# Base64 Modifier

**Applies to:** Lasernet Core 11

The Base64 modifier is used to encode/decode base 32 or base 64 data. This encoding method is used for converting binary (8-bit) data to 6-bit ASCII-printable data.

## Settings

| **Direction** | Base32 Encode/Decode, Base64 Encode/Decode. |
| --- | --- |
| **URL encoding** | Use an alternate alphabet, called "base64url", which replaces two characters in the alphabet to be more URL-friendly. The default is the regular Base64 alphabet, called simply "base64". |
| **Omit trailing equals** | Omits adding the equal sign padding at the end of the encoded data. The default is to keep the trailing equal sign padding at the end of the encoded data, so the data size is always a multiple of four. |
| **Break lines** | Split the string by a specified number of characters. Useful with MIME, which enforces a limit on line length of base 64-encoded data to 76 characters. |
