= LEX (cipher)
{wiki=LEX_(cipher)}
LEX (short for "Lexicographical") is a type of block cipher that is designed to operate on fixed-size blocks of data. The exact specifications can vary, but generally, it is meant for secure encryption and decryption of data. The term "lexicographical" implies that the cipher may involve some ordering principles akin to those in dictionary sorting.
