Diana OTP: Easy Letter-Based One Time Pad 🔐

In One Time Pad Tutorial video 2, we cover the DIANA OTP, which uses letters and a conversion chart. No math, no codes, no spaces or punctuation, just a conversion/cipher table.

Used by US Special Forces and MACV-SOG during the Viet Nam war, this method is quicker to use when numbers and codes don't need to be sent.
