'COMPLIANCE TESTING
'
'There are many AES and Rijndael Test Vector Files available on the internet so you can
'verify that an implementation is correct. Below is a simple test that encrypts and
'decrypts one block for each of the 25 combinations of block and key size. These test
'vectors were created by Dr Brian Gladman.
'
'If the "Plaintext is hex" CheckBox is checked, plaintext is read and written as Hex values,
'just like the ciphertext. Also, you can enter a Hex value in the txtPassword TextBox.
'To use the "Plaintext is hex" CheckBox, you need to make it visible yourself. Then you
'can "cut and paste" data directly from known answer test value files.
'
'I've done a reasonable amount of compliance testing, including a few (10,000 iteration) monte
'carlo tests. I am fairly certain that the class is 100% compliant. If you find any problems
'or strange behavior, please let me know so it can be corrected.
