public SignerInfo (X500Name issuerName, BigInteger serial, AlgorithmId digestAlgorithmId, PKCS9Attributes authenticatedAttributes, AlgorithmId digestEncryptionAlgorithmId, byte[] encryptedDigest, PKCS9Attributes unauthenticatedAttributes)

public SignerInfo (DerInputStream derin)

Parses a PKCS#7 signer info.

Throws
IOException
ParsingException

public SignerInfo (DerInputStream derin, boolean oldStyle)

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
IOException
ParsingException

Public Methods

public void derEncode (OutputStream out)

DER encode this object onto an output stream. Implements the DerEncoder interface.

Parameters
out the output stream on which to write the DER encoding.
Throws
IOException on encoding error.

Throws
IOException

public String toString ()

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of: 

 getClass().getName() + '@' + Integer.toHexString(hashCode())

Returns
  • a string representation of the object.
