Abstract
An information processing apparatus includes processing circuitry. The processing circuitry writes an encryption key file that is encrypted into a second storage. The encryption key file includes first encryption key data and a first hash value of the first encryption key data. The first encryption key data is used for decrypting data stored in a first storage. The processing circuitry decrypts the encryption key file that is encrypted using a second encryption key data to obtain the encryption key file that is decrypted. The processing circuitry calculates a second hash value from the first encryption key data included in the encryption key file that is decrypted. The processing circuitry performs verification of the second encryption key data based on a determination of whether the first hash value matches the second hash value. The processing circuitry notify a verification result when the verification fails.
