# `base64encode` Function
|
|
|
|
`base64encode` applies Base64 encoding to a string.
|
|
|
|
Nomad uses the "standard" Base64 alphabet as defined in
|
|
[RFC 4648 section 4](https://tools.ietf.org/html/rfc4648#section-4).
|
|
|
|
Strings in the Nomad language are sequences of unicode characters rather
|
|
than bytes, so this function will first encode the characters from the string
|
|
as UTF-8, and then apply Base64 encoding to the result.
|
|
|
|
The Nomad language applies Unicode normalization to all strings, and so
|
|
passing a string through `base64decode` and then `base64encode` may not yield
|
|
the original result exactly.
|
|
|
|
## Examples
|
|
|
|
```shell-session
|
|
> base64encode("Hello World")
|
|
SGVsbG8gV29ybGQ=
|
|
```
|
|
|
|
## Related Functions
|
|
|
|
- [`base64decode`](/nomad/docs/job-specification/hcl2/functions/encoding/base64decode) performs the opposite operation,
|
|
decoding Base64 data and interpreting it as a UTF-8 string.
