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.

The Yandex search takes into account the morphology of the Russian language, therefore, regardless of the form of the word in the search query, the search will be performed for all word forms. If morphological analysis is undesirable, you can put an exclamation mark (!) Before the word — the search in this case will show only the specific ...
A word search, word find, word seek, word sleuth or mystery word puzzle is a word game that consists of the letters of words placed in a grid, which usually has a rectangular or square shape. The objective of this puzzle is to find and mark all the words hidden inside the box.
The encryption process consists of updating the state with four round functions over 10 rounds. The four round functions are SubBytes (SB), ShiftColumns (SC), MixRows (MR) and AddRoundKey (AK). During each round the new state is computed as S = A K ∘ M R ∘ S C ∘ S B ( S ) {\displaystyle S=AK\circ MR\circ SC\circ SB(S)} .
All algorithms support authenticated encryption with plaintext P and additional authenticated data A (that remains unencrypted). The encryption input also includes a public nonce N, the output - authentication tag T, size of the ciphertext C is the same as that of P. The decryption uses N, A, C, and T as inputs and produces either P or signals ...
WAKE is noted for its speed, making it suitable for applications requiring fast encryption. However, it has been found to be vulnerable to both chosen plaintext and chosen ciphertext attacks. These vulnerabilities arise from the cipher's reliance on previous ciphertext blocks for keystream generation, which can be exploited in certain attack ...
