public Cryptword(Cryptword s)

Method Detail

equals

public boolean equals(MyString compareTo)

Tests for equality between this Cryptword string and another string. The exact definition of "equality" depends on the type of the compareTo string. If compareTo is of type Cleartext, then equals returns true if and only if* this string is the encrypted form of compareTo. Thus equals can be used to compare an encrypted string with an unencrypted string, without explicitly encrypting or decrypting either one. In other words, s.toCryptword().equals(s) will always return true.

(*For all practical purposes. It is theoretically possible for two different Cleartext strings to encrypt to the same Cryptword, so the "and only if" part of this assertion is not technically true, though the odds of such "key collisions" are infinitessimal.)

Overrides:

equals in class MyString

Parameters:

compareTo - An instance of MyString to compare to this one for equality.

Returns:

true if this string and the compareTo string are equal, false otherwise. See above for the exact definition of "equal".

toString

public java.lang.String toString(int length)

Gets the first length characters of the encrypted String.
