public class SignerInfos

extends DERSetPr

SignerInfos class is DER encoded container, represented in ASN.1 notation according to RFC2630, used for storing individual information about each signer of the signed message. Beside other information, SignerInfos class contains signature of the message.

SignerInfos ::= SET OF SignerInfo

SignerInfo ::= SEQUENCE {

version CMSVersion,

sid SignerIdentifier,

digestAlgorithm DigestAlgorithmIdentifier,

signedAttrs [0] IMPLICIT SignedAttributes OPTIONAL,

signatureAlgorithm SignatureAlgorithmIdentifier,

signature SignatureValue,

unsignedAttrs [1] IMPLICIT UnsignedAttributes OPTIONAL }

Constructor Summary

SignerInfos()
Constructs an empty SignerInfos container.

Method Summary

void	addSigner(byte[] message0, java.security.cert.X509Certificate cert0, java.security.PrivateKey privKey0, SignedAttributes sAttr0, java.lang.String signedAlg0) Adds particular signer to SignerInfos.

Method Detail

addSigner

public void addSigner(byte[] message0,
                      java.security.cert.X509Certificate cert0,
                      java.security.PrivateKey privKey0,
                      SignedAttributes sAttr0,
                      java.lang.String signedAlg0)
               throws SMIMEException

Adds particular signer to SignerInfos. This function must be performed at least once.

Parameters:

message0 - message which will be used in process of signing if parameter sAttr0 is null

cert0 - owners certificate

privKey0 - owners private key

sAttr0 - container for Signed Attributes

signedAlg0 - specifies signing algorithm type

digestAlg0 - specifies digest algorithm type

Throws:

SMIMEException - in case of missing owners certificates or missing private keys. Also, exception could be thrown in super class addContent method.
