Enum DigestAlgorithm 

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

Digest algorithms supported by XMLDSig.

SHA-1 is supported for verification only (legacy interop with older IdPs). SHA-256 is the recommended default for new signatures.

Variants

Sha1

SHA-1 (160-bit). Verify-only — signing with SHA-1 is deprecated.

Sha256

SHA-256 (256-bit). Default for SAML.

Sha384

SHA-384 (384-bit).

Sha512

SHA-512 (512-bit).

Implementations

impl DigestAlgorithm

pub fn from_uri(uri: &str) -> Option<Self>

Parse a digest algorithm from its XML namespace URI.

Returns None for unrecognized URIs.

URIs

Algorithm	URI
SHA-1	http://www.w3.org/2000/09/xmldsig#sha1
SHA-256	http://www.w3.org/2001/04/xmlenc#sha256
SHA-384	http://www.w3.org/2001/04/xmldsig-more#sha384
SHA-512	http://www.w3.org/2001/04/xmlenc#sha512

pub fn uri(self) -> &'static str

Return the XML namespace URI for this digest algorithm.

pub fn signing_allowed(self) -> bool

Whether this algorithm is allowed for signing (not just verification).

SHA-1 is deprecated and restricted to verify-only for interop with legacy IdPs.

pub fn output_len(self) -> usize

The expected output length in bytes.

Trait Implementations

impl Clone for DigestAlgorithm

fn clone(&self) -> DigestAlgorithm

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for DigestAlgorithm

impl Debug for DigestAlgorithm

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DigestAlgorithm

impl Hash for DigestAlgorithm

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DigestAlgorithm

fn eq(&self, other: &DigestAlgorithm) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
