# XorDecode

Decode a string encoded with XorEncode

## Declaration

Source position: strutils.pp line 164

`function XorDecode(`
`const Key: String;`
`const Source: String`
`):String;`

## Arguments

`Key` |  | Key to use when decoding.
`Source` |  | String to decode

## Function result

Hexadecimal representation of the XOR-encoded string.

## Description

XorDecode decodes Source and returns the original string that was encrypted using XorEncode with key Key. If a different key is used than the key used to encode the string, the result will be unreadable.

## Errors

If the string Source is not a valid XorEncode result (e.g. contains non-numerical characters), then a EConversionError exception will be raised.
