Information
The Advanced Encryption Standard (AES) is a U.S. Federal Information Processing Standard (FIPS). It was selected after a 5-year process where 15 competing designs were evaluated.
How to use:
Firstly, input a key. This will be used in the algorithm to encrypt your plaintext. Alternatively, the generate key button will do so for you.
Then, input some plaintext; what you want to encrypt. An output will appear in the bottom boxes with the base64 and hexadecimal versions of your ciphertext along with execution time.
Conversely, to decrypt, simply add the base64 ciphertext into the top input box along with key to decrypt with.
