I am unable to use encryption when the output is STDOUT

[Konstantinusz]

I have tried the following command:
echo $'123\n123'|lrzip -o - -e file.txt|pv > archive.lrz

I get an error message:

Read of length 25 failed - Bad file descriptor                                                                                                        
Failed to read_buf buf in rewrite_encrypted

1, echoing a password is very insecure
2. the -o option is not for special files
3. if you must, use -o archive.lrz
4. -e can't be used with STDIN for input files and if you output using > won't prompt for a password.
5. use this: echo $'123\n123'|lrzip -o archive.lrz -e file.txt and add -vv for greater verbosity, not pv
6. The bad file descriptor error is due to the fact that -o - is not a real file and lrzip is trying to seek to a position in the file to begin writing the stream data header. Probably could be checked for on program init, i.e. -o - is illegal, but IMO not worth the time.
7. don't echo passwords.

Encryption is not possible with any stdio. Fixed with appropriate warning in git master.
