renc is a command-line tool to decode/encode streams using a variety of encodings.
Grab a binary from the bin/ directory and place it in your $PATH, or use the Makefile.
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 throughhex: hexadecimalbase32: standard base32base64: standard base64
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
