 CBC, OFB, CFB, PCBC, GCM mode require an initialization vector (IV) as an initial input to the cipher. The IV doesn't have to be kept secret, but it shouldn't be predictable: it should be random and unique/non-repeatable for each encrypted message. Make sure that IVs are generated using a cryptographically secure random number generator. For more information on IVs, see [Crypto Fail's initialization vectors article](http://www.cryptofails.com/post/70059609995/crypto-noobs-1-initialization-vectors "Crypto Noobs #1: Initialization Vectors").
 
-Pay attention on cryptographic libraries used in code: many open source libraries provide examples in documentations that follow bad practices (i.e. using a hardcoded IV). A popular mistake is copy-pasting example code without changing IV value.
