encrypt the access private key by utilizing the assigned public key;
encrypt a randomly generated key by utilizing the access public key; and
encrypt content utilizing the randomly generated key.
9. The device of claim 8 , wherein the memory and the processor are configured to:
receive a master string of alphanumeric characters; and
encrypt the assigned private key by utilizing a master key that is generated based at least in part on the master string of alphanumeric characters.
10. The device of claim 8 , wherein the memory and the processor are configured to:
decrypt the access private key by utilizing the assigned private key;
decrypt the randomly generated key by utilizing the access private key; and
decrypt the content utilizing the randomly generated key.
11. The device of claim 8 , wherein the randomly generated key is a symmetric key.
12. The device of claim 8 , wherein the memory and the processor are configured to:
encrypt the assigned private key by utilizing a master key that is generated based at least in part on a master string of alphanumeric characters; and
decrypt the access private key by utilizing the assigned private key.
13. The device of claim 8 , wherein the randomly generated key, the access public key, and the access private key are specific to the content.
14. The device of claim 8 , wherein the assigned public key and the assigned private key are associated with the device.
15. A non-transitory computer-readable medium configured to store instructions, which when executed by a processor associated with a device, configure the processor to:
generate an assigned key pair including an assigned public key and an associated assigned private key;
generate, for content to be encrypted, an access key pair including an access public key and an associated access private key;
encrypt the access private key by utilizing the assigned public key;
encrypt a randomly generated key by utilizing the access public key; and
encrypt content utilizing the randomly generated key.
16. The non-transitory computer-readable medium of claim 15 , wherein the processor is configured to:
receive a master string of alphanumeric characters; and
encrypt the assigned private key by utilizing a master key that is generated based at least in part on the master string of alphanumeric characters.
17. The non-transitory computer-readable medium of claim 15 , wherein the processor is configured to:
decrypt the access private key by utilizing the assigned private key;
decrypt the randomly generated key by utilizing the access private key; and
decrypt the content utilizing the randomly generated key.
18. The non-transitory computer-readable medium of claim 15 , wherein the randomly generated key is a symmetric key.
19. The non-transitory computer-readable medium of claim 15 , wherein the processor is configured to:
