Field Detail

### hashAlgorithm

    protected java.lang.String hashAlgorithm

  The hash algorithm, for example "SHA1"

### provider

    protected java.lang.String provider

  The crypto provider

### pkcs

    protected PdfPKCS7 pkcs

  The class instance that calculates the PKCS#1 and PKCS#7

### name

    protected java.lang.String name

  The subject name in the signing certificate (the element "CN")

### externalDigest

    private byte[] externalDigest

### externalRSAdata

    private byte[] externalRSAdata

### digestEncryptionAlgorithm

    private java.lang.String digestEncryptionAlgorithm

Constructor Detail

### PdfSigGenericPKCS

    public PdfSigGenericPKCS(PdfName filter,
                             PdfName subFilter)

  Creates a generic standard filter.

  Parameters:
    `filter` - the filter name
    `subFilter` - the sub-filter name

Method Detail

### setSignInfo

    public void setSignInfo(java.security.PrivateKey privKey,
                            java.security.cert.Certificate[] certChain,
                            java.security.cert.CRL[] crlList)

  Sets the crypto information to sign.

  Parameters:
    `privKey` - the private key
    `certChain` - the certificate chain
    `crlList` - the certificate revocation list. It can be `null`

### setExternalDigest

    public void setExternalDigest(byte[] digest,
                                  byte[] RSAdata,
                                  java.lang.String digestEncryptionAlgorithm)

  Sets the digest/signature to an external calculated value.

  Parameters:
    `digest` - the digest. This is the actual signature
    `RSAdata` - the extra data that goes into the data tag in PKCS#7
    `digestEncryptionAlgorithm` - the encryption algorithm. It may must be `null` if the `digest` is also `null`. If the `digest` is not `null` then it may be "RSA" or "DSA"

### getName

    public java.lang.String getName()

  Gets the subject name in the signing certificate (the element "CN")

  Returns:
    the subject name in the signing certificate (the element "CN")

### getSigner

    public PdfPKCS7 getSigner()

  Gets the class instance that does the actual signing.

  Returns:
    the class instance that does the actual signing

### getSignerContents

    public byte[] getSignerContents()

  Gets the signature content. This can be a PKCS#1 or a PKCS#7. It corresponds to the /Contents key.

  Returns:
    the signature content
