How do I decrypt a file with mcrypt?

Question

I have the following:

• mcrypt installed
• a file with a .zip.nc extension
• a password

How do I use mcrypt to decrypt the file? The man page isn't very helpful.

I've tried

mcrypt -k password file.zip.nc > output

But nothing seems to be happening.

Answer 1

Try:

mcrypt -d file.zip.nc

You should then be prompted for your password and the file should decrypt.
