Formula and methodology
Formula: Base64 maps 24-bit byte groups to four 6-bit characters and uses = padding when needed.
The implementation encodes Unicode as UTF-8 bytes and rejects invalid standard Base64 alphabets or padding during decoding.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Operation — 2 choices
- Text or Base64 input — Base64 is encoding, not encryption.
Worked example
| Input | Value |
|---|---|
| Operation | encode |
| Text or Base64 input | Hello, world! |
Hello, world! encodes as SGVsbG8sIHdvcmxkIQ==.
Assumptions and limits
- The text mode uses UTF-8.
- The standard RFC 4648 alphabet is used rather than the URL-safe variant.
