Parsed WWW-Authenticate header for Digest auth challenge

Represents a server’s Digest authentication challenge as defined in RFC 2617. Example header: Digest realm="aria2", nonce="abc123", qop="auth", algorithm="MD5"

Fields

realm: String

Authentication realm (typically a human-readable string describing the protected area)

nonce: String

Server-provided nonce value (unique per challenge)

qop: Option<String>

Quality of protection: “auth” or “auth-int” (optional)

algorithm: String

Hash algorithm used (default “MD5”)

opaque: Option<String>

Opaque value that client must return unchanged (optional)

stale: bool

If true, the previous attempt failed due to stale nonce

Implementations

impl DigestAuthChallenge

pub fn parse(header_value: &str) -> Result<Self, Aria2Error>

Parse a WWW-Authenticate header value containing a Digest challenge.

Arguments

• header_value - The full header value, e.g. Digest realm="aria2", nonce="abc123", qop="auth", algorithm="MD5", opaque="xyz", stale=false

Returns

A parsed DigestAuthChallenge on success, or an error message on failure.

Errors

Returns an error if:

• The header does not start with “Digest “
• The required nonce parameter is missing

Example

let challenge = DigestAuthChallenge::parse(
    r#"Digest realm="test realm", nonce="dcd98b7102dd2f0e8b11d0f600bfb0c093", qop="auth""#
).unwrap();
assert_eq!(challenge.realm, "test realm");
assert_eq!(challenge.nonce, "dcd98b7102dd2f0e8b11d0f600bfb0c093");
