Secure Dice

*Currently in BETA*

Secure Dice is a free online dice roller that is mainly geared toward D&D, but can be used for any dice roll you wish. The dice rolls are generated with cryptographically secure pseudo-random integers, to ensure the rolls are as secure as possible. When generating a dice roll, you will be provided a MD5 checksum of the results (more information on this below), and you can choose to email those results to the email address(es) you specify.

Email from the dice server includes a MD5 checksum which can be used to verify that the dice roll sent to you has not been modified. You can perform verification of the roll to ensure the results are genuine by entering the checksum on the verification page.

Never accept a roll sent from anyone other than the Secure Dice server. If the other player forgot to include your email address when generating the dice roll, ask them to roll again: it's the only way to ensure that they sent you the results of a single die roll, rather than the best of many rolls.
