    Largest Generic Hash and HMAC Program

    57 Hash Functions In One Program, plus each with HMAC or KMAC

    FEHASHMAC is the largest collection of publicly known hash algorithms integrated into a command-line utility. FEHASHMAC contains a set of known test vectors and results for each algorithm such that the correct implementation for each hardware platform and compiler version can directly be verified. Currently 57 hash algorithms like sha1 sha224 sha256 sha384 sha512 and variants, sha3 and shake, all SHA3 finalists and blake3, md2 md4 md5 md6, rmd128 rmd160 rmd256 rmd320, whirl gost lash160...

    rtl2832-entropyd

    Use an rtl2832 USB dongle to generate random data for the linux kernel

    rtl2832_entropyd is a program that is designed to feed entropy into the linux /dev/random kernel entropy pool. It automatically forks and runs as a daemon, unless one of the testing options, -o or -t, are selected. Then it never forks. To use it, you need an rtl2832 USB dongle. They are relatively cheap (< $10 on ebay), and are actually used to listen to a broad range of radio transmissions. This application exploits the radio noise in the atmosphere to extract entropy. The kernel...

    sha3sum and then some

    sha3sum - A demonstration of the Keccak permutation.

    Hash mode interface to the Keccak code package. This program illustrates the use of the Keccak permutation. Usage is much more than a hash function. The NIST compatible settings are subject to change when they publish FIPS PUB 180-5. I wrote this program when evaluating the permutation and developing tree hashing for the Intel(R) MIC architecture.

    Kypeless

    Kypeless

    Fully decentralised secure p2p communication program

    Kypeless encapsulates strong symmetric and asymmetric cryptography so you can get the benefits of secure communication following some simple steps. Right now, Kypeless is unstable pre-alpha software, published only for testing purposes. Kypeless allows you to exchange instant messages, long not-so-instant messages and files, but a lot more features are planned to be implemented later.

    MOTE CSPRNG & Stream Cipher

    MOTE CSPRNG & Stream Cipher

    A family of small-state CSPRNGs and Stream Ciphers

    MOTE is a fast, small-state, cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. MOTE exhibits uniform distribution, mixes extremely rapidly, has no detected bias, and comes in three variants: MOTE8, with an internal state array of 8+4 32-bit words; MOTE16, with an internal state of 16+4 words; and MOTE32 with a 32+4-word state. The former permit seeding with a key of up to 256 or 512 bits, the latter with a 1024-bit key. Reduced to essentials, MOTE is only...

    SES Super-Encypherment Scrambler

    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...

    ISC - The ISAAC Stream Cipher

    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...

    Bigram Table Generator

    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...

    inKey - small encryption utility with big encryption block (> 800 000 bit). This program can protect very sensitive data, such e-mail, which has size up to 100 kilobytes, but processing speed might be too small with the bigger size of source data. ProcessingTime(data) = O(data ^ 2); USE IT ONLY TO PROTECT SMALL FILES (~ 100 Kb or a bit bigger). You can use "PaperBack" to print your 100 Kb encrypted *.iK file to A4 paper and get strong encrypted digital...

    MLCrypt

    Simple, lightweight, standalone command-line single file encryption.

    Simple, lightweight, cross-platform (Windows / Linux / ARM6 Linux), cross-arch (x32 / x64), standalone command line file encryption program. GnuPG is probably the best application for cross-platform encryption. However, its usage on Windows PCs may be inconvenient (installation administrator rights; large executable size for perhaps just a one-time file decryption, complicated command-line switches for stronger encryption). NCrypt would fulfill this task, but does not operate on 64-bit...
