Hello All,

So here is the challenge, i have to integrate with a partner who has shared the working example on: http://aes.online-domain-tools.com/

Input text - set as HEX:

3132333435363738393031323334353632373832343634303031305468697320697320612074657374206D657373616765FFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

Function: AES

Mode: CBC

Key set as HEX: 01F0E0D0C0B0A090807060504030201001F0E0D0C0B0A0908070605040302010

IV: 8006e3b6dbdb4865e079d0543c6007bc

Certain values changed for obvious reasons.

Challenge :

 my $cipher = Crypt::CBC->new(
    -cipher => 'Crypt::Cipher::AES',
    -key       => $key,
    -iv       => $iv,
    -padding => 'none',
    -header => 'none',  
    -keylength => '256' ,
    -literal_key => 1
    );

This is naturally failing due to IV size (not sure if it is related to hex values, etc. Any insight as to how to solve?

Thanks
