SignerInfo

public SignerInfo(DerInputStream derin)
           throws java.io.IOException,
                  ParsingException

Parses a PKCS#7 signer info.

Throws:

java.io.IOException

ParsingException

SignerInfo

public SignerInfo(DerInputStream derin,
          boolean oldStyle)
           throws java.io.IOException,
                  ParsingException

Parses a PKCS#7 signer info.

This constructor is used only for backwards compatibility with PKCS#7 blocks that were generated using JDK1.1.x.

Parameters:

derin - the ASN.1 encoding of the signer info.

oldStyle - flag indicating whether or not the given signer info is encoded according to JDK1.1.x.

Throws:

java.io.IOException

ParsingException
