Enum PowParams

#[non_exhaustive]
pub enum PowParams {
    V1(PowParamsV1),
}

Available on crate feature hs-common only.

The contents of a pow-params line with any recognized scheme.

These use a text format defined by: https://spec.torproject.org/rend-spec/hsdesc-encrypt.html#second-layer-plaintext

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

V1(PowParamsV1)

Parameters for the v1 scheme

This scheme uses the Equi-X asymmetric puzzle, in an iterated construction with Blake2b for effort adjustment. The Tor specification describes this puzzle construction and references the underlying algorithms:

Implementations

impl PowParams

fn try_from_item(item: &Item<'_, HsInnerKwd>) -> Result<Option<Self>>

Parse a single pow-params line from an Item

If the scheme is recognized, returns a PowParams or a parse error. If the scheme is unknown, returns None. If the scheme field is missing entirely, returns a parse error.
