Abstract
Techniques for using padding in format preserving encryption are provided. In one aspect, it may be determined if padding of a plaintext undergoing format preserving encryption is needed. A pseudo random padding length may be calculated when it is determined that padding is needed. The calculated length of padding may be added to the plaintext when it is determined that padding is needed. The plaintext and added padding may be encrypted using format preserving encryption to create a cipher text.
