Mandatory arguments to long options are mandatory for short options too.

--base32hex

extended hex alphabet base32 (RFC4648 section 7)

--base16

hex encoding (RFC4648 section 8)

--base2msbf

bit string with most significant bit (msb) first

--base2lsbf

bit string with least significant bit (lsb) first

-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
