksum. It is cross platform, written in Java.

Black Hole is a GPG frontend. The GUI has is file browser where you can drag and drop your files for being encrypted.

Blocked based Multi Identity Cryptographic Storage (BMICS) is a storage method that stores encrypted data of multiple users within a BMICS file without giving away details of the users in an explicit manner unless decrypted with the correct key.

Portable, optimised implementation of Bruce Schneier's 64-bit symmetric block cipher, Blowfish. Includes support for ECB, CBC, CFB, OFB and CTR block cipher modes, weak key detection and parallelisation using OpenMP.

BlowfishVHDL - free fully synthesizable Blowfish encryption algorithm hardware implementation.

A 100% pure Java Swing ASN.1 analysis utility for inspecting arbitrary BER-encoded data files. It allows inspection of data with unknown structure, can drill down to any nesting level and allows to interpret embedded OCTET STRING data recursively.

Bork is a very small, cross-platform file encryption utility. It is written in Java and designed to be included along with the files it encrypts for long-term storage (eg on CD-R). Its minimal external dependencies make it fairly futureproof.
