NAME¶

fastbase64 - base64 encode/decode data and print to standard output

SYNOPSIS¶

fastbase64 [-Ddh] [-b num] [-i in_file] [-o out_file]

DESCRIPTION¶

fastbase64 encodes or decodes base64 data using the high-performance simdutf library. By default, it encodes binary input to base64 output. On large files, it can be several times faster than standard base64 tools. If a second filename is provided, it is used as the output file. Otherwise, output goes to standard output.

OPTIONS¶

-b, --break num

break encoded output up into lines of length num (default 0, meaning no breaks)

-D, -d, --decode

decode input

-h, --help

display this message

-i, --input in_file

input file (default: "-" for stdin)

-o, --output out_file

output file (default: "-" for stdout)

-w, --wrap=NUM

same as -b

-e, --encode

encode input (default)

--ignore-garbage

when decoding, ignore non-alphabet characters

--version

output version information and exit

EXAMPLES¶

Encode a file (default, no wrapping):

fastbase64 -i myfile.txt

Decode base64 data:

fastbase64 -d -i encoded.txt

Encode with custom line wrapping:

fastbase64 -b 76 -i myfile.txt
