The development of CrypTool started in 1998. Originally developed by German companies and universities, it is an open-source project since 2001. [2]Currently 4 versions of CrypTool are maintained and developed: The CrypTool 1 (CT1) software is available in 6 languages (English, German, Polish, Spanish, Serbian, and French).
In cryptography, a message authentication code (MAC), sometimes known as an authentication tag, is a short piece of information used for authenticating and integrity-checking a message.
The MixColumns operation performed by the Rijndael cipher or Advanced Encryption Standard is, along with the ShiftRows step, its primary source of diffusion.. Each column of bytes is treated as a four-term polynomial () = + + +, each byte representing an element in the Galois field ().
A number of modes of operation have been designed to combine secrecy and authentication in a single cryptographic primitive. Examples of such modes are , [12] integrity-aware cipher block chaining (IACBC) [clarification needed], integrity-aware parallelizable mode (IAPM), [13] OCB, EAX, CWC, CCM, and GCM.
In cryptography, a Feistel cipher (also known as Luby–Rackoff block cipher) is a symmetric structure used in the construction of block ciphers, named after the German-born physicist and cryptographer Horst Feistel, who did pioneering research while working for IBM; it is also commonly known as a Feistel network.
In cryptography, a padding oracle attack is an attack which uses the padding validation of a cryptographic message to decrypt the ciphertext. In cryptography, variable-length plaintext messages often have to be padded (expanded) to be compatible with the underlying cryptographic primitive.
xx messenger uses cMix - a network of decentralized servers called xx network that are run by independent operators in approximately 80 countries - for data transmission. [8] cMix attempts to address traditional latency and scalability limitations of mix networks by performing computationally expensive public-key operations between mix nodes prior to any client data being transmitted over the ...
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.
