Abstract
Methods and systems for securing information are provided. The method includes generating a hash key by an input/output (I/O) processing module interfacing with a processor executable application to encrypt a block of data of a data container to secure and store the data container; generating cipher text for the block of data encrypted with the hash key; using an encryption key to encrypt the hash key for the block of data; providing the cipher text and the encrypted hash key by the I/O processing module to a storage system for storage; where the I/O processing module segregates the encrypted hash key from the cipher text and maintains the encrypted hash key as part of metadata for the cipher text; and storing the cipher text with the encrypted hash key as the metadata for the cipher text for the block of data.
