Tweetpipe
=======
A fork of the dum^H^H^Hsimplest encryption tool in the world,
[encpipe](https://github.com/jedisct1/encpipe), but with the crypto replaced by
tweetnacl. Password hashing is implemented by a custom tweet-like version of
pbkdf2hmacsha512.
# Usage
Encrypt a file using a password:
```sh
tweetpipe -e -p password -i inputfile -o outputfile
```
Decrypt a file using a password:
```sh
tweetpipe -d -p password -i inputfile -o outputfile
```
`-i` and `-o` can be set to `-` or omitted to read/write from the
standard input/output.
`-P password_file` can be used to read the password, or an arbitrary
long key (that doesn't have to be text) from a file.
If you don't feel inspired, `-G` prints a random password.
Example - encrypted file transfer:
```sh
nc -l 6666 | tweetpipe -d -p password
tweetpipe -e -p password -i /etc/passwd | nc 127.0.0.1 6666
```
Example - compressed, encrypted archives:
```sh
zstd -5 -v -c "$FILE" | tweetpipe -e -p "$PASSWD" -o "${FILE}.zst.tweetpipe"
```
# Dependencies
None. It includes [tweetnacl](https://tweetnacl.cr.yp.to/). There is nothing to
install.
# Installation
```sh
make
sudo make install
```
# Why
Because I could.
