aesutil是一个小型的库和命令行程序

This is a small library and a command line program to encrypt/decrypt 
data using the Rijndael encryption algorythm in cbc mode.

The Utility should run at least under Linux, Mac OS X and Windows. Other Unices
have not been tested, reports are welcome.

Most of the code is taken from Brian Gladman's windows implementation
that can be found at

http://fp.gladman.plus.com/cryptography_technology/rijndael/index.htm

Markus Lagler added a wrapper library to encode/decode from/to memory
instead of files.

Tim Tassonis did some minor UNIX porting stuff and added the command
line program.

The getopts ist taken from Steve Merz:

Usage of the command line program:

Usage: ./aes [options]

  --help,       -h                      Displays this information
  --encrypt,    -e                      Encrypt the data
  --decrypt,    -d                      Decrypt the data
  --base64,     -b                      base64 encode/decode encrypted data
  --password,   -p <args>               Password (if omitted, will prompt)
  --string,     -s <args>               Input String (if omitted, stdin)
  --file,       -f <args>               Input File (if ommitted, stdin)
  --count,      -c <args>               Number of input bytes to read
  --out         -o <args>               Outputfile instead of stdout

Either -d or -e always has to be specified, there is no default

With -e, -b will encode the resulting data in base64, when used with -d
it will treat the input as base64 encoded.
