One-to-many cryptographic systems and methods are disclosed, including numerous industry applications. Embodiments of the present invention can generate and regenerate the same symmetric key from a random token. The one-to-many cryptographic systems and methods include a cryptographic module being in communication with one or more remote locations. The cryptographic module is configured to encrypt data received from the remote locations and to decrypt data for receipt by the remote locations. The cryptographic module includes a key generator configured to use two or more inputs to reproducibly generate the symmetric key and a cryptographic engine configured to use the symmetric key for encrypting and decrypting data. Corresponding methods are also provided.
