This page presents the following features:
* Implementation of the Rijndael cipher, which has just been selected as the
Advanced Encryption Standard
* Local operations only, no data travels access the Internet
* Simple password could be used instead of hard-to-remember 128 bit key for encryption.
* Could be used online from the web or offline as a file.
Possible usage:
* Password Management: store different access information protected by a
master password
* E-mail encryption: Encrypted e-mail could be sent with URL to this page,
so the recipient could decrypt the e-mail on a local machine
* On-line information protection: store your encrypted information on a
publicly accessible web server with ability to decrypt it from another
public computer (i.e. in an Internet cafe) using this page
Noticed risks/disadvantages:
* This is a very simple solution: consider more robust for business critical systems
* You have to trus the local computer your performing encryption/decryption and cut/paste operations
* Slow computation: the Rijndael implementation is not optimized
* May be slow to download over dial-up connection
* Key size (128 vs. 256) incompatibility with Rijndael PERL implementation
