Claim 11:
12. A computer program product for implementing enhanced file encryption technique, the computer program product comprising a non-transitory computer-readable medium comprising code causing a first apparatus to:
encrypt a file using a local file encryption key to generate an encrypted file;
transmit, via an encryption engine, a first encryption request to an encryption server to encrypt a first portion of the encrypted file;
receive, from the encryption server, an encrypted first portion of the encrypted file based on at least the first encryption request, wherein the first portion of the encrypted file is encrypted by the encryption server using a first file encryption key;
append the encrypted first portion of the encryption file with a remaining portion of the encrypted file to generate a final encrypted file;
transmit, via the encryption engine, a second encryption request to the encryption server to encrypt the local file encryption key;
receive, from the encryption server, an encrypted local file encryption key based on at least the second encryption request;
update the final encrypted file with the encrypted local file encryption key, wherein updating further comprises appending the encrypted local file encryption key with the first portion of the encrypted file and the remaining portion of the encrypted file;
store the final encrypted file in a data repository;
receive an access request from a computing device associated with a user to access the file;
initiate an authentication protocol to determine whether the user is authorized to access the file; and
decrypt the final encrypted file based on at least determining that the user is authorized to access the file.
