Method Detail

generate

public void generate(Interest interest,
            KeyChain keyChain,
            Name certificateName,
            WireFormat wireFormat)
              throws SecurityException

Append a timestamp component and a random value component to interest's name. This ensures that the timestamp is greater than the timestamp used in the previous call. Then use keyChain to sign the interest which appends a SignatureInfo component and a component with the signature bits. If the interest lifetime is not set, this sets it.

Parameters:

interest - The interest whose name is append with components.

keyChain - The KeyChain for calling sign.

certificateName - The certificate name of the key to use for signing.

wireFormat - A WireFormat object used to encode the SignatureInfo and to encode interest name for signing.

Throws:

SecurityException

generate

public void generate(Interest interest,
            KeyChain keyChain,
            Name certificateName)
              throws SecurityException

Append a timestamp component and a random value component to interest's name. This ensures that the timestamp is greater than the timestamp used in the previous call. Then use keyChain to sign the interest which appends a SignatureInfo component and a component with the signature bits. If the interest lifetime is not set, this sets it. Use the default WireFormat to encode the SignatureInfo and to encode interest name for signing.

Parameters:

interest - The interest whose name is append with components.

keyChain - The KeyChain for calling sign.

certificateName - The certificate name of the key to use for signing.

Throws:

SecurityException
