Claim 14:
15. A non-transitory computer readable medium storing thereon computer executable instructions for indexing and searching an encrypted archive, comprising instructions for:
generating an encrypted data archive based on a user backup performed using a backup plan with an encryption flag enabled and a user key;
generating 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;

encrypting the index key using the user key;
storing the index key in a secure data storage;
mounting the encrypted data archive;
decrypting data in the encrypted data archive using the user key;
generating an index of the encrypted data archive by indexing the decrypted data encrypting the index using the index key; and
receiving and executing 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.
