encrypt

chi_tool -e -p password inputfile -o outputfile
chi_tool -e -p password - -o outputfile # read from stdin
chi_tool -e -p password -o outputfile # also read from stdin

decrypt

chi_tool -d -p password inputfile -o outputfile
chi_tool -p password inputfile -o outputfile
chi_tool inputfile -o outputfile  # prompt for password
chi_tool -p password inputfile -o -  # stdout
chi_tool -p password inputfile  # also stdout
chi_tool -P password_file inputfile -o outputfile

If OS environment variable CHI_PASSWORD set use that as password instead of prompting.

If password keychain available use that instead of prompt. - #6
