Claim 7:
8. A system for indexing and searching an encrypted archive, the system comprising:
a hardware processor configured to:
generate an encrypted data archive based on a user backup performed using a backup plan with an encryption flag enabled and a user key;

generate an index key for the encrypted data archive by:
creating a string constant and a random key, wherein a combined length of the string constant and the random key is equal to a predetermined value; and
concatenating the string constant, the random key and a backup plan identification value to form the index key;
encrypt the index key using the user key;
store the index key in a secure data storage;
mount the encrypted data archive;
decrypt data in the encrypted data archive using the user key;
generate an index of the encrypted data archive by indexing the decrypted data encrypt the index using the index key; and
receive and execute a search request for the encrypted data archive by mounting, for searching, indices of the index decrypted using the index key in response to verifying that the search request includes the user key.
