Command line utility to pipe one input encoding to another encoding

This utility requires nodejs to be installed.

Then, install the normal way with:

npm install -g pipe-transform-cli

Run it from the command line:

pipetransform [input encoding] [output encoding]

Supported input and output encodings are:

• binary
• utf8
• hex
• base64
• base64url

For example, pipe the openssl hashing output to turn it to base64url:

openssl dgst -sha256 -binary text.txt | pipetransform binary base64url

If the input encoding is utf8, base64, base64url, or hex, the final trailing newline will be stripped.

With the trailing newline stripped the output is:

echo words | pipetransform --trim utf8 hex # => 776f726473

While without the trim, the output would have been different:

echo words | bad-pipetransform --trim utf8 hex # => 776f7264730a
