VeraCrypt is a free and open-source utility for on-the-fly encryption (OTFE). [5] The software can create a virtual encrypted disk that works just like a regular disk but within a file.
Bullrun (stylized BULLRUN) is a clandestine, highly classified program to crack encryption of online communications and data, which is run by the United States National Security Agency (NSA). [1] [2] The British Government Communications Headquarters (GCHQ) has a similar program codenamed Edgehill.
The Encrypting File System (EFS) on Microsoft Windows is a feature introduced in version 3.0 of NTFS [1] that provides filesystem-level encryption.The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
The original creation of Gpg4win was initiated and funded by Germany's Federal Office for Information Security (BSI) in 2005, [2] [3] resulting in the release of Gpg4win 1.0.0 on 6 April 2006; [4] however Gpg4win and all included tools are free and open source software, and it is typically the non-proprietary option for privacy recommended [5] [6] to Windows users.
In cryptography, the EFF DES cracker (nicknamed "Deep Crack") is a machine built by the Electronic Frontier Foundation (EFF) in 1998, to perform a brute force search of the Data Encryption Standard (DES) cipher's key space – that is, to decrypt an encrypted message by trying every possible key.
One of the modes John can use is the dictionary attack. [6] It takes text string samples (usually from a file, called a wordlist, containing words found in a dictionary or real passwords cracked before), encrypting it in the same format as the password being examined (including both the encryption algorithm and key), and comparing the output to the encrypted string.
There are a number of tools intended specifically to decrypt files locked by ransomware, although successful recovery may not be possible. [2] [154] If the same encryption key is used for all files, decryption tools use files for which there are both uncorrupted backups and encrypted copies (a known-plaintext attack in the jargon of cryptanalysis.
The length of the encryption key is an indicator of the strength of the encryption method. [29] For example, the original encryption key, DES (Data Encryption Standard), was 56 bits, meaning it had 2^56 combination possibilities. With today's computing power, a 56-bit key is no longer secure, being vulnerable to brute force attacks. [30]
