NAME

fastbase64.coreutils - base64 encode/decode data and print to standard output (coreutils compatible)

SYNOPSIS

fastbase64.coreutils [OPTIONS...] [INPUTFILE]

DESCRIPTION

fastbase64.coreutils encodes or decodes base64 data using the high-performance simdutf library, with options compatible with GNU coreutils base64, plus clearly marked fastbase64-specific extensions. By default, it encodes binary input to base64 output. On large files, it can be several times faster than standard base64 tools.

fastbase64 extension (not present in GNU coreutils base64): If a second filename is provided, it is used as the output file. Otherwise, output goes to standard output. The -o option takes precedence over positional output file.

OPTIONS

-b, --break=NUM

synonym to --wrap. (not in GNU coreutils base64)

-w, --wrap=NUM

Wrap encoded lines after NUM characters (default 76). Use 0 to disable line wrapping.

-d, -D, --decode

Decode input.

-e, --encode

Encode input (default).

--ignore-garbage

When decoding, ignore non-alphabet characters.

-i, -n, --noerrcheck

fastbase64 extension (not present in GNU coreutils base64): when decoding, ignore non-alphabet characters (same as --ignore-garbage).

-h, --help

Display help message and exit.

-o, --output=FILE

fastbase64 extension (not present in GNU coreutils base64): output file (default: "-" for stdout).

--version

Output version information and exit.

EXAMPLES

Encode a file:

fastbase64.coreutils myfile.txt

Decode base64 data ignoring garbage:

fastbase64.coreutils -d -i < encoded.txt
