Constructor Details

PdfSigGenericPKCS

private PdfSigGenericPKCS(PdfName filter,
 PdfName subFilter)

Creates a generic standard filter.

Parameters:

filter - the filter name

subFilter - the sub-filter name

Method Details

setSignInfo

void setSignInfo(PrivateKey privKey,
 Certificate[] certChain,
 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

void setExternalDigest(byte[] digest,
 byte[] RSAdata,
 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 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
