Hi,
First of all thanks for the time to see my question.
I have a encrypted data that comes from Java webservice(AES256-base64Encoded) :

C5j45mSEdqfz4f4GnrwR2T25tizY5gb3JoVNtWp8DiYOW5d+qvPx/ODmQIQqNXpZ1YkIjLwu5BAjDh3QmlrC4DKwTvbSrVqxh7OJdGDQy60ebp0o1cmLBCJuqzAOh2KAZC6L9v4wkwEb9dFOPesImY15DySPeyYiuLHL7n2dHmyVUMcDUrp9TAm85daCyG5mKhaAy2SP8iNBPoUBWSIDDEM7vG5Ganxu6JVzG4V6zGYQlLXAi33Ct9Fs99YE02KKR4kiw52eE1nS4hwReMZnP4vuU1FxM0BZfWAdUV8m9pQ=
Now I also have a 32 bit key to decode it (base64Encoded):

v3erqY/EGg1NI0yFHYLsMt7IuqJksxNjo1dlhsOo6Zs=

So after decryption, I should get the following data below:

http://b2bfsta.edc.cingular.net:8180/b2bservlets/TCMLoginDispatch.dyn?loginChannel=EBM&uid=B2c18e47fbc6e94ec7e5a92dece2c2684a4e3421a&sourceSystemId=iPhone6-NewOrder&profileType=PLATINUM&peDealId=o31634600562&enableDDR=true

I know if I encrypt in Apex then I can use decrypt(String, Blob, Blob, Blob) or decryptWithManagedIV(String, Blob, Blob).
But in this case, I don't why I am getting error, I tried all options available . PLease find sample code:

--------------------------------------------------------------------------------------------------------------------------------------------------------
Blob key = EncodingUtil.base64Decode('v3erqY/EGg1NI0yFHYLsMt7IuqJksxNjo1dlhsOo6Zs=');
String encodedData ='C5j45mSEdqfz4f4GnrwR2T25tizY5gb3JoVNtWp8DiYOW5d+qvPx/ODmQIQqNXpZ1YkIjLwu5BAjDh3QmlrC4DKwTvbSrVqxh7OJdGDQy60ebp0o1cmLBCJuqzAOh2KAZC6L9v4wkwEb9dFOPesImY15DySPeyYiuLHL7n2dHmyVUMcDUrp9TAm85daCyG5mKhaAy2SP8iNBPoUBWSIDDEM7vG5Ganxu6JVzG4V6zGYQlLXAi33Ct9Fs99YE02KKR4kiw52eE1nS4hwReMZnP4vuU1FxM0BZfWAdUV8m9pQ=';
Blob exampleIv = Blob.valueOf('Example of IV123');
Blob decryptedData = Crypto.decrypt('AES256', key ,exampleIv, EncodingUtil.base64Decode(encodedData));
//Blob decryptedData = Crypto.decryptWithManagedIV('AES256', key, EncodingUtil.base64Decode(encodedData));

The problem is that the encrypted code is not getting decrypted in apex using standard way . Please help me out.

We want to be able to log an object for historical purposes but it's way too much data to do that through salesforce so I figured we could dump the data into a CSV file. I want to be able to dump the CSV file itself directly to the attachments object if that's possible. 

The way I'm currently generating the CSV file is by using the following in my visualforce page...

<apex:page standardController="Facility_Carrier_Contract__c" extensions="mc_FCCCodeHistory" id="page" standardStylesheets="false" showHeader="false" sidebar="false" contenttype="application/x-excel#export.csv">
{!exportData}</apex:page>
