Managing access to data
A method including receiving, by a user device, encrypted content and an encrypted assigned private key associated with the encrypted content; decrypting, by the user device, the encrypted assigned private key based at least in part on utilizing a master key to determine a decrypted assigned private key; determining, by the user device, a combination decryption key based at least in part on utilizing the decrypted assigned private key and an access public key associated with the encrypted content; decrypting, by the user device, an encrypted access private key associated with the access public key to determine a decrypted access private key; and decrypting, by the user device, the encrypted content based at least in part on utilizing the decrypted access private key is disclosed. Various other aspects are contemplated.
1. A method, comprising:

decrypting, by the user device, an encrypted access private key associated with the access public key to determine a decrypted access private key; and
decrypting, by the user device, the encrypted content based at least in part on utilizing the decrypted access private key.
2. The method of claim 1 , further comprising:
determining, by the user device, the master key based at least in part on receiving an input master string.
3. The method of claim 1 , wherein determining the combination decryption key includes combining the decrypted assigned private key and the access public key.
4. The method of claim 1 , wherein decrypting the encrypted content includes decrypting an encrypted symmetric key based at least in part on utilizing the decrypted access private key.
5. The method of claim 1 , wherein decrypting the encrypted content includes decrypting the encrypted content based at least in part on utilizing a decrypted symmetric key, which is decrypted based at least in part on utilizing the decrypted access private key.
6. The method of claim 1 , wherein the combination decryption key is symmetric.
7. The method of claim 1 , wherein receiving the encrypted content includes transmitting a request for receiving the encrypted content.
8. A user device, comprising:
a memory; and
a processor communicatively coupled to the memory, the memory and the processor being configured to:
receive encrypted content and an encrypted assigned private key associated with the encrypted content;
decrypt the encrypted assigned private key based at least in part on utilizing a master key to determine a decrypted assigned private key;
determine a combination decryption key based at least in part on utilizing the decrypted assigned private key and an access public key associated with the encrypted content;
decrypt an encrypted access private key associated with the access public key to determine a decrypted access private key; and
decrypt the encrypted content based at least in part on utilizing the decrypted access private key.
9. The user device of claim 8 , wherein the memory and the processor are configured to:
determine the master key based at least in part on receiving an input master string.
10. The user device of claim 8 , wherein, to determine the combination decryption key, the memory and the processor are configured to combine the decrypted assigned private key and the access public key.
11. The user device of claim 8 , wherein, to decrypt the encrypted content, the memory and the processor are configured to decrypt an encrypted symmetric key based at least in part on utilizing the decrypted access private key.
12. The user device of claim 8 , wherein, to decrypt the encrypted content, the memory and the processor are configured to decrypt the encrypted content based at least in part on utilizing a decrypted symmetric key, which is decrypted based at least in part on utilizing the decrypted access private key.
13. The user device of claim 8 , wherein the combination decryption key is symmetric.
14. The user device of claim 8 , wherein, to receive the encrypted content, the memory and the processor are configured to transmit a request for receiving the encrypted content.
15. A non-transitory computer-readable medium configured to store instructions, which when executed by a processor associated with a user device, configure the processor to:
receive encrypted content and an encrypted assigned private key associated with the encrypted content;
decrypt the encrypted assigned private key based at least in part on utilizing a master key to determine a decrypted assigned private key;
determine a combination decryption key based at least in part on utilizing the decrypted assigned private key and an access public key associated with the encrypted content;
decrypt an encrypted access private key associated with the access public key to determine a decrypted access private key; and
decrypt the encrypted content based at least in part on utilizing the decrypted access private key.
16. The non-transitory computer-readable medium of claim 15 , wherein the processor is configured to:
determine the master key based at least in part on receiving an input master string.
17. The non-transitory computer-readable medium of claim 15 , wherein, to determine the combination decryption key, the processor is configured to combine the decrypted assigned private key and the access public key.
18. The non-transitory computer-readable medium of claim 15 , wherein, to decrypt the encrypted content, the processor is configured to decrypt an encrypted symmetric key based at least in part on utilizing the decrypted access private key.
19. The non-transitory computer-readable medium of claim 15 , wherein, to decrypt the encrypted content, the processor is configured to decrypt the encrypted content based at least in part on utilizing a decrypted symmetric key, which is decrypted based at least in part on utilizing the decrypted access private key.
20. The non-transitory computer-readable medium of claim 15 , wherein the combination decryption key is symmetric.
