Examples of encrypting Encrypt a file and store the output to a new file and specifying the password as a parameter:

encdec -e -p guesswhat -i c:\bigsecret.txt -o c:\bigsecret.enc
Decrypt a file and store the output to a new file, without specifying the password as a parameter, encdec will ask you to enter the password:
encdec -d -i c:\bigsecret.enc -o c:\bigsecret.txt
Encrypt a file and store the output in the same file:
encdec -e -ow -i c:\bigsecret.txt -o c:\bigsecret.txt
Decrypt a file and store the output in the same file:
encdec -d -ow -i c:\bigsecret.txt -o c:\bigsecret.txt
