AES - Rijndael implementation in (Free)Pascal

Zip archive (Unix text files) containing: In October 2000, the National Institute of Standards and Technology (NIST) proposed Rijndael as the new Advanced Encryption Standard (AES), the successor of the Data Encryption Standard (DES) adopted in 1977 and Triple DES (standardized in 1999). Also see NIST's Cryptographic Toolkit. On November 28, 2001, the Federal Information Processing Standard (FIPS-197) for the AES was approved.

A slightly different version of the software in this archive played a central role in task DOUBLE on the second competition day of the International Olympiad in Informatics (IOI) held in Tampere, Finland, in July 2001. At IOI 2001, FreePascal was one of the programming tools available to the competitors.
