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 _zsingle_quotesz_base64_zsingle_quotesz_ program (RFC4648 section 4)
−−base64url: file− and url−safe base64 (RFC4648 section 5)
−−base32: same as _zsingle_quotesz_base32_zsingle_quotesz_ 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.
