Struct pkcs8::AlgorithmIdentifier

pub struct AlgorithmIdentifier<'a> {
    pub oid: ObjectIdentifier,
    pub parameters: Option<Any<'a>>,
}

X.509 AlgorithmIdentifier as defined in RFC 5280 Section 4.1.1.2.

AlgorithmIdentifier  ::=  SEQUENCE  {
     algorithm               OBJECT IDENTIFIER,
     parameters              ANY DEFINED BY algorithm OPTIONAL  }

Fields

oid: ObjectIdentifier

Algorithm OID, i.e. the algorithm field in the AlgorithmIdentifier ASN.1 schema.

parameters: Option<Any<'a>>

Algorithm parameters.

Implementations

impl<'a> AlgorithmIdentifier<'a>

pub fn assert_algorithm_oid(
    &self,
    expected_oid: ObjectIdentifier
) -> Result<ObjectIdentifier, Error>

Assert the algorithm OID is an expected value.

pub fn assert_parameters_oid(
    &self,
    expected_oid: ObjectIdentifier
) -> Result<ObjectIdentifier, Error>

Assert parameters is an OID and has the expected value.

pub fn assert_oids(
    &self,
    algorithm: ObjectIdentifier,
    parameters: ObjectIdentifier
) -> Result<(), Error>

Assert the values of the algorithm and parameters OIDs.

pub fn parameters_any(&self) -> Result<Any<'a>, Error>

Get the parameters field as an Any.

Returns an error if parameters are None.

pub fn parameters_oid(&self) -> Result<ObjectIdentifier, Error>

Get the parameters field as an ObjectIdentifier.

Returns an error if it is absent or not an OID.
