    CrococryptFile

    CrococryptFile

    An encryption tool for creating file archives

    CrococryptFile is a file encryption tool which creates encrypted archives of files and folders. The encryption features of CrococryptFile can be compared to a ZIP utility that uses ZIP's AES encryption. However, there are significant differences. CrococryptFile... - encrypts all file and folder information including filenames, time/date and filesize information, - disguises any information of the archive's content, because all data and meta-data is simply integrated into a giant file dump. =Crypto Suites= For a full list of and details about supported crypto suites, please visit the CrococryptFile Homepage. Examples: - Password-based encryption (following PBKDF2) with AES-256, Twofish, Serpent, ... - Public key encryption using GPG/OpenPGP, Windows Keystore/CAPI with RSA/X.509 certificates - Cloaked (headerless) Password-based Encryption (AES-Twofish-256 cascaded) - ...

    Naeon

    Naeon

    The safest way to store private data in untrusted (cloud) environments

    Naeon is a data encryption and sharding method designed to secure data in potentially untrusted off-site storage locations. It uses AES-256 encryption with a randomly generated passphrase, followed by obfuscation techniques to make the encrypted file unidentifiable. The data is then sharded into one private chunk containing the encryption key and part of the data, and multiple public chunks. Each chunk is renamed using its SHA-512 hash, and all chunks are timestamped equally. A filename conversion table is created to restore the concatenation order during a restore. The method aims to guarantee confidentiality, integrity, and availability of data, regardless of the trustworthiness of the chosen storage environment, while protecting against data breaches and unauthorized access. Threshold Key Sharing further enhances security and resilience by splitting the private key into parts requiring cooperation from multiple parties for reconstruction, thereby minimizing single points of failure.

    cross-platform (Java) file encryption and archiving tool

    Java based API (library) and console utility for cross-platform file and directory encryption and archiving. Encrypts single files up to 9.2 EB length. Directories can be encrypted as sets of single files in a single action. Uses Twofish (CBC) and SHA-256. Security level is strong and benefits from the PWS3 (Password Safe) encrypted file format. The level can be lowered to 128-bit key-length (normally 256).

    HashApp

    python software for cracking and creating SHA and MD5 hashes

    A python software that can be used for encrypting text in SHA384, SHA512, SHA224, SHA1, SHA256 and MD5; or for cracking six different types of hashes, namely SHA384, SHA512, SHA224, SHA1, SHA256 and MD5 through a dictionary attack using an online txt file. You need to have python 3 or above installed to run this progam. If you would like to change the online dictionary URL for hash decryption, use CTRL+F in your text editor and search for this line: LIST_OF_WORDS = str(urlopen('https://raw.githubusercontent.com/dwyl/english-words/master/words.txt').read(), 'utf-8') Change the url in the urlopen function and replace all instances with your version of the above line. If you want to use a txt dictionary stored in your computer, then, well, nothing. Unless the word search fails with the online dictionary, you can't use a txt dictionary. But don't worry; you just have to store your txt on github (like the default dictionary above).
