Detailed Description
Keymaster0 device definition.

Field Documentation
uint32_t client_version |
THIS IS DEPRECATED. Use the new "module_api_version" and "hal_api_version" fields in the keymaster_module initialization instead.
Definition at line 40 of file keymaster0.h .
struct hw_device_t common |
Common methods of the keymaster device. This must be the first member of keymaster0_device as users of this structure will cast a hw_device_t to keymaster0_device pointer in contexts where it's known the hw_device_t references a keymaster0_device .
Definition at line 34 of file keymaster0.h .
void* context |
Definition at line 47 of file keymaster0.h .
int(* delete_all)(const struct keymaster0_device *dev) |
Deletes all keys in the hardware keystore. Used when keystore is reset completely.
This function is optional and should be set to NULL if it is not implemented.
Returns 0 on success or an error code less than 0.
Definition at line 102 of file keymaster0.h .
int(* delete_keypair)(const struct keymaster0_device *dev, const uint8_t *key_blob, const size_t key_blob_length) |
Deletes the key pair associated with the key blob.
This function is optional and should be set to NULL if it is not implemented.
Returns 0 on success or an error code less than 0.
Definition at line 90 of file keymaster0.h .
uint32_t flags |
See flags defined for keymaster0_device::flags in keymaster_common.h
Definition at line 45 of file keymaster0.h .
int(* generate_keypair)(const struct keymaster0_device *dev, const keymaster_keypair_t key_type, const void *key_params, uint8_t **key_blob, size_t *key_blob_length) |
Generates a public and private key. The key-blob returned is opaque and must subsequently provided for signing and verification.
Returns: 0 on success or an error code less than 0.
Definition at line 55 of file keymaster0.h .
int(* get_keypair_public)(const struct keymaster0_device *dev, const uint8_t *key_blob, const size_t key_blob_length, uint8_t **x509_data, size_t *x509_data_length) |
Gets the public key part of a key pair. The public key must be in X.509 format (Java standard) encoded byte array.
Returns: 0 on success or an error code less than 0. On error, x509_data should not be allocated.
Definition at line 78 of file keymaster0.h .
int(* import_keypair)(const struct keymaster0_device *dev, const uint8_t *key, const size_t key_length, uint8_t **key_blob, size_t *key_blob_length) |
Imports a public and private key pair. The imported keys will be in PKCS#8 format with DER encoding (Java standard). The key-blob returned is opaque and will be subsequently provided for signing and verification.
Returns: 0 on success or an error code less than 0.
Definition at line 67 of file keymaster0.h .
int(* sign_data)(const struct keymaster0_device *dev, const void *signing_params, const uint8_t *key_blob, const size_t key_blob_length, const uint8_t *data, const size_t data_length, uint8_t **signed_data, size_t *signed_data_length) |
Signs data using a key-blob generated before. This can use either an asymmetric key or a secret key.
Returns: 0 on success or an error code less than 0.
Definition at line 110 of file keymaster0.h .
int(* verify_data)(const struct keymaster0_device *dev, const void *signing_params, const uint8_t *key_blob, const size_t key_blob_length, const uint8_t *signed_data, const size_t signed_data_length, const uint8_t *signature, const size_t signature_length) |
Verifies data signed with a key-blob. This can use either an asymmetric key or a secret key.
Returns: 0 on successful verification or an error code less than 0.
