The facts on the card
The card carries these facts from its Wikipedia article.
- It requires the use of a single-use pre-shared key that is larger than or equal to the size of the message being sent.
- In this technique, a plaintext is paired with a random secret key.
- Then, each bit or character of the plaintext is encrypted by combining it with the corresponding bit or character from the pad using modular addition.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The One-time pad article was read about 180,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 58: each hit it takes is cut by 23 %.
How to get One-time pad
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
