Base64 encode

POST /api/base64-encode

Encode arbitrary bytes as base64 (standard or URL-safe). Optional padding stripping for URL-friendly output.

Encodes any bytes as base64. Two flavours are supported: - `variant: "standard"` (default): standard base64 with `+` and `/` (RFC 4648 §4). - `variant: "urlsafe"`: URL-safe base64 with `-` and `_` (RFC 4648 §5) — safe to drop into URLs without further escaping. Set `padding: false` to strip the trailing `=` characters — the common convention for JWTs and similar URL-embedded tokens.
