pub struct AlgorithmIdentifier {
    pub oid: ObjectIdentifier,
    pub parameters: Option<AlgorithmParameters>,
}

X.509 AlgorithmIdentifier

Defined in RFC 5280 Section 4.1.1.2: https://tools.ietf.org/html/rfc5280#section-4.1.1.2

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

Fields

oid: ObjectIdentifier

Algorithm OID.

This is the algorithm field in the AlgorithmIdentifier ASN.1 schema.

parameters: Option<AlgorithmParameters>

Algorithm parameters.

According to RFC 5280, this technically contains algorithm-defined ANY data, however as this crate is specialized to RSA and ECC keys, we only support an OID in this field.

Implementations

impl AlgorithmIdentifier

pub fn from_der(bytes: &[u8]) -> Result<Self>

Parse AlgorithmIdentifier encoded as ASN.1 DER

pub fn write_der<'a>(&self, buffer: &'a mut [u8]) -> Result<&'a [u8]>

Write ASN.1 DER-encoded AlgorithmIdentifier to the provided buffer, returning a slice containing the encoded data.

pub fn to_der(&self) -> Vec<u8>

This is supported on crate feature alloc only.

Encode this AlgorithmIdentifier as ASN.1 DER
