XorString function

In unit StrUtils

Encode a string by XOR-ing its characters using characters of a given key.

Declaration

pascal

function XorString(const Key: ShortString; const Src: ShortString)
: ShortString

Arguments

`Key`	Key to use.
`Src`	String to encode.

Function result

Resulting string.

Description

XorString encodes the string Src by XOR-ing each character in Source with the corresponding character in Key, repeating Key as often as necessary. The resulting string may contain unreadable characters and may even contain null characters. For this reason it may be a better idea to use the XorEncode function instead, which will representing each resulting ASCII code as a hexadecimal number (of length 2).

Feeding the result again to XorString with the same Key, will result in the original string Src.

Errors

None.
