NAME

basenc – Encode/decode data and print to standard output

SYNOPSIS

basenc [,OPTION/]… [,FILE/]

DESCRIPTION

basenc encode or decode FILE, or standard input, to standard output.

With no FILE, or when FILE is -, read standard input.

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

display this help and exit

–version

output version information and exit

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.
