Can I use 256-bits IV ? Browse other questions tagged aes initialisation-vector or ask your own question. The block size of AES is always 128 bits, so a 256 bit IV is not possible for most modes of operation. I started with a fresh v2.5.7 tarball on a Solaris 8 machine.

The issue with IVs is more what/how you generate your IVs. Please don't fill out this field. Some other languages/runtimes simply ignore the IV for ECB Now there is one cipher that does allow you to specify a 256 bit IV (or actually: nonce) and that is GCM. Instead, generate a random IV and store it as the first block of your file. (This is only 16 byte overhead.) –PaĆ­lo Ebermann Aug 24 '11 at 0:22 Thanks

Any suggestions for a new writer?

To Encrypt: Initialize the Cipher for Encryption * 4. GCM converts data - includes the nonce - to a 128 bit counter for CTR mode internally. To further confuse things, some software frameworks got it wrong; e.g. Some libraries support Rijndael with 256 bit blocks, but then you're no longer using AES.
