It's impossible to say without the encryption code. Fairly sure this padding is
added while encrypting.
If I could trouble you again dissolved_girl I think what we spoke about above
is what is causing me trouble today. I have started writing out the Non
Encrypted Raw file then adding the Decrypted Raw data underneath and I can see
after 16 entries the data is padded out with 16 entries of 16 then
Thank you, understood now.
That's PKCS padding. It's literally just the number of bytes of padding (in
hex) repeated until the end of the block.
Thank you that worked a treat and I appreciate I will definitely need to
improve my best practices with this code. Just dipping my toe in at the moment.
One thing I noticed is that it seems to be padded with extra characters
compared to what I think it should be in HEX and a String output. Any i
Thanks jtv, that is really useful code and very much appreciated. Definitely
going to incorporate that into my future projects.
One catch for me is the tool I am using only spits out AES CBC 128 given it is
only worried about some minor obsfucation so I still need to somehow crack my
issue. If
Regarding your code, your problem is that your input is hex-encoded, but you
decode it as bytes.
A simple fix would be replacing this line:
let cryptedInput = toByteSeq(encryptedInput)
... with this:
let cryptedInput = cast[seq[byte]](parseHexStr(encryptedInput))
and
BTW, I see you're on windows; I only develop for Posix systems, and def don't
test on wsl2, but OpenSSL should be there on windows. All you need from it are
aes.nim and random.nim which are built only on OpenSSL, so you should be able
to yank those two files out.
I also used `strDump()` and
First, you should never be using CBC mode for a number of reasons, including no
tamper detection, and potential issues with padding attacks, such as ones that
have hit TLS in the past.
Instead, you should be using a more modern encryption mode that does integrity
checking by default.

Hi all,
I have only recently started working with NIM and I am loving it but I have hit
a little stumbling block. I am trying to get some simple AES encryption working
and for the life of me I can't seem to be able to do it. I have no doubt some
AES experts on here will spot my mistake instantl
