KeyNotes encrypts the build-in memos and paintings created by KeyNotes using the blowfish algorithm and a 448-bit key. You can encrypt single records or a complete category. By encrypting a category you can select or create a destination category for the encrypted records. KeyNotes also has a new frontend for memos which display the header and the beginning of the first two paragraphs for a better navigation. For exchange with other devices KeyNotes supports beaming of single records and categories. KeyNotes1.0 doesn´t support Palm OS 5.
