In one embodiment, a passphrase is enciphered. An archive key used to encipher an archive is enciphered with the enciphered passphrase. A first enciphered block is computed by enciphering a random block with the archive key. A second enciphered block is computed by enciphering the same random block with a Message Authentication Code (MAC) key. The MAC key is derived from the archive key and the passphrase. The validity of keys is determined by comparing the decrypted first block with the decrypted second block."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Validating encrypted archive keys","description":"An apparatus and a method for validating encrypted archive keys is described.
