Struct SignedDataVerifier 

pub struct SignedDataVerifier { /* private fields */ }

A verifier and decoder class designed to decode signed data from the App Store.

Implementations

impl SignedDataVerifier

pub fn new( root_certificates: Vec<Vec<u8>>, environment: Environment, bundle_id: String, app_apple_id: Option<i64>, enable_online_checks: bool, ) -> Result<Self, SignedDataVerifierError>

Creates a new SignedDataVerifier instance with the specified parameters.

Arguments

• root_certificates - A vector of DER-encoded root certificates used for verification.
• environment - The environment (e.g., Environment::PRODUCTION or Environment::SANDBOX).
• bundle_id - The bundle ID associated with the application.
• app_apple_id - An optional Apple ID associated with the application. Required when environment is Environment::Production.
• enable_online_checks - Whether to check certificate expiration against the current date rather than the JWS’s signed date, and cache the verified public key.

Returns

• Ok(SignedDataVerifier) on success.
• Err(SignedDataVerifierError::InvalidAppAppleId) if environment is Environment::Production and app_apple_id is None.

impl SignedDataVerifier

pub fn verify_and_decode_renewal_info( &self, signed_renewal_info: &str, ) -> Result<JWSRenewalInfoDecodedPayload, SignedDataVerifierError>

Verifies and decodes a signedRenewalInfo obtained from the App Store Server API, an App Store Server Notification, or from a device See JWSRenewalInfo

Arguments

• signed_renewal_info - The signed renewal info string to verify and decode.

Returns

• Ok(JWSRenewalInfoDecodedPayload) if verification and decoding are successful.
• Err(SignedDataVerifierError) if verification or decoding fails, with error details.

pub fn verify_and_decode_signed_transaction( &self, signed_transaction: &str, ) -> Result<JWSTransactionDecodedPayload, SignedDataVerifierError>

Verifies and decodes a signedTransaction obtained from the App Store Server API, an App Store Server Notification, or from a device See JWSTransaction

Arguments

• signed_transaction - The signed transaction string to verify and decode.

Returns

• Ok(JWSTransactionDecodedPayload) if verification and decoding are successful.
• Err(SignedDataVerifierError) if verification or decoding fails, with error details.

pub fn verify_and_decode_notification( &self, signed_payload: &str, ) -> Result<ResponseBodyV2DecodedPayload, SignedDataVerifierError>

Verifies and decodes an App Store Server Notification signedPayload See signedPayload

Arguments

• signed_payload - The signed notification string to verify and decode.

Returns

• Ok(ResponseBodyV2DecodedPayload) if verification and decoding are successful.
• Err(SignedDataVerifierError) if verification or decoding fails, with error details.

pub fn verify_and_decode_app_transaction( &self, signed_app_transaction: &str, ) -> Result<AppTransaction, SignedDataVerifierError>

Verifies and decodes a signed AppTransaction See AppTransaction

Arguments

• signed_app_transaction - The signed app transaction string to verify and decode.

Returns

• Ok(AppTransaction) if verification and decoding are successful.
• Err(SignedDataVerifierError) if verification or decoding fails, with error details.

pub fn verify_and_decode_realtime_request( &self, signed_payload: &str, ) -> Result<DecodedRealtimeRequestBody, SignedDataVerifierError>

Verifies and decodes a realtime request the App Store sends to your Get Retention Message endpoint.

Arguments

• signed_payload - The payload the App Store server sends to your server.

Returns

• Ok(DecodedRealtimeRequestBody) if verification and decoding are successful.
• Err(SignedDataVerifierError) if verification or decoding fails, with error details.
