  2. Ransomware - Wikipedia

    en.wikipedia.org/wiki/Ransomware

    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.

    Remaining existing US software have disabled the decrypt / unencrypted / de-lock feature that allows bypass the Blu-ray disc protections. As from October, 2014 MakeMKV, MyBD and AnyDVD (AnyDVD is like a driver for decrypt purposes only) are able to decrypt Blu-ray disc protection as being are freeware applications.

    en.wikipedia.org/wiki/REvil

    REvil (Ransomware Evil; also known as Sodinokibi) was a Russia-based [1] or Russian-speaking [2] private ransomware-as-a-service (RaaS) operation. [3] After an attack, REvil would threaten to publish the information on their page Happy Blog unless the ransom was received.

  5. GOST (block cipher) - Wikipedia

    en.wikipedia.org/wiki/GOST_(block_cipher)

    GOST has a 64-bit block size and a key length of 256 bits. Its S-boxes can be secret, and they contain about 354 (log 2 (16! 8)) bits of secret information, so the effective key size can be increased to 610 bits; however, a chosen-key attack can recover the contents of the S-boxes in approximately 2 32 encryptions.

  6. VeraCrypt - Wikipedia

    en.wikipedia.org/wiki/VeraCrypt

    It generates the header key and the secondary header key (XTS mode) using PBKDF2 with a 512-bit salt. By default they go through 200,000 to 500,000 iterations, depending on the underlying hash function used and whether it is system or non-system encryption. [14] The user can customize it to start as low as 2,048 and 16,000 respectively. [14]

  7. GOST (hash function) - Wikipedia

    en.wikipedia.org/wiki/GOST_(hash_function)

    GOST processes a variable-length message into a fixed-length output of 256 bits. The input message is broken up into chunks of 256-bit blocks (eight 32-bit little endian integers); the message is padded by appending as many zeros to it as are required to bring the length of the message up to 256 bits. The remaining bits are filled up with a 256 ...

  9. Advanced Access Content System - Wikipedia

    en.wikipedia.org/wiki/Advanced_Access_Content_System

    AACS uses cryptography to control and restrict the use of digital media. It encrypts content under one or more title keys using the Advanced Encryption Standard (AES). Title keys are decrypted using a combination of a media key (encoded in a Media Key Block) and the Volume ID of the media (e.g., a physical serial number embedded on a pre-recorded disc).
