Struct cryptoki::mechanism::MechanismInfo

pub struct MechanismInfo { /* private fields */ }

Information about a particular mechanism

Implementations

impl MechanismInfo

pub fn min_key_size(&self) -> usize

The minimum size of the key for the mechanism

Conformance: Whether this is measured in bits or in bytes is mechanism-dependent. For some mechanisms, this field may be meaningless and take any value.

pub fn max_key_size(&self) -> usize

The maximum size of the key for the mechanism

Conformance: Whether this is measured in bits or in bytes is mechanism-dependent For some mechanisms, this field may be meaningless and take any value.

pub fn hardware(&self) -> bool

True if the mechanism is performed by the device; false if the mechanism is performed in software

pub fn encrypt(&self) -> bool

True if the mechanism can be used to encrypt data

See Session::encrypt

pub fn decrypt(&self) -> bool

True if the mechanism can be used to decrypt encrypted data

See Session::decrypt

pub fn digest(&self) -> bool

True if the mechanism can be used to digest a message

pub fn sign(&self) -> bool

True if the mechanism can be used to digitally sign data

See Session::sign

pub fn sign_recover(&self) -> bool

True if the mechanism can be used to digitally data which can be recovered from the signature

pub fn verify(&self) -> bool

True if the mechanism can be used to verify a digital signature

See Session::verify

pub fn verify_recover(&self) -> bool

True if the mechanism can be used to verify a digital signature and recover the signed data

pub fn generate(&self) -> bool

True if the mechanism can be used to generate a secret key

pub fn generate_key_pair(&self) -> bool

True if the mechanism can be used to generate a public/private key pair

See Session::generate_key_pair)

pub fn wrap(&self) -> bool

True if the mechanism can be used to wrap (encrypt) a key

pub fn unwrap(&self) -> bool

True if the mechanism can be used to unwrap (decrypt) a key

pub fn derive(&self) -> bool

True if the mechanism can be used to derive a key from a base key

pub fn extension(&self) -> bool

True if there is an extension to the flags; false if no extensions

Conformance: This must be false for PKCS#11 v2.40

pub fn ec_f_p(&self) -> bool

True if the mechanism can be used to with elliptic curve domain parameters over F_p

Conformance: At least one of ec_f_p and ec_f_2m must be true

pub fn ec_f_2m(&self) -> bool

True if the mechanism can be used with elliptic curve domain parameters over F_2^m

Conformance: At least one of ec_f_p and ec_f_2m must be true

pub fn ec_from_parameters(&self) -> bool

True if the mechanism supports specifying elliptic curve domain parameters explicitly

Conformance: At least one of ec_from_parameters and ec_from_named_curve must be true

pub fn ec_from_named_curve(&self) -> bool

True if the mechanism supports specifying elliptic curve domain parameters with a named curve

Conformance: At least one of ec_from_parameters and ec_from_named_curve must be true

pub fn ec_uncompressed(&self) -> bool

True if the mechanism can be used with elliptic curve points in uncompressed form

Conformance: At least one of ec_uncompressed and ec_compressed must be true

pub fn ec_compressed(&self) -> bool

True if the mechanism can be used with elliptic curve points in compressed form

Conformance: At least one of ec_uncompressed and ec_compressed must be true
