# base64
> Encode or decode file or `stdin` to/from Base64, to `stdout`.
> More information: <https://www.gnu.org/software/coreutils/base64>.
- Encode the contents of a file as base64 and write the result to `stdout`:
`base64 {{path/to/file}}`
- Wrap encoded output at a specific width (`0` disables wrapping):
`base64 --wrap {{0|76|...}} {{path/to/file}}`
- Decode the base64 contents of a file and write the result to `stdout`:
`base64 --decode {{path/to/file}}`
- Encode from `stdin`:
`{{somecommand}} | base64`
- Decode from `stdin`:
`{{somecommand}} | base64 --decode`
