Class Verification

NSObject
- Verification

Verification

A Verification object contains result of a gateway’s attempt to verify one of the signatures on signed data. The gateway verify methods return an array of Verification objects, one for each signature in the data. The Verification object provides information on whether the signature was cryptographically valid, whether the identity of the signature’s owner is known as a contact, and other attributes.

Applications should use the information provided to implement logic about whether to accept the data and how to handle errors.

Constructors

The Verification object should not be instantiated directly by the developer, as it is instantiated and returned by gateway cryptographic verification methods.

Instance Methods

Return Type Method and Description

Return Type	Method and Description
`NSNumber *`	`isVerified :(NSError **) error` Determines whether data’s signature was cryptographically verified with the public key specified in a signed data structure..
`bool`	`(BOOL) signerIsKnown :(NSError **) error` Determines whether data’s signature public key is contained in a locally stored keychain of either either an internal persona or a previously paired contact.
`Facade *`	`getFacade :(NSError **) error` Get the `facade` that is associated internally with the data’s public key. The data’s public key (or a reference to it) is included in the signed data string.
`NSNumber *`	`getTimestamp :(NSError **) error` The time the signature was added to the signed data, expressed in milliseconds since Jan 1, 1970.
`NSString *`	`getSignature :(NSError **) error` Gets the signature associated with the `Verification`.
`NSString *`	`getPublicKey :(NSError **) error` Gets the public key associated with the `Verification`.
`NSString *`	`getPublicKeyId :(NSError **) error` Gets the public key ID associated with the `Verification`.
`NSNumber *`	`isApproval :(NSError **) error` Determines if the `Verification` represents an approval or not.

NSNumber *

isVerified :(NSError **) error

Determines whether data’s signature was cryptographically verified with the public key specified in a signed data structure..

bool

(BOOL) signerIsKnown :(NSError **) error

Determines whether data’s signature public key is contained in a locally stored keychain of either either an internal persona or a previously paired contact.

Facade *

getFacade :(NSError **) error

Get the facade that is associated internally with the data’s public key. The data’s public key (or a reference to it) is included in the signed data string.

NSNumber *

getTimestamp :(NSError **) error

The time the signature was added to the signed data, expressed in milliseconds since Jan 1, 1970.

NSString *

getSignature :(NSError **) error

Gets the signature associated with the Verification.

NSString *

getPublicKey :(NSError **) error

Gets the public key associated with the Verification.

NSString *

getPublicKeyId :(NSError **) error

Gets the public key ID associated with the Verification.

NSNumber *

isApproval :(NSError **) error

Determines if the Verification represents an approval or not.
