Whether the message is encrypted >character by character, string by string or byte by byte? RSA encrypts an entire message at once.

Most such algorithms encrypt messages 8 bytes at a time. -- Wim Lewis / wiml@{omnigroup.com|hhhh.org} / I do not speak for Omni PGP 0x27F772C1: 0C 0D 10 D5 FC 73 D1 35 26 46 42 9E DC 6E 0A 88
