i have field in database. ex: field name. this field maybe more than 16 byte. how to encrypt data more than 16 byte without cbc, etc?
any function or another ways to do this?
A function that extends your fixed-size cipher to deal with larger inputs is exactly what is called a "Mode of Operation". So any function qualifying would in essence be a "Mode of Operation". There may be solutions if you tell us exactly why a Mode of Operation doesn't work for you
