org.bouncycastle.operator
Interface ContentSigner

All Known Implementing Classes:
BufferingContentSigner

public interface ContentSigner

General interface for an operator that is able to create a signature from a stream of output.


Method Summary
 org.bouncycastle.asn1.x509.AlgorithmIdentifier getAlgorithmIdentifier()
          Return the algorithm identifier describing the signature algorithm and parameters this signer generates.
 java.io.OutputStream getOutputStream()
          Returns a stream that will accept data for the purpose of calculating a signature.
 byte[] getSignature()
          Returns a signature based on the current data written to the stream, since the start or the last call to getSignature().
 

Method Detail

getAlgorithmIdentifier

public org.bouncycastle.asn1.x509.AlgorithmIdentifier getAlgorithmIdentifier()
Return the algorithm identifier describing the signature algorithm and parameters this signer generates.

Returns:
algorithm oid and parameters.

getOutputStream

public java.io.OutputStream getOutputStream()
Returns a stream that will accept data for the purpose of calculating a signature. Use org.bouncycastle.util.io.TeeOutputStream if you want to accumulate the data on the fly as well.

Returns:
an OutputStream

getSignature

public byte[] getSignature()
Returns a signature based on the current data written to the stream, since the start or the last call to getSignature().

Returns:
bytes representing the signature.
