First, choose the range that you want to encode:

• By default, the entire line is encoded.
• If you want to encode a specific string, use -s.
• If you want to encode the part that matches a regular expression, use -r.

Second, choose the type of encoder you wish to run via -e. The encoder can consist of multiple chains.

# Encoder chanins
# You can use '>' and '|' and ',' characters for chain.
-e "base64"
-e "base64>md5"
-e "url|upcase|md5"
-e "url>upcase,md5"
