Abstract:
1. A method of altering text for display in a formatted page, the method comprising: locating a memory buffer containing character strings and containing markers that delineate the character strings; locating an encrypted character string between two markers within the memory buffer; decoding the encrypted character string to obtain a decrypted character string, the decrypted character string having fewer characters than the encrypted text string; padding the decrypted character string with fill characters so that the padded decrypted character string has the same number of characters as the encrypted character string, wherein the fill characters are characters that are interpreted as non-visible characters by a text formatter that reads the character strings in the memory buffer and derives a page display format therefrom; and overwriting the encrypted character string with the padded decrypted character string in the memory buffer between the two markers.
