[Mono-list] Which algorithm to crypt strings ?

[Salvatore Scarciglia]

Hi all,
what's the simplest algorithm (and related Class) to, given a well known
string, crypt and encrypt another string using the first as key for
cryptography ??
Something lik this:

...
...
ClassForCrypt X = new ClassForCrypt();
X.key = well_known_string;
string crypted = X.Crypt("string to be crypted");
string decrypted = X.Decrypt("string to be decrypted");
...
...


Thanx
Sas
