# This is a pure-Python implementation of the AES algorithm and AES common
# modes of operation.

# See: https://en.wikipedia.org/wiki/Advanced_Encryption_Standard
# See: https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation


# Supported key sizes:
#   128-bit
#   192-bit
#   256-bit


# Supported modes of operation:
#   ECB - Electronic Codebook
#   CBC - Cipher-Block Chaining
#   CFB - Cipher Feedback
#   OFB - Output Feedback
#   CTR - Counter

# See the README.md for API details and general information.
