Methods

(static) verifySignature(signature, signedBlob, publicKeyDer, onComplete)

Check the type of signature and use the publicKeyDer to verify the signedBlob using the appropriate signature algorithm.
Parameters:
Name Type Description
signature Signature An object of a subclass of Signature, e.g. Sha256WithRsaSignature.
signedBlob SignedBlob the SignedBlob with the signed portion to verify.
publicKeyDer Blob The DER-encoded public key used to verify the signature.
onComplete function This calls onComplete(true) if the signature verifies, otherwise onComplete(false).
Source:
Throws:
SecurityException if the signature type is not recognized or if publicKeyDer can't be decoded.

checkSigningPolicy(dataName, certificateName) → {boolean}

Check if the signing certificate name and data name satisfy the signing policy. Your derived class should override.
Parameters:
Name Type Description
dataName Name The name of data to be signed.
certificateName Name The name of signing certificate.
Source:
Returns:
True if the signing certificate can be used to sign the data, otherwise false.
Type
boolean

checkVerificationPolicy(dataOrInterest, stepCount, onVerified, onValidationFailed, wireFormat) → {ValidationRequest}

Check whether the received data or interest packet complies with the verification policy, and get the indication of the next verification step. Your derived class should override.
Parameters:
Name Type Description
dataOrInterest Data | Interest The Data object or interest with the signature to check.
stepCount number The number of verification steps that have been done, used to track the verification progress.
onVerified function If the signature is verified, this calls onVerified(dataOrInterest). NOTE: The library will log any exceptions thrown by this callback, but for better error handling the callback should catch and properly handle any exceptions.
onValidationFailed function If the signature check fails, this calls onValidationFailed(dataOrInterest, reason). NOTE: The library will log any exceptions thrown by this callback, but for better error handling the callback should catch and properly handle any exceptions.
wireFormat WireFormat
Source:
Returns:
The indication of next verification step, or null if there is no further step.
Type
ValidationRequest

inferSigningIdentity(dataName) → {Name}

Infer the signing identity name according to the policy. If the signing identity cannot be inferred, return an empty name. Your derived class should override.
Parameters:
Name Type Description
dataName Name The name of data to be signed.
Source:
Returns:
The signing identity or an empty name if cannot infer.
Type
Name

requireVerify(dataOrInterest) → {boolean}

Check if this PolicyManager has a verification rule for the received data packet or signed interest. Your derived class should override.
Parameters:
Name Type Description
dataOrInterest Data | Interest The received data packet or interest.
Source:
Returns:
True if the data or interest must be verified, otherwise false.
Type
boolean

skipVerifyAndTrust(dataOrInterest) → {boolean}

Check if the received data packet or signed interest can escape from verification and be trusted as valid. Your derived class should override.
Parameters:
Name Type Description
dataOrInterest Data | Interest The received data packet or interest.
Source:
Returns:
True if the data or interest does not need to be verified to be trusted as valid, otherwise false.
Type
boolean
