AES is NIST-certified and is used by the US government for protecting "secure” data, which has led to a more general adoption of AES as the standard symmetric key cipher of choice by just about everyone. hämärästä aamunkoittoon 2 texas blood money 1999 rooleissaWebAug 26, 2016 · With AES-CBC you usually need a random IV. However, in the case where you use each key only once, like when using password-based encryption with random salts for each file, you can use a fixed, zero IV. So as long as you use a new salt for each file – and even new versions of the same file – you can forgo storing an IV and just use a zero block. hämärästä aamunkoittoon 2 texas blood money 1999
