We have updated our Decode and Destroy (https://www.decodeanddestroy.com) Web Service that'll send encrypted data that can only be retrieved by the recipient. (Passwords, Social Security Numbers, Account Numbers, Messages, etc.)
This is a free service from Inline Technology.
Decode and Destroy is a service that temporally stores encrypted messages that can only be retrieved by an individual that is given the proper website link. Once the message is retrieved the first time, it will be deleted and no longer be available from subsequent attempts. If the message is not retrieved within 24 hours, it will be automatically deleted.
Messages are automatically encoded with the Rijndael encryption algorithm using a random key and stored in the Decode and Destroy database. The key is provided in the website link and is not stored by Decode and Destroy so we do not have access to the plaintext contents of the message.
A user simply clicks on the link created by Decode and Destroy where he/she will be able to easily retrieve the message.
Optionally, a user can specify a strong password that can be used as the key to encrypt the message. When a password is used, the recipient of the message will be prompted to enter the password after he/she clicks on the website link. As with the automatically generated key, we do not record the password and do not have access to the contents of the plaintext message.
