Encpipe
=======
The dum^H^H^Hsimplest encryption tool in the world.
# Usage
Encrypt a file using a password:
```sh
encpipe -e -p password -i inputfile -o outputfile
```
Decrypt a file using a password:
```sh
encpipe -d -p password -i inputfile -o outputfile
```
`-i` and `-o` can be set to `-` or omitted to read/write from the
standard input/output.
Example - encrypted file transfer:
```sh
nc -l 6666 | encpipe -d -p password
encpipe -e -p password -i /etc/passwd | nc 127.0.0.1 6666
```
Example - compressed, encrypted archives:
```sh
zstd -5 -v -c "$FILE" | encpipe -e -p "$PASSWD" -o "${FILE}.zstd.encpipe"
```
# Dependencies
None. It includes [libhydrogen](https://github.com/jedisct1/libhydrogen) as
a submodule. There is nothing to install.
# Installation
```sh
make
sudo make install
```
[Precompiled, static binaries for Linux](https://github.com/jedisct1/encpipe/releases/latest) are also available.
Use `gmake` instead of `make` on BSD systems.
# Why
It was faster to write than remember how to use GnuPG and OpenSSL.
# Yes
It's using passwords. Provided on the command-line. Yes, it actually
does that. I needed that. Right now. Other options will be
implemented. Next year.
