A machine management method includes installing software in a machine including a security device that holds a secret key unextractable from the security device and a public key extractable from the security device, encrypts input data with the public key, and decrypts the input data with the secret key; storing machine identification information of the machine in association with software identification information of the software installed in the machine in an external management apparatus; creating a device-encryption key to encrypt data stored on a first storage device of the machine; storing a device-encryption-key BLOB obtained by encrypting the device-encryption key with the public key on a second storage device of the machine; and storing the device-encryption key in association with the machine identification information in the external management apparatus.
