thanks @user4982, very useful information.

comment Do we have to use an IV for AES encryption to be FIPS 140-2 compliant?
thanks. Yes, we are using all zero IVs with CBC mode. Question about your point "It was discussed above that it may not be recommendable to use all zeroes for CBC", if we are using different key for encryption of different file with CBC mode, based on some above comment (@fgrieu and @Stephen Touset), it should not be an issue, right? Or am I missing something.

thanks @fgrieu. To be more clear, for each file, we are using a different key generated dynamically from a random salt.

thanks @StephenTouset. we are not independently encrypting multiple blocks of same file, rather we are using CCryptorCreate to create a cryptor and then use CCryptorUpdate to update the crpytor with more data (32 K bytes every update). Here is the API: developer.apple.com/library/ios/documentation/System/Conceptual/…
