Enum x509_certificate::algorithm::DigestAlgorithm

source · [−]

pub enum DigestAlgorithm {
    Sha1,
    Sha256,
    Sha384,
    Sha512,
}

Expand description

A hashing algorithm used for digesting data.

Instances can be converted to and from Oid via From/Into implementations.

They can also be converted to and from The ASN.1 AlgorithmIdentifier, which is commonly used to represent them in X.509 certificates.

Instances can be converted into a digest::Context capable of computing digests via From/Into.

Variants

Implementations

source

impl DigestAlgorithm

source

pub fn digester(&self) -> Context

Obtain an object that can be used to digest content using this algorithm.

source

pub fn digest_data(&self, data: &[u8 ]) -> Vec<u8>

Digest a slice of data.

source

pub fn digest_reader<R: Read>(&self, fh: &mut R) -> Result<Vec<u8>, Error>

Digest content from a reader.

source

pub fn digest_path(&self, path: &Path) -> Result<Vec<u8>, Error>

Digest the content of a path.

source

pub fn rsa_pkcs1_encode(
 &self,
 message: &[u8 ],
 target_length_in_bytes: usize
) -> Result<Vec<u8>, Error>

EMSA-PKCS1-v1_5 padding procedure.

As defined by https://tools.ietf.org/html/rfc3447#section-9.2.

message is the message to digest and encode.

target_length_in_bytes is the target length of the padding. This should match the RSA key length. e.g. 2048 bit keys are length 256.
