renc

renc is a command-line tool to decode/encode streams using a variety of encodings.

Installation

Grab a binary from the bin/ directory and place it in your $PATH, or use the Makefile.

Usage

renc decodes stdin and re-encodes into stdout. It takes one argument in the form [decoder]:[encoder] (both parts are optional and default to raw).

renc [decoder=raw]:[encoder=raw]

The decoder and encoder parameters can be:

• raw: just let bytes through
• hex: hexadecimal
• base32: standard base32
• base64: standard base64

Examples

Decode raw hex bytes (no re-encoding):

$ echo -n "48656c6c6f20776f726c6421" | renc hex:
Hello world!

Decode base64, then encode into hex:

$ echo -n "SGVsbG8gd29ybGQh" renc base64:hex
48656c6c6f20776f726c6421

Encode a binary file to base64:

$ cat data.bin | renc :base64
