A simple command-line utility written in Go that supports both Blowfish and Twofish.

fish supports reading the encryption key securely from a prompt or passed via the -k option. You may use other UNIX tools such as base64 to encode the resulting cipher text for portability.

Getting Started

Install from Releases

You can install fish by simply downloading the latest version from the Release page for your platform and placing the binary in your $PATH.

For convenience you can run one of the following shell pipelines which will download and install the latest release binary into /usr/local/bin (modify to suit):

For Linux x86_64:

curl -s | grep browser_download_url | grep Linux_x86_64 | cut -d '"' -f 4 | wget -q -O - -i - | tar -xv fish && mv fish /usr/local/bin/fish

For MacOS x86_64:

curl -s | grep browser_download_url | grep Darwin_x86_64 | cut -d '"' -f 4 | wget -q -O - -i - | tar -xv fish && mv fish /usr/local/bin/fish

For Windows, there are published binaries as well. Download and place in your environment as appropriate.

Install from Homebrew

On MacOS you can install fish using Homebrew:

brew tap prologic/fish
brew install fish
Install from Source

To install fish from source you can run go get directly if you have a Go environment setup:

go get

NOTE: Be sure to have $GOBIN (if not empty) or your $GOPATH/bin in your $PATH. See Compile and install packages and dependencies

Or grab the source code and build:

git clone
cd fish
make build

And optionally run make install to place the binary fish in your $GOBIN or $GOPATH/bin (again see note above).



$ echo 'Hell World' | ./fish -e -k "$(pwgen 16 1)" - | base64


$ echo "AAAAAAAAAAAnQWrQ/Dw26TjqTfxqve87" | base64 -d | ./fish -d -k "${key}" -
Hell World

Add the -2 option to use Twofish instead of Blowfish (//the default//).
