- -d, --decode
- decode data
- -i, --ignore-garbage
- when decoding, ignore non-alphabet characters
- -w, --wrap=COLS
- wrap encoded lines after COLS character (default 76). Use 0 to disable line wrapping
- --z85
- ascii85-like encoding (ZeroMQ spec:32/Z85); when encoding, input length must be a multiple of 4; when decoding, input length must be a multiple of 5
