Struct sd_jwt_payload::SdObjectDecoder

pub struct SdObjectDecoder { /* private fields */ }

Substitutes digests in an SD-JWT object by their corresponding plain text values provided by disclosures.

Implementations

impl SdObjectDecoder

pub fn new_with_sha256() -> Self

Creates a new SdObjectDecoder with sha-256 hasher.

pub fn new() -> Self

Creates a new SdObjectDecoder without any hashers.

pub fn add_hasher(&mut self, hasher: Box<dyn Hasher>) -> Option<Box<dyn Hasher>>

Adds a hasher.

If a hasher for the same algorithm Hasher::alg_name already exists, it will be replaced and the existing hasher will be returned, otherwise None.

pub fn remove_hasher(&mut self, hash_alg: String) -> Option<Box<dyn Hasher>>

Removes a hasher.

If the hasher for that algorithm exists, it will be removed and returned, otherwise None.

pub fn decode( &self, object: &Map<String, Value>, disclosures: &Vec<String> ) -> Result<Map<String, Value>, Error>

Decodes an SD-JWT object containing by Substituting the digests with their corresponding plain text values provided by disclosures.

Notes

• The hasher is determined by the _sd_alg property. If none is set, the sha-256 hasher will be used, if present.
• Claims like exp or iat are not validated in the process of decoding.
• _sd_alg property will be removed if present.

pub fn determine_hasher( &self, object: &Map<String, Value> ) -> Result<&dyn Hasher, Error>
