Method SecureKey():toString() Professional
Converts the binary key to a hexadecimal notation.
:toString([<cBin>], [<cSeparator>], [<nGroup>]) --> cHexString
Returns a character string. The returned string is longer than the binary representation of the key, depending on <cSeparator> and <nGroup>.
The method :toString() can be used to return a key in hexadecimal notation. Passing a cipher key to the designated user of the key is done easier if the key can be passed in written formats rather than in electronic formats only. To create a key using the hexadecimal notation, use :toBin().
