Mandatory arguments to long options are mandatory for short options too.
- –base64
- same as ‘base64’ program (RFC4648 section 4)
- –base64url
- file- and url-safe base64 (RFC4648 section 5)
- –base32
- same as ‘base32’ program (RFC4648 section 6)
- –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
- –help

When decoding, the input may contain newlines in addition to the bytes of the formal alphabet. Use –ignore-garbage to attempt to recover from any other non-alphabet bytes in the encoded stream.
