ABSTRACT:
A method for altering text displayed in a formatted page, including locating a buffer of memory locations containing contents of a formatted page, locating a first text string between two markers within the buffer, the first string being an encrypted text including N characters, replacing the first text string with a second text string within the buffer, the second string being a decrypted text including M characters, where M is less than N, and inserting N-M special fill characters in the N-M unfilled memory locations between the markers within the buffer, so as to avoid the need to move the markers closer together.
