Method Detail

addSigner

void addSigner(PrivateKey key,
             X509Certificate cert,
             String digestOID,

Parameters:

key - The private key used to digitally sign the message.

cert - The X.509 certificate whose public key matches up with the private key.

digestOID - The digest algorithm used to generate the message hash.

signedAttr - Signed attributes

unsignedAttr - Unsigned attributes.

Throws:

IllegalArgumentException
