DeepSound – Audio Steganography Tool

DeepSound is an audio steganography tool and audio converter that hides secret data into audio files, the application also enables you to extract secret files directly from audio files or audio CD tracks.

This audio steganography tool can be used as copyright marking software for wave, flac, wma, ape, and audio CD.
DeepSound also support encrypting secret files using AES-256(Advanced Encryption Standard) to improve data protection. The application additionally contains an easy to use Audio Converter Module that can encode several audio formats (FLAC, MP3, WMA, WAV, APE) to others (FLAC, MP3, WAV, APE).

VSHG – Hardware resistance & enhanced security for GnuPG

VSHG aims to provide a memory / hardware resistant reinforcement to GnuPG’s standared s2k key-derivation-function + a simplified interface for symmetric encryption .About VSHGVSHG ( Very secure hash generator ) is a standalone Addon for GnuPG ( Gnu privacy guard ) . It is written as a shell script and is designed around the Unix/Linux filesystem and commands. VSHG uses the sha384 and the Argon2 hash function for the password and AES-256-CFB + CAST5-128-CFB in cascade for the final encryption.And also a standard sha384 iteration count of 800 iterations + 15 & 500 iterations for Argon2i + dIt uses True random 12 byte salts . So even if your passphrase is very weak , it will reinforce it so that you don’t have to worry about that anymore.VSHG uses the last hash of the Iteration as session key for Gnupg. It also provides an Autodetection function for each file so that you don’t have to remember either the salt or the iteration count.Optionally you can use a key-file as authentication method.Why is VSHG so secure ?VSHG uses a true random salt for each encrypted file, so your Passphrase will always have a minimum of 12 bytes in strength. You could even use the same password twice for different files. The thing that makes VSHG so secure are the iterations. 800 iterations mean the output of the string is hashed 800x with its output. The more iterations the more security there will be. Even if you have the correct passphrase, but not the correct amount of iterations it will not be able to decrypt.VSHG uses some of the most advanced forms of memory hard Key derivation functions which are Argon2i and Argon2d. The already iterated key will be passed through Argon2 a total of 515 times and therefore ensure the resistance against the biggest threats of Key derivation functions Namely: Graphical Processing Units, Field programmable gate arrays and Application specific integrated circuits ( GPU , FPEGA , ASIC ) .The actual encryption is performed with the highest level of security possible in Gnupg.-The string to key ( s2k ) hash algo ( which is the KDF of Gnupg ) was reinforced from sha1 to sha512.-The s2k mode was set to 3 which means that an 8-bit salt is applied and then iterated.-The s2k count was set to 65011712 which is the highest possible number of iterations.-The s2k algo was set to AES256 and CAST5 in cascade.The AES 256 encrypted file is securely deleted so that only the AES256(Cast5()) encrypted file is put out.Why should I use VSHG ?It is easier to use than GnuPG core.Can encrypt folders by turning them into Zip files.Someone that doesn´t have VSHG does not really have a chance of cracking the password.True random 12 byte saltchoosable Iteration count.choosable Salt.choosable Keyfile.True random Keyfile.Very good resistance to side channel attacks ( e.g: timing attacks ).Very resistant towards GPU based attacksCan guarantee security even with relatively weak passwords ( > 5 characters ) ( if you have enough Iterations )Autodetection of Salt + Iteration count for each file.Military standard AES-256 encryption + the gpg standard CAST5 encryption.Uses the gpg s2k mode 3 + sha512 with the maximum count of 65011712.Erases Original file securely.Download & InstallationDownload as tarballsudo wget https://github.com/RichardRMatthews/VSHG/archive/1.4.tar.gzOr clone the repositorygit clone https://github.com/RichardRMatthews/VSHG.gitCompile it yourselfsudo git clone https://github.com/neurobin/shc.gitcd shcsudo ./shc -f -r /etc/VSHG/executable/src/VSHG_1.4.shsudo gcc /etc/VSHG/executable/src/VSHG_1.4.sh.x.c -O /usr/bin/VSHGsudo VSHGRunsudo tar -xf VSHG-1.4.tar.gzsudo chmod +x VSHG_1.4.shsudo ./VSHG_1.4.shDownload VSHG

Imperva Makes Major Expansion in Application Security

When Imperva announced in 2018 it would acquire the application security solution provider Prevoty, a company I co-founded with Julien Bellanger, I knew it would be a win-win for our industry. Prevoty’s flagship product, Autonomous Application Protection, is the most mature, market-tested runtime application self-protection (RASP) solution (as proof, Prevoty was just named a Silver […]
