NAME

basenc − Encode/decode data and print to standard output

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.
