Don't know about FIPS, but this one should do it:

Hi,
I'm using the fips approved OpenSSL to do AES encryption in ISDN, therefore,
I need to use the fips_128_AES_OFB function.
If I understand correctly this function works on a 128bit (16 byte) block,
so if I want to use it on larger blocks I need to call it in a loop.
This is different from the A
