Character Permutation and Character Substitution

Two algorithms that manipulate character of a given string.

The character permutation data masking algorithm uses characters of a given string as an input set and maps this set on itself by creating various permutations of the characters of the string either randomly or in pre-defined repeatable pattern.

The character substitution data masking algorithm besides a given string uses another set of the characters with the specific mapping rules, creating an output based on either random or predefined mappings.

The strongest masking algorithm of this variety is random character substitution, followed by random character permutation and pre-defined character substitution, followed by pre-defined character permutation.
