Classification: CPC G | IPC G

Claim 9:
10. The system of claim 9, wherein the non-transitory computer-readable medium further comprises code configured to cause the at least one processing device to:
transmit, via the encryption engine, a first decryption request to the encryption server to decrypt the encrypted first portion of the encrypted file, wherein the first decryption request comprises the encrypted first portion of the encrypted file;
receive, from the encryption server, the first portion of the encrypted file based on at least the first decryption request, wherein the first portion of the encrypted file is decrypted by the encryption server using the first file encryption key;
transmit, via the encryption engine, a second decryption request to the encryption server to decrypt the encrypted local file encryption key, wherein the second decryption request comprises the encrypted first file encryption key;
receive, from the encryption server, the local file encryption key based on at least the second decryption request, wherein the encrypted local file encryption key is decrypted by the encryption server using the second file encryption key
transmit, via the encryption engine, a third decryption request to the encryption server to decrypt the encrypted checksum, wherein the third decryption request comprises the encrypted checksum; and
receive, from the encryption server, the checksum based on at least the third decryption request, wherein the encrypted checksum is decrypted by the encryption server using the third file encryption key.
